the lens capsule) and extracapsular ( in which the anterior capsule is removed with the lens, and the posterior capsule is left intact).
Since Ridley implanted the first artificial lens in about 1949, the problems associated with cataract extraction and lens implantation have received a great deal of attention from ophthalmic surgeons. Various types of artificial lenses have been proposed, and appropriate surgical procedures have been developed which strive to reduce patient discomfort and to reduce postoperative complications.

214~74l:
skilled artisans have disclosed intraocular lens structures comprising an optical zone portion generally made of rigid materials such as glass or plastics suita~le for optical use.
However, one of the principal disadvantages of the conventional rigid intraocular lens is that implantation of the lens requires large incisions in the ocular tissue. This type of surgical procedure leads to a relatively high complication rate, among other lo disadvantages. For instance, the serious dangers associated with implantation of a rigid lens ::~LU~;
include increased risk of infection, retinal de~al ~, and laceration of the ocular tissue, particularly with respect to the pupil.
~ccordingly, those skilled in the art have recognized 2 significant need for surgical tools for implantation of def ormable intraocular lens structures which afford the clinical advantages of using relatively small incision techniques, which provide a safer and more convenient surgical ~1oceduLe. In particular, those skilled in the art of deforma~le intraocular lenses and methods and devices for implantation, have also recognized a significant need for surgical tools which do not require widening of the wound made in the ocular tissue during or after implantation, but will deform the intraocular lens to a predetPrm; nPd cross section in a stressed state and which allow the ophthalmic sUrgeon to inspect the lens prior to implantation without manipulation in the eye. The present invention fulfills 3 0 these needs .

The present invention concerns a system including methods and devices f or implantation of intraocular lenses into the eye.
The surgical device according to the present invention includes the combination of a lens holder and a holder for the lens holder. The preferred lens holder comprises the combination of a lens receiver and an implantation nozzle. The lens receiver is preferably defined by a microcartridge comprising a split tubular WO 94/07436 PCr/l )S93/09255 - - - 21~
member having a f ixed tubular portion with an extension connected to a moveable tubular portion with an extension at a hinge. This configuration allows the microcartridge to be opened to accept a deformable intraocular lens, and closed to condense the lens into the passageway. The split tubular portion is connected to a nozzle with a continuous passageway passing through the tubular member and the nozzle.
The lens holder is inserted into a holder having means for driving or manipulating the lens from the lens holder into the eye. In the preferred ~ho~li L, the holder i5 provided with a plunger for driving the lens from the lens holder into the eye. Further, the holder is conf igured to receive a microcartridge having a 1~ nozzle.
The preferred holder includes means to prevent the microcartridge from rotating within the holder, and means for preventing the plunger from rotating within the holder. The means for preventing rotation of the microcartridge within the holder can be define by providing the microcartridge with one or more extensions that cooperate with the opening of the receiver of the holder to prevent rotation. The means for preventing the plunger from rotating within the holder can be defined by providing the plunger and a sleeve within the holder with a particular cross-sectional shape that prevents rotation, for example, a half-circle shape.
The preferred holder includes a plunger with a threaded cap cooperating with a threaded sleeve of the holder body for dialing the plunger forward within the holder f or precise and accurate movement of the lens during the implantation process. The holder is conf igured so that the plunger can be moved a .. _ .. . . .. . .. _ _ _ _ _ _ _ -2 ~
predetermined distance by sliding motion within the holder body followed by engagement of the threaded cap of the plunger with the threaded sleeve of the holder body to continue the forward pLUl~.a85 of the plunger tip.
The preferred plunger tip is defined by a faceted tip having various surfaces for moving and manipulating the lens from the lens holder and within the eye. The tip is designed to provide a clearance between the tip and the inner surface of the passageway through lens holder to a- -'Ate the trailing haptic and prevent damage thereto. Once the lens is inserted into the eye, the tip can be used to push and rotated the lens into proper position within the eye.
A method according to the present invention includes lubricating the surface of a deformable intraocular lens with a surgically compatible lubricant, and loading the lens into a microcartridge in the opened position. The microcartridge is closed while condensing the lens by a folding action into a shape so that it can be forced through the passageway in the microcartridge. The microcartridge is inserted into the holder with the plunger retracted.
The plunger is moved forward in a sliding manner by pushing the plunger forward while holding the holder body still. This action forces the lens from the tubular member portion of the microcartridge into the nozzle portion. At this point the threads of the threaded end cap of the plunger engage with the threads of the threaded sleeve. The threaded end cap is rotate slightly 3 o to engage the threads . The device is now ready f or the implantation process.

Description of Preferred ~hoAi- -The present invention is directed to a system including methods and devices for implantation of deformable intraocular lens structures for surgical placement in the eye.
An inventive device according to the present invention comprises a holder having a receiver, a lens holder that can be removably inserted into the receiver of the holder, and means such as a moveable plunger disposed within the holder to force and manipulate the lens from the lens holder into the eye.
Preferably, the lens holder is defined by a lens holding microcartridge for receiving the lens structure.
Further, the microcartridge is preferably a structure configured to be opened and closed. The preferred embodiment of the microcartridge receives a lens having prescribed memory characteristics when in the open position, and performs the function of folding or deforming the lens structure into a r~r~nrl~nc~c~
configuration when being closed. Alternatively, the microcartridge can be a structure having a passageway defined by a continuous walled annulus, and a lens could _ _ . _ _ _ .. , . .. .. ... . . _ .. _ .. . ... , . . .. _ _ _ _ _ WO 94/07436 PCr/US93/09~55 be inserted into the passageway from the end of microcartridge by compressing, rolling, folding, or combination of these techniques prior to insertion into the microcartridge.
Once a lens is positioned into the microcartridge, the microcartridge is positioned into a plunger device.
The assembled device maintains the lens in its condensed conf iguration during insertion into the eye yet permits the deformed lens to return to its original configuration, size and fixed focal length once implanted in the eye, thereby providing a safe, convenient, and comfortable surgical ~rucedure.
A pref erred embodiment of a def ormable intraocular lens implantation device 10 according to the present invention i5 shown in Figures 1,~ 2 and 3. The implantation device comprises a microcartridge 12 po~-~ within a holder 13 comprising a holder body 14 with a receiver 15, and a moveable plunger 16. In Figure 1, the receiver 15 is def ined by an opening 17 through the wall of the holder body 14 of the size and shape shown in Figures 1 and 2 . The opening 17 is def ined by parallel edges 17a, 17a, which are sufficiently spaced apart to allow the microcartridge 12 to be loaded into the receiver 15 of the holder 13, tapered edges 17b, clamping edges 17c, and stop edge 17d. In Figure 1, the microcartridge 12 is positioned in the receiver 15 between the clamping edges 17c with the plunger ~-t~n~ling through the microcartridge 12 in a position, for exarlple, after a lens implantation procedure.
3 0 In Figure 2, the lens holding microcartridge 12 is shown removed from the holder 13 with the plunger 16 in a retracted position for ~ w;n~ the microcartridge 12 containing a loaded lens and its haptic to be inserted _ _ _ _ _ . . : _ _ : .. .. _ . . . _ .
-W094/07436 ~174L PCI`/US93~09255 within the holder 13. In Figure 3, the holder 13 is shown with the plunger 16 in the extended position without the microcartridge 12 for purposes of illustration of the components.
The plunger 16 is f itted with a threaded end cap 18 at one end, and fitted with a tip 20 at an opposite end.
The threaded end cap 18 is provided with a plurality of grooves 22 to a allow a person to tightly grip the cap 18 with his or her f inger tips . The threaded end cap 18 is received within a threaded sleeve 24 of the insert holder 14. The threaded end cap 18 can be a separate _ -nPnt attached to the insert holder 13, or integral therewith, as shown in the construction is Figure 5.
The plunger 16 is installed within the holder 13 in a manner to allow the plunger to be reciprocated therein.
In the illustrated PT~I-O~l; L, the plunger 16 is supported for sliding r ~vc t within the holder 13 by guide 26, as shown in Figures 5 and 6. The outer dimension of the guide 26 is approximately the same size as the inner dimensions of the holder 13 to allow the guide to be inserted within the insert holder. During construction, the guide 26 is inserted within the holder 13, and locked into position by pin 28 inserted into a predrilled hole in both the wall of the holder 13 and guide 26.
The cross-sectional shape of the plunger 16 as well as the shape of the inner surf ace of the guide 2 6 are approximately a half-circle, as shown in Figure 6. This arrangement prevents the plunger i6 from rotating within the holder 13 to maintain the orientation of the tip 20 relative to the holder 13 during operation.
W0 94/07436 ~ 7 4 1 PCr/US93/09255 ., The threaded end cap 18 is connected to the plunger 16 in a manner to allow the threaded end cap 18 to be rotated relative to the plunger 16. For example, the left end of the plunger 16 (Figure 5) is provided with a threaded extension 30, which is secured to the threaded end cap 18 by a nut 32. Specifically, the threaded end cap 18 is manufactured with external threads 34 and a longitudinal center bore 36 that ends on the right side of the threaded end cap 18 leaving a wall 38.
The wall 38 is provided with a hole slightly larger than the outer diameter of the threaded extension 34 to allow the threaded end cap 18 to freely rotate on the plunger 16 while being secured to the end of the plunger 16. During cu~aL.u1Lion, the nut 32 is inserted through the center bore 36 and threaded onto the extension 30 to 6ecure the threaded end cap 18 to the plunger 16. A
curved cap 40 is press fitted into the end of the center bore 36 to seal the center bore 36 to prevent debris from entering therein during use.
The details of the tip ~IL~ny L are shown in Figures 7 to 12. The plunger 16 is manufactured with an extension 42 supporting tip 20. The tip 20 aLLuL:LuLe provides means for inserting the deformable intraocular lens into the eye and manipulating the lens within the eye after the insertion step. For example, the tip 20 is faceted in the manner shown in the figures. Specifically, the left side of the tip 20 shown in Figure 8 i8 provided with a flat surface facet 42, conical surface 44, and cylindrical surface 46. The right side shown in Figure 11 is provided with a concave surface facet 50.
WO 94/07436 PCr/l~S93J09255 21~7~:1 The end face of the tip 20 is designed to push the lens into position once inserted into the eye. For example, the end face is defined by a concave cylindrical surface 52 shown in Figure 8.
Suitable deformable intraocular lens for use in the present invention are shown in Figures 13 - 15. The deformable intraocular lens 54 shown in Figures 13 and 15 includes a lens body 56 with attachment means defined by a pair of haptics 58 each having one end anchored in the lens portion 56 and a free end ~or attachment to the eye tissue. The deformable intraocular lens 60 shown in Figure 14 includes a lens body 62 and at~AI' L means defined by a pair of lateral lobes 64 of the lens portion 62 .
The details of the preferred lens holding microcartridge 12 are shown in Figures 16 - 20. The microcartridge 12 comprises a split tubular member 66 extending to a continuous tubular member 67 and an implantation nozzle 68. When the microcartridge is in a closed position, a continuous circular or oval passageway of the same diameter extends through the split tubular member 66 through the continuous tubular member 67 and through the implantation nozzle 68. The microcartridge is preferably made of injection molded plastic such as polypropylene The split tubular member 66 is defined by a fixed portion 70 and a moveable portion 72. The fixed portion 70 is fixed relative to the implantation nozzle 68, and is defined by a tubular portion 74 and extension 72. The moveable portion 72 is moveable relative to the fixed portion 70 for opening and closing the split tubular member 66. The moveable portion 72 is defined by a tubular portion 78 and extension 80. A hinge 82 is provided between the f ixed portion 7 0 and moveable WO 94/07436 PCI~/US93/09255 2-1447~i portion 72. The hinge 82 is defined by reducing the thickness of the walls of the tubular portion 74 and 75 at the hinge 82, as shown in Figures 17, 18 and 19. The hinge 82 runs the length of the split tubular member 66 to allow the extension 76 and 78 to be split apart, or brought together to open and close, respectively, the split tubular member 66.
The tubular portion 78 of the moveable portion 72 is provided with a sealing edge 84, which is exposed when the lens holding microcartridge 12 is opened, as shown in Figure 16A, and seals with a similar sealing edge 86 (See Flgures 17 and 21) of the continuous tubular member 67 when the lens holding microcartridge is closed.
The end of the tip 2 0 is provided with three ( 3 ) equally spaced slots 87a, 87b and 87c of different length provided about the circumference thereof, as shown in Figures 20A and 20B. The slot 87a positioned at the top of the tip 20 is the shortest, slot 87c on the right side of the tip 20 is the longest, and slot 87b on the left side is of medium length. The slots 87a, 8?b, 87c cause the lens 54 to rotate as it exits the tip 20.
Other ~mhorl; I s of the mi~iLu- ~' L~ idge 12 according to the present invention are shown in Figures 30-33.
The mi~;L U~ClL Ll idge shown in Figure 3 0 is provided with a beveled tip 94 to facilitate entry of the tip through the incision in the eye during implantation. The beveled tip 94 can be set at approximately forty-f ive (45) degrees relative to the passageway through the microcartridge 12.
3 0 The embodiment of the microcartridge shown in Figures 31 and 32 is provided with a set of grooves 96 provided inside the passageway therethrough. The grooves accommodate the edges of the lens being loaded into the ~1~47~1 microcartridge to facilitate bending of the lens.
Specifically, the edges of the lens are placed in the grooves 96 to prevent relative slippage of the edges with the inner surface of the passageway through the microcartridge when the microcartridge is being f olded into the closed position The P~ nts of the microcartridge shown in Figures 33A and 33B each have a nozzle 68' having an oval cross-section with slots 87 ' differently position as shown, respectively, again to facilitate entry through an incision in the eye. Alternatively, the cross-section can be two half circles set apart and connected together rather than oval.
The various features of the microcartridges shown in Figures 16-21 and 30-33 can be used in various combinations to achieved an optimum design for a particular application. However, all of these features are typically considered improvements of the basic combination .
The components of the device 10, except for the microcartridge 12, are preferably fabricated from autoclavable material such as stainless steel or from a disposable rigid plastic such as medical grade ABS or the 1 ike .
METHODS OF IMPLANTATION
The surgical procedure begins by coating the lens with a surgically compatible lubricant, and loading the lens into the microcartridge. For example, as 6hown in Figure 21, a lens 54 having a lens body 56, a leading haptic 58a is load into the mi~:Lo~llLLLidge 12 while a trailing haptic 58b remains trailing outside the microcartridge in the manner shown. Specifically, the 21~7~1 .
lens 54 is loaded downwardly into the opened microcartridge 12 until it sits on the inner surfaces of the tubular portions 74 and 78, for example, with a pair of tweezers. The outer circumferential surface of the lens 54 are held by edges 88 and 90 of the tubular portions 74 and 78, respectively. The rear edge of the lens 54 is placed approximately at the rear edge of the microcartridge 12. The lens 54 is further ~-nirl-lAted to situate the haptics 58a and 58b in the manner shown.
Specifically, haptic 54a is positioned in a leading position and the other haptic 54b is positioned in a trailing position outside with respect to the direction of implantation, as indicated by the arrow .
Subsequently, the split tubular member 66 of the microcartridge 12 is closed about the lens 54 by forcing the extensions 76 and 80 together with his or her f inger tips. The inner surfaces of the tubular portions 74 and 78 bend and fold the lens 54 when the extensions 76 and 80 are forced together, as shown in Figures 22 and 23.
Due to the resilient nature of the deformable intraocular lens 54, the lens 54 conform to the curved inner surface of the tubular portions 74 and 78 without damage thereto, as shown in Figure 23.
The microcartridge 12 containing the loaded lens 54 is inserted between the edges 17a, 17a of the opening 17 into the receiver 15 of the holder 13. As the microcartridge 12 is moved forward, the extensions 76 and 80 move past the tapered edges 17b and come to a stop position between the clamping edges 17c when front portions of the extensions 76 and 80 contact with the stop edge 17d. The clamping edges 17c prevent rotation of the mi~:L~,cl' Lr idge inside the holder 13.

21~47~1 The user pushes the threaded end cap 18 forward while securing the holder body 14 from movement, forcing the plunger 16 forward within the holder. As the plunger 16 is moved forward, the tip 20 enters into the rear of the microcartridge 12 and misses the trailing haptic 58B
until the tip makes contact with the loaded lens 54, as shown in Figure 24. As the plunger 16 is moved forward in this manner, the lens 54 previously lubricated, is forced into the implantation nozzle 68 of the microcartridge 12, as shown in Figure 25.
Once the lens 54 enters the implantation nozzle 68, the threads of the end cap 18 contact with the threads of the sleeve 24 stopping further movement of the plunger 14 forward in this manner. The end cap 18 is slightly rotated to engage the threads of the end cap 18 with the threads of the sleeve 24. At this point, the surgical device is ready for the implantation step. The nozzle is insert through the incision in the eye, and the end cap 18 is rotated to continue the forward movement of the plunger 16 by continued rotation of the end cap 18 relative to the holder body 14 to expel the lens from the nozzle into the interior of the eye, as shown in Figure 2 6 . This manner of screw adv~nc~ t f or moving the plunger 16 forward provides for precise control and accuracy concerning forcing the lens 54 through the remaining portion of the tip 68 into the eye during the implantation procedure. The deformed lens after exiting the nozzle 16 returns to its original configuration, full size and fixed focal length.
After the lens is inserted into the eye, the end cap 18 is further rotated to fully expose the tip 20 of the plunger 16, as shown in Figures 28 and 29, to allow the lens to be pushed forward, side manipulated to rotate the WO 94/n7436 21~ ~ 7 D3 1 PCT/US93~09255 ' ' ~l lens, and pushed down to properly position the lens within the eye without the aid of other surgical instruments .
The configuration of the tip 20 is important during the implantation process . The f aceted tip 2 0 provides a clearance between the tip 20 and the inner surface of the passageway through the microcartridge 12 to ac -'Ate the trailing haptic 58b during movement of the lens within the microcartridge 12, as shown in Figures 25 and 26. Specifically, there exists a sufficient clearance between the flat surface facet 44 and the inner wall of the passageway through the microcartridge 12. During the implantation process, the trailing haptic f loats around in the space between the extension 42 of the tip 20 and the inner wall of the passageway, as shown in Figure 25.
This prevents any chance of damage to the trailing haptic, for example, by being caught between the tip 20 and the lens 54 during the implantation process. The leading haptic moves through the passageway llni ~-~9ed during the implantation process preventing any damage thereto .

Since Ridley implanted the first artificial lens in about 1949, the problems associated with cataract extraction and lens implantation have received a great deal of attention from ophthalmic surgeons. Various types of artificial lenses have been proposed, and appropriate surgical procedures have been developed which strive to reduce patient discomfort and to reduce postoperative complications.

skilled artisans have disclosed intraocular lens structures comprising an optical zone portion generally made of rigid materials such as glass or plastics suita~le for optical use.
However, one of the principal disadvantages of the conventional rigid intraocular lens is that implantation of the lens requires large incisions in the ocular tissue. This type of surgical procedure leads to a relatively high complication rate, among other lo disadvantages. For instance, the serious dangers associated with implantation of a rigid lens ::~LU~;
include increased risk of infection, retinal de~al ~, and laceration of the ocular tissue, particularly with respect to the pupil.
~ccordingly, those skilled in the art have recognized 2 significant need for surgical tools for implantation of def ormable intraocular lens structures which afford the clinical advantages of using relatively small incision techniques, which provide a safer and more convenient surgical ~1oceduLe. In particular, those skilled in the art of deforma~le intraocular lenses and methods and devices for implantation, have also recognized a significant need for surgical tools which do not require widening of the wound made in the ocular tissue during or after implantation, but will deform the intraocular lens to a predetPrm; nPd cross section in a stressed state and which allow the ophthalmic sUrgeon to inspect the lens prior to implantation without manipulation in the eye. The present invention fulfills 3 0 these needs .

The present invention concerns a system including methods and devices f or implantation of intraocular lenses into the eye.
The surgical device according to the present invention includes the combination of a lens holder and a holder for the lens holder. The preferred lens holder comprises the combination of a lens receiver and an implantation nozzle. The lens receiver is preferably defined by a microcartridge comprising a split tubular WO 94/07436 PCr/l )S93/09255 - - - 21~
member having a f ixed tubular portion with an extension connected to a moveable tubular portion with an extension at a hinge. This configuration allows the microcartridge to be opened to accept a deformable intraocular lens, and closed to condense the lens into the passageway. The split tubular portion is connected to a nozzle with a continuous passageway passing through the tubular member and the nozzle.
The lens holder is inserted into a holder having means for driving or manipulating the lens from the lens holder into the eye. In the preferred ~ho~li L, the holder i5 provided with a plunger for driving the lens from the lens holder into the eye. Further, the holder is conf igured to receive a microcartridge having a 1~ nozzle.
The preferred holder includes means to prevent the microcartridge from rotating within the holder, and means for preventing the plunger from rotating within the holder. The means for preventing rotation of the microcartridge within the holder can be define by providing the microcartridge with one or more extensions that cooperate with the opening of the receiver of the holder to prevent rotation. The means for preventing the plunger from rotating within the holder can be defined by providing the plunger and a sleeve within the holder with a particular cross-sectional shape that prevents rotation, for example, a half-circle shape.
The preferred holder includes a plunger with a threaded cap cooperating with a threaded sleeve of the holder body for dialing the plunger forward within the holder f or precise and accurate movement of the lens during the implantation process. The holder is conf igured so that the plunger can be moved a .. _ .. . . .. . .. _ _ _ _ _ _ _ -2 ~
predetermined distance by sliding motion within the holder body followed by engagement of the threaded cap of the plunger with the threaded sleeve of the holder body to continue the forward pLUl~.a85 of the plunger tip.
The preferred plunger tip is defined by a faceted tip having various surfaces for moving and manipulating the lens from the lens holder and within the eye. The tip is designed to provide a clearance between the tip and the inner surface of the passageway through lens holder to a- -'Ate the trailing haptic and prevent damage thereto. Once the lens is inserted into the eye, the tip can be used to push and rotated the lens into proper position within the eye.
A method according to the present invention includes lubricating the surface of a deformable intraocular lens with a surgically compatible lubricant, and loading the lens into a microcartridge in the opened position. The microcartridge is closed while condensing the lens by a folding action into a shape so that it can be forced through the passageway in the microcartridge. The microcartridge is inserted into the holder with the plunger retracted.
The plunger is moved forward in a sliding manner by pushing the plunger forward while holding the holder body still. This action forces the lens from the tubular member portion of the microcartridge into the nozzle portion. At this point the threads of the threaded end cap of the plunger engage with the threads of the threaded sleeve. The threaded end cap is rotate slightly 3 o to engage the threads . The device is now ready f or the implantation process.

Description of Preferred ~hoAi- -The present invention is directed to a system including methods and devices for implantation of deformable intraocular lens structures for surgical placement in the eye.
An inventive device according to the present invention comprises a holder having a receiver, a lens holder that can be removably inserted into the receiver of the holder, and means such as a moveable plunger disposed within the holder to force and manipulate the lens from the lens holder into the eye.
Preferably, the lens holder is defined by a lens holding microcartridge for receiving the lens structure.
Further, the microcartridge is preferably a structure configured to be opened and closed. The preferred embodiment of the microcartridge receives a lens having prescribed memory characteristics when in the open position, and performs the function of folding or deforming the lens structure into a r~r~nrl~nc~c~
configuration when being closed. Alternatively, the microcartridge can be a structure having a passageway defined by a continuous walled annulus, and a lens could _ _ . _ _ _ .. , . .. .. ... . . _ .. _ .. . ... , . . .. _ _ _ _ _ WO 94/07436 PCr/US93/09~55 be inserted into the passageway from the end of microcartridge by compressing, rolling, folding, or combination of these techniques prior to insertion into the microcartridge.
Once a lens is positioned into the microcartridge, the microcartridge is positioned into a plunger device.
The assembled device maintains the lens in its condensed conf iguration during insertion into the eye yet permits the deformed lens to return to its original configuration, size and fixed focal length once implanted in the eye, thereby providing a safe, convenient, and comfortable surgical ~rucedure.
A pref erred embodiment of a def ormable intraocular lens implantation device 10 according to the present invention i5 shown in Figures 1,~ 2 and 3. The implantation device comprises a microcartridge 12 po~-~ within a holder 13 comprising a holder body 14 with a receiver 15, and a moveable plunger 16. In Figure 1, the receiver 15 is def ined by an opening 17 through the wall of the holder body 14 of the size and shape shown in Figures 1 and 2 . The opening 17 is def ined by parallel edges 17a, 17a, which are sufficiently spaced apart to allow the microcartridge 12 to be loaded into the receiver 15 of the holder 13, tapered edges 17b, clamping edges 17c, and stop edge 17d. In Figure 1, the microcartridge 12 is positioned in the receiver 15 between the clamping edges 17c with the plunger ~-t~n~ling through the microcartridge 12 in a position, for exarlple, after a lens implantation procedure.
3 0 In Figure 2, the lens holding microcartridge 12 is shown removed from the holder 13 with the plunger 16 in a retracted position for ~ w;n~ the microcartridge 12 containing a loaded lens and its haptic to be inserted _ _ _ _ _ . . : _ _ : .. .. _ . . . _ .
-W094/07436 ~174L PCI`/US93~09255 within the holder 13. In Figure 3, the holder 13 is shown with the plunger 16 in the extended position without the microcartridge 12 for purposes of illustration of the components.
The plunger 16 is f itted with a threaded end cap 18 at one end, and fitted with a tip 20 at an opposite end.
The threaded end cap 18 is provided with a plurality of grooves 22 to a allow a person to tightly grip the cap 18 with his or her f inger tips . The threaded end cap 18 is received within a threaded sleeve 24 of the insert holder 14. The threaded end cap 18 can be a separate _ -nPnt attached to the insert holder 13, or integral therewith, as shown in the construction is Figure 5.
The plunger 16 is installed within the holder 13 in a manner to allow the plunger to be reciprocated therein.
In the illustrated PT~I-O~l; L, the plunger 16 is supported for sliding r ~vc t within the holder 13 by guide 26, as shown in Figures 5 and 6. The outer dimension of the guide 26 is approximately the same size as the inner dimensions of the holder 13 to allow the guide to be inserted within the insert holder. During construction, the guide 26 is inserted within the holder 13, and locked into position by pin 28 inserted into a predrilled hole in both the wall of the holder 13 and guide 26.
The cross-sectional shape of the plunger 16 as well as the shape of the inner surf ace of the guide 2 6 are approximately a half-circle, as shown in Figure 6. This arrangement prevents the plunger i6 from rotating within the holder 13 to maintain the orientation of the tip 20 relative to the holder 13 during operation.
W0 94/07436 ~ 7 4 1 PCr/US93/09255 ., The threaded end cap 18 is connected to the plunger 16 in a manner to allow the threaded end cap 18 to be rotated relative to the plunger 16. For example, the left end of the plunger 16 (Figure 5) is provided with a threaded extension 30, which is secured to the threaded end cap 18 by a nut 32. Specifically, the threaded end cap 18 is manufactured with external threads 34 and a longitudinal center bore 36 that ends on the right side of the threaded end cap 18 leaving a wall 38.
The wall 38 is provided with a hole slightly larger than the outer diameter of the threaded extension 34 to allow the threaded end cap 18 to freely rotate on the plunger 16 while being secured to the end of the plunger 16. During cu~aL.u1Lion, the nut 32 is inserted through the center bore 36 and threaded onto the extension 30 to 6ecure the threaded end cap 18 to the plunger 16. A
curved cap 40 is press fitted into the end of the center bore 36 to seal the center bore 36 to prevent debris from entering therein during use.
The details of the tip ~IL~ny L are shown in Figures 7 to 12. The plunger 16 is manufactured with an extension 42 supporting tip 20. The tip 20 aLLuL:LuLe provides means for inserting the deformable intraocular lens into the eye and manipulating the lens within the eye after the insertion step. For example, the tip 20 is faceted in the manner shown in the figures. Specifically, the left side of the tip 20 shown in Figure 8 i8 provided with a flat surface facet 42, conical surface 44, and cylindrical surface 46. The right side shown in Figure 11 is provided with a concave surface facet 50.
WO 94/07436 PCr/l~S93J09255 21~7~:1 The end face of the tip 20 is designed to push the lens into position once inserted into the eye. For example, the end face is defined by a concave cylindrical surface 52 shown in Figure 8.
Suitable deformable intraocular lens for use in the present invention are shown in Figures 13 - 15. The deformable intraocular lens 54 shown in Figures 13 and 15 includes a lens body 56 with attachment means defined by a pair of haptics 58 each having one end anchored in the lens portion 56 and a free end ~or attachment to the eye tissue. The deformable intraocular lens 60 shown in Figure 14 includes a lens body 62 and at~AI' L means defined by a pair of lateral lobes 64 of the lens portion 62 .
The details of the preferred lens holding microcartridge 12 are shown in Figures 16 - 20. The microcartridge 12 comprises a split tubular member 66 extending to a continuous tubular member 67 and an implantation nozzle 68. When the microcartridge is in a closed position, a continuous circular or oval passageway of the same diameter extends through the split tubular member 66 through the continuous tubular member 67 and through the implantation nozzle 68. The microcartridge is preferably made of injection molded plastic such as polypropylene The split tubular member 66 is defined by a fixed portion 70 and a moveable portion 72. The fixed portion 70 is fixed relative to the implantation nozzle 68, and is defined by a tubular portion 74 and extension 72. The moveable portion 72 is moveable relative to the fixed portion 70 for opening and closing the split tubular member 66. The moveable portion 72 is defined by a tubular portion 78 and extension 80. A hinge 82 is provided between the f ixed portion 7 0 and moveable WO 94/07436 PCI~/US93/09255 2-1447~i portion 72. The hinge 82 is defined by reducing the thickness of the walls of the tubular portion 74 and 75 at the hinge 82, as shown in Figures 17, 18 and 19. The hinge 82 runs the length of the split tubular member 66 to allow the extension 76 and 78 to be split apart, or brought together to open and close, respectively, the split tubular member 66.
The tubular portion 78 of the moveable portion 72 is provided with a sealing edge 84, which is exposed when the lens holding microcartridge 12 is opened, as shown in Figure 16A, and seals with a similar sealing edge 86 (See Flgures 17 and 21) of the continuous tubular member 67 when the lens holding microcartridge is closed.
The end of the tip 2 0 is provided with three ( 3 ) equally spaced slots 87a, 87b and 87c of different length provided about the circumference thereof, as shown in Figures 20A and 20B. The slot 87a positioned at the top of the tip 20 is the shortest, slot 87c on the right side of the tip 20 is the longest, and slot 87b on the left side is of medium length. The slots 87a, 8?b, 87c cause the lens 54 to rotate as it exits the tip 20.
Other ~mhorl; I s of the mi~iLu- ~' L~ idge 12 according to the present invention are shown in Figures 30-33.
The mi~;L U~ClL Ll idge shown in Figure 3 0 is provided with a beveled tip 94 to facilitate entry of the tip through the incision in the eye during implantation. The beveled tip 94 can be set at approximately forty-f ive (45) degrees relative to the passageway through the microcartridge 12.
3 0 The embodiment of the microcartridge shown in Figures 31 and 32 is provided with a set of grooves 96 provided inside the passageway therethrough. The grooves accommodate the edges of the lens being loaded into the ~1~47~1 microcartridge to facilitate bending of the lens.
Specifically, the edges of the lens are placed in the grooves 96 to prevent relative slippage of the edges with the inner surface of the passageway through the microcartridge when the microcartridge is being f olded into the closed position The P~ nts of the microcartridge shown in Figures 33A and 33B each have a nozzle 68' having an oval cross-section with slots 87 ' differently position as shown, respectively, again to facilitate entry through an incision in the eye. Alternatively, the cross-section can be two half circles set apart and connected together rather than oval.
The various features of the microcartridges shown in Figures 16-21 and 30-33 can be used in various combinations to achieved an optimum design for a particular application. However, all of these features are typically considered improvements of the basic combination .
The components of the device 10, except for the microcartridge 12, are preferably fabricated from autoclavable material such as stainless steel or from a disposable rigid plastic such as medical grade ABS or the 1 ike .
METHODS OF IMPLANTATION
The surgical procedure begins by coating the lens with a surgically compatible lubricant, and loading the lens into the microcartridge. For example, as 6hown in Figure 21, a lens 54 having a lens body 56, a leading haptic 58a is load into the mi~:Lo~llLLLidge 12 while a trailing haptic 58b remains trailing outside the microcartridge in the manner shown. Specifically, the 21~7~1 .
lens 54 is loaded downwardly into the opened microcartridge 12 until it sits on the inner surfaces of the tubular portions 74 and 78, for example, with a pair of tweezers. The outer circumferential surface of the lens 54 are held by edges 88 and 90 of the tubular portions 74 and 78, respectively. The rear edge of the lens 54 is placed approximately at the rear edge of the microcartridge 12. The lens 54 is further ~-nirl-lAted to situate the haptics 58a and 58b in the manner shown.
Specifically, haptic 54a is positioned in a leading position and the other haptic 54b is positioned in a trailing position outside with respect to the direction of implantation, as indicated by the arrow .
Subsequently, the split tubular member 66 of the microcartridge 12 is closed about the lens 54 by forcing the extensions 76 and 80 together with his or her f inger tips. The inner surfaces of the tubular portions 74 and 78 bend and fold the lens 54 when the extensions 76 and 80 are forced together, as shown in Figures 22 and 23.
Due to the resilient nature of the deformable intraocular lens 54, the lens 54 conform to the curved inner surface of the tubular portions 74 and 78 without damage thereto, as shown in Figure 23.
The microcartridge 12 containing the loaded lens 54 is inserted between the edges 17a, 17a of the opening 17 into the receiver 15 of the holder 13. As the microcartridge 12 is moved forward, the extensions 76 and 80 move past the tapered edges 17b and come to a stop position between the clamping edges 17c when front portions of the extensions 76 and 80 contact with the stop edge 17d. The clamping edges 17c prevent rotation of the mi~:L~,cl' Lr idge inside the holder 13.

21~47~1 The user pushes the threaded end cap 18 forward while securing the holder body 14 from movement, forcing the plunger 16 forward within the holder. As the plunger 16 is moved forward, the tip 20 enters into the rear of the microcartridge 12 and misses the trailing haptic 58B
until the tip makes contact with the loaded lens 54, as shown in Figure 24. As the plunger 16 is moved forward in this manner, the lens 54 previously lubricated, is forced into the implantation nozzle 68 of the microcartridge 12, as shown in Figure 25.
Once the lens 54 enters the implantation nozzle 68, the threads of the end cap 18 contact with the threads of the sleeve 24 stopping further movement of the plunger 14 forward in this manner. The end cap 18 is slightly rotated to engage the threads of the end cap 18 with the threads of the sleeve 24. At this point, the surgical device is ready for the implantation step. The nozzle is insert through the incision in the eye, and the end cap 18 is rotated to continue the forward movement of the plunger 16 by continued rotation of the end cap 18 relative to the holder body 14 to expel the lens from the nozzle into the interior of the eye, as shown in Figure 2 6 . This manner of screw adv~nc~ t f or moving the plunger 16 forward provides for precise control and accuracy concerning forcing the lens 54 through the remaining portion of the tip 68 into the eye during the implantation procedure. The deformed lens after exiting the nozzle 16 returns to its original configuration, full size and fixed focal length.
After the lens is inserted into the eye, the end cap 18 is further rotated to fully expose the tip 20 of the plunger 16, as shown in Figures 28 and 29, to allow the lens to be pushed forward, side manipulated to rotate the WO 94/n7436 21~ ~ 7 D3 1 PCT/US93~09255 ' ' ~l lens, and pushed down to properly position the lens within the eye without the aid of other surgical instruments .
The configuration of the tip 20 is important during the implantation process . The f aceted tip 2 0 provides a clearance between the tip 20 and the inner surface of the passageway through the microcartridge 12 to ac -'Ate the trailing haptic 58b during movement of the lens within the microcartridge 12, as shown in Figures 25 and 26. Specifically, there exists a sufficient clearance between the flat surface facet 44 and the inner wall of the passageway through the microcartridge 12. During the implantation process, the trailing haptic f loats around in the space between the extension 42 of the tip 20 and the inner wall of the passageway, as shown in Figure 25.
This prevents any chance of damage to the trailing haptic, for example, by being caught between the tip 20 and the lens 54 during the implantation process. The leading haptic moves through the passageway llni ~-~9ed during the implantation process preventing any damage thereto .
