This divisional application is a divisional application based on the Chinese patent application with application number 201980084133.2, application date December 19, 2019, and invention name “Management system for loop optical devices using edge curler”. Background Art

[0001] There are many diseases that can occur in the human eye, leading to mild deterioration to complete loss of vision. While contact lenses and glasses can compensate for some diseases, others may require eye surgery. Generally, eye surgery can be categorized into posterior segment surgery, such as vitreoretinal surgery, and anterior segment surgery, such as cataract surgery. Vitreoretinal surgery can address many different eye conditions, including but not limited to macular degeneration, diabetic retinopathy, diabetic vitreous hemorrhage, macular holes, retinal detachments, epiretinal membranes, and cytomegalovirus retinitis.

[0002] For cataract surgery, the surgical procedure may require an incision and the insertion of tools into the eye to replace the cloudy natural lens with an artificial lens ("IOL"). A large incision site may result in a longer postoperative healing time. In order to reduce this healing time, the typical operating procedure has been transformed into an incision of about 2 mm in size formed in the eye. Although this smaller size incision can reduce the postoperative healing time, as the size of the incision continues to decrease, problems such as the size and function of the insertion tool may arise. Typically, the insertion tool can be pre-loaded with an IOL, and once the cloudy natural lens is removed, the IOL can be inserted into the patient's eye. The insertion tool may include a plunger for forcing the IOL out of the mouth of the insertion tool. The plunger may have additional functions, including the folding and folding of the loop of the IOL. Once the incision has been formed, the insertion tool can be inserted into the eye through the incision, and the folded IOL can be dispensed into the eye by actuating the plunger. When the incision site is reduced, the size of the mouth of the insertion tool can be reduced accordingly. Summary of the invention

[0005] In yet another exemplary aspect, the present disclosure relates to a method for delivering an intraocular lens. The method may include rotating a pair of arms so that each of the arms engages a corresponding haptic extension of the intraocular lens, thereby moving the haptic extension upward along an inclined surface and onto an optical element of the intraocular lens. The method may further include pivoting a pair of edge folders that engage an edge of the intraocular lens to fold the optics over itself and move the intraocular lens into alignment with an aperture. The aperture may extend from a first end of a housing to a cavity formed in a first surface of the housing, the intraocular lens being disposed in the cavity. The method may further include actuating a drive system to dispense the intraocular lens from the aperture through a mouthpiece into an eye, wherein the mouthpiece is coupled to the housing.

[0006] Different aspects may include one or more of the following features. The aperture may include a first portion having a U-shaped cross-section and extending from the first end of the housing to the central portion of the cavity. The aperture may include a second portion having a smaller cross-section than the first portion and extending from the central portion of the cavity to the second end of the housing. The haptic optics management system may further include an intraocular lens disposed in the cavity, wherein the intraocular lens includes an optic and a haptic extension extending from the optic. One of the haptic extensions may extend from the optic to the first end portion. Another of the haptic extensions may extend from the optic to the second end portion.

[0022] For the purpose of promoting understanding of the principles of the present disclosure, reference will now be made to the implementations shown in the accompanying drawings, and specific language will be used to describe them. However, it should be understood that it may not be intended to limit the scope of the present disclosure. Those skilled in the art in the technical field involved in the present disclosure are generally fully able to envision any changes and further modifications to the described devices, instruments, methods, and any further applications of the principles of the present disclosure. Specifically, it is fully conceivable that the features, components, and / or steps described with reference to one or more implementations can be combined with the features, components, and / or steps described with reference to other implementations of the present disclosure. For simplicity, in some cases, the same reference numerals may be used throughout the accompanying drawings to refer to the same or similar parts.

[0023] Exemplary embodiments described herein relate generally to eye surgery. More specifically, exemplary embodiments relate generally to systems, methods, and devices for inserting an intraocular lens ("IOL") into an eye. Embodiments may include an insertion tool for preparing and delivering an IOL into a patient's eye, the insertion tool comprising a plunger, a mouthpiece, and a haptic optics management system. In some embodiments, the haptic management system can fold the IOL assembly and gather one or more haptics of the IOL assembly. The haptics extend from the optics of the IOL and stabilize the IOL when the IOL is disposed within the capsular bag of the eye. After the IOL is prepared, the plunger forces the IOL through the insertion tool and out of the mouthpiece.

[0024] Figure 1A schematic diagram of an insertion tool 100 is shown. In some embodiments, the insertion tool 100 may include a drive system 102, a plunger 104, a haptic optics management system (interchangeably referred to as "HOMS") 106, and a mouth 108. The drive system 102 may be any system or combination of components operable to actuate the plunger 104. For example, the drive system 102 may utilize a lever and / or pneumatic system; a manually driven system or component; a hydraulic system; or other devices operable to drive the plunger 104 to advance, partially advance, or fully deliver the IOL from the insertion tool 100. The plunger 104 may be coupled to the drive system 102. The drive system 102 may be operable to actuate the plunger 104. For example, the drive system 102 may be driven, for example, electrically, mechanically, hydraulically, pneumatically, a combination thereof, or in some other manner. In response to the drive system 102, the plunger 104 moves through the HOMS 106. The HOMS 106 may be located between the drive system 102 and the mouth 108. In alternative embodiments, the HOMS 106 can be disposed at other locations within the insertion tool 100. In some embodiments, the HOMS 106 can contain the IOL 110 in a deployed position.

[0025] The drive system 102 may be any system, component, or group of components operable to advance the IOL 110 through the insertion tool 100. For example, the drive system 102 may include a plunger. Figure 1 Schematically shown in FIG. 1 is a plunger 104 that is operable to engage an IOL 110 disposed within the insertion tool 100 and advance the IOL 110 within the insertion tool 100. In some cases, the plunger 104 is operable to eject the IOL 110 from the insertion tool 100.

[0026] In some embodiments, the drive system 102 can be a manually driven system. That is, in some embodiments, the user applies force to operate the drive system 102. The exemplary drive system 102 includes a plunger 104, which can be directly or indirectly manually engaged by the user to push the plunger 104 through the insertion tool 100. When advancing, the plunger 104 engages the IOL 110 and advances the IOL 110 through the insertion tool 100, which can also include discharging the IOL 110 from the insertion tool 10. A non-limiting example of a manual IOL insertion tool is shown in U.S. Patent Application Publication No. 2016 / 0256316, the entire contents of which are incorporated herein by reference in their entirety. According to other implementations, the drive system 102 can be an automated system. U.S. Patent No. 8,808,308, U.S. Patent No. 8,308,736 and U.S. Patent No. 8,480,555 show an exemplary automated drive system, the entire contents of each patent being incorporated herein by reference in their entirety. Further, other automated drive systems within the scope of the present disclosure are described in U.S. Patent No. 8,998,983 and U.S. Patent Application Publication No. 2017 / 0119522, the entire contents of each of which are incorporated herein by reference in their entirety. Although exemplary drive systems are provided as examples, these systems are not intended to be limiting. On the contrary, any component, component group, system, device, mechanism, or combination thereof that can be operated to advance the IOL 110 is within the scope of the present disclosure.

[0027] like Figure 1 As shown, IOL 110 is a single-piece IOL that includes an optic 114 and haptic extensions 112 extending from opposite sides of the optic 114. Figure 1 In the illustrated example IOL 110, the haptic extensions 112 are disposed 180° relative to each other along the outer periphery of the optical device 114. However, other types of IOLs are also within the scope of the present disclosure. For example, a multi-piece IOL may also be used in which the optical device 114 and one or more haptic extensions 112 are separate components.

[0028] IOL 110 can have a shape similar to that of an eye (e.g., Figure 2A 1. The IOL 110 may be formed from a variety of materials, including, but not limited to, silicone, acrylic, and / or combinations thereof. Other materials are also contemplated. Hap extensions 112 extend from the periphery of the optic 114 and serve to stabilize the IOL 110 when it is positioned within the eye.

[0029] In some cases, the HOMS 106 can be actuated to collapse the haptic extensions 112 over the optic 114 and fold the optic 114. For example, the HOMS 106 can operate to fold the haptic extensions 112 over the optic 114 and fold the optic 114 over or around the folded haptic extensions 112. An IOL 110 in a folded configuration is shown at 116. The folded IOL 116 can include one or more haptic extensions 112 that are folded relative to the optic 114, and in some cases, the optic 114 is folded relative to one or more of the haptic extensions 112. Once the HOMS 106 has folded the IOL 110, the plunger 104 can be advanced through the HOMS 106. As the plunger 104 moves through the HOMS 106, the plunger 104 displaces the folded IOL 116 from the HOMS 106. For example, the plunger 104 may force the folded IOL 116 into and through the mouth 108 .

[0030] Figure 2A The patient's eye 200 is shown being operated on with the insertion tool 100. As shown, the insertion tool 100 dispenses the folded IOL 116 into the patient's eye 200. In some embodiments, for example, an incision 202 is formed in the eye 200 by a surgeon. For example, in some cases, the incision 202 can be formed through the sclera 204 of the eye 200. In other cases, the incision can be formed in the cornea 209 of the eye 200. The size of the incision 202 can be set to allow a portion of the insertion tool 100 to be inserted so as to deliver the folded IOL 116 into the capsular bag 208. For example, in some cases, the size of the incision 202 can have a length of less than about 2000 microns (2 mm). In other cases, the length of the incision 202 can be from about 0 microns to about 500 microns, from about 500 microns to about 1000 microns, from about 1000 microns to about 1500 microns, or from about 1500 microns to about 2000 microns.

[0031] After forming the incision 202, the insertion tool 100 is inserted through the incision into the interior portion 206 of the eye 200. The insertion tool 100 is actuated to dispense the folded IOL 116 into the capsular bag 208 of the eye 200. Upon dispensing, the folded IOL 116 returns to its initial unfolded state, and the IOL 110 is disposed within the capsular bag 208 of the eye 200, as shown in FIG. Figure 2BAs shown. The capsular bag 208 holds the IOL 110 within the eye 200 in a relationship relative to the eye 200 such that the optics 114 refracts light directed toward the retina (not shown). The haptic extensions 112 of the IOL 110 engage the capsular bag 208 to secure the IOL 110 therein. After the IOL 110 is dispensed into the capsular bag 208, the insertion tool 100 is removed from the eye 200 through the incision 202, and the eye 200 is allowed to heal over a period of time.

[0032] Figures 3 to 5 An exemplary insertion tool 100 operable to deliver an IOL into an eye is shown. As shown, the insertion tool 100 includes a drive system 102, a haptic optical device management system 106, and a mouth 108. The insertion tool 100 may also include a plunger, which may be similar to Figure 1 The plunger 104 is shown. In some cases, the plunger can be actuated to cause the IOL (e.g., which can be similar to Figure 1 An IOL 110 ) is advanced within the insertion tool 100 , and in some cases, the IOL 110 is dispensed from the insertion tool 100 .

[0033] refer to Figure 3 , the drive system 102 includes a body 302 and a lever 304 that can be pivotally connected to the body 302. The nozzle 108 is connected to the distal end 308 of the body 302. The HOMS 106 is disposed between the body 302 and the nozzle 108. In some cases, the nozzle 108 can be integrally connected to the body 302. In other cases, the nozzle 108 can be separated from the body 302 and can be connected to the body 302 via an interlocking relationship. In some cases, the HOMS 106 and the nozzle 108 can be integrally formed. In other cases, the HOMS 106, the nozzle 108 and the body 302 can be integrally formed.

[0034] In some cases, the body 302 can have an elongated, elongated shape. In some cases, the body 302 can have a first portion 310 and a second portion 312. In some cases, the first portion 310 and the second portion 312 are joined along a longitudinally extending interface. In the example shown, the first portion 310 includes a plurality of orifices 314. A plurality of protrusions 316 formed on the second portion 312 can be received in the orifices 314 to join the first portion 310 and the second portion 312. The protrusions 316 can form an interlocking fit with the orifices 314. However, Figures 3 to 5 The configuration of the body 302 of the exemplary insertion tool 100 shown is only a non-limiting example. In some cases, the body 302 can be a single integral piece. In some cases, the body 302 can include one or more cylindrical pieces. In addition, the body 302 can be constructed from any number of parts in any desired manner.

[0035] Continue to refer Figures 3 to 5 , the body 302 also includes reliefs 318, 319, and 320. The reliefs 318, 319, and 320 are shallow recesses formed in the body 302 to accommodate, for example, one or more fingers of a user. One or more of the reliefs 318, 319, and 320 may include a textured surface 322, which may provide the user with improved grip and control of the insertion tool 100. Figure 3 and Figure 5 As shown, relief 318 may include textured surface 322. However, the scope may not be limited in this regard. Rather, any, all, or none of reliefs 318, 319, and 320 may include textured surface 322. Similarly, lever 304 may also include textured surface 324. However, in some cases, lever 304 may not include a textured surface.

[0036] refer to Figure 3 , the mouth 108 includes a distal tip 326 defining an opening 328. The mouth 108 also includes a flared portion or wound guard 330. The distal tip 326 can be adapted to be inserted into an incision formed in the eye, such as the incision 202 shown in FIG. 2 , to deliver a folded IOL therein. The wound guard 330 can include an end face 332 operable to contact an outer surface to limit the depth to which the distal tip 326 penetrates the eye. In some embodiments, the wound guard 330 can be omitted.

[0037] In some embodiments, the insertion tool 100 can be preloaded. That is, when provided to the end user, the insertion tool 100 can include an IOL disposed therein. In some cases, the IOL can be disposed in the insertion tool 100 in an expanded state and is ready to be delivered to the patient. Preloading the insertion tool 100 with an IOL reduces the number of steps that the user must perform before the IOL is delivered to the patient. For example, the preloaded insertion tool 100 eliminates any steps that the user would otherwise perform to load the insertion tool 100 with an IOL. By reducing the number of steps, the errors and risks associated with delivering the IOL to the patient can be reduced. Further, the amount of time required for delivering the IOL can also be reduced. In some embodiments, the IOL can be preloaded into the HOMS 106.

[0038] Figure 6 A close-up view of an exemplary insertion tool 100 having a haptic optics management system 106 is shown. As previously described, the HOMS 106 is operable to fold an IOL (e.g., Figure 1For example, in some cases, HOMS 106 may be operable to fold IOL 110 from an unstressed state to a fully folded configuration, such as Figure 1 During folding, the HOMS 106 can gather or fold the haptic extension 112 over the optic 114 of the IOL 110 and fold the edge of the optic 114 over the gathered haptic extension 112, thereby capturing the haptic extension 112 and thereby placing the IOL 110 in a folded configuration, such as Figure 1 shown.

[0039] like Figures 3 to 6 As shown, for example, the HOMS 106 is sized to be commensurate with the size of the insertion tool 100. That is, the HOMS 106 has a compact size to avoid or limit the amount of obstruction to the surgeon's field of view when inserting the IOL into the eye. However, the scope of the present disclosure is not limited in this regard. Rather, in some cases, the size and / or shape of the haptic optics management system can be selected to be any desired size or shape. Further, while the HOMS 106 is shown as being disposed at the distal end of the insertion tool 100, the haptic optics management system 106 can be disposed anywhere within or along the insertion tool 100. In some embodiments, the HOMS 106 can be disposed between the mouth 108 and the drive system 102.

[0040] exist Figures 3 to 6 In the illustrated example of , the HOMS 106 is disposed between the distal end 308 of the body 302 and the mouth 108. In some cases, the HOMS 106 can be removably coupled to the mouth 108 and / or the drive system 102. For example, the HOMS 106 can be removably coupled to the body 302 using fasteners or adhesives. In other implementations, the HOMS 106 can be coupled to the body 302 via a snap-fit ​​engagement or any other desired connection method. Without limitation, exemplary fasteners can include nuts and bolts, washers, screws, pins, sockets, rods and studs, hinges, and / or any combination thereof.

[0041] Figure 7 An exemplary haptic optics management system 106 is shown. In the example shown, HOMS 106 includes a housing 702, an arm 704, and an edge crimper 706. Housing 702 forms a cavity 707 that receives IOL 110. As shown, IOL 110 is disposed in cavity 707 formed in housing 702.

[0042] The arms 704 are pivotally attached to the housing 702 and pivot about respective axes 709. In some cases, the axes 709 can be parallel to the optical axis 690 of the optical device 114. In other implementations, the axes 709 can have other orientations relative to the optical device 114. The edge crimper 706 is pivotally received in the housing 702. The edge crimper 706 is pivoted about an axis 715 (e.g., Fig.10 Each arm 704 engages one of the loop extensions 112. When actuated (described in more detail below), the arms 704 cause the loop extensions 112 to fold over and onto the optical device 114. The edge folders 706 receive the lateral edges of the optical device 114 into grooves formed in each respective edge folder 706, as described in more detail below. When actuated, the edge folders 706 move about a respective axis (e.g., Fig.10 The optic 114 is pivoted inwardly about the axis 1005 on the optic 114 so that the optic 114 is folded into a U-shape. In some cases, the arm 704 is first operated to fold the haptic extension 112 onto the optic 114, and the edge crimper 706 is operated after the arm 704 is operated so that the optic 114 is folded and captures the haptic extension 112, thereby placing the IOL 110 in the folded configuration, such as Figure 1 The IOL 116 is shown folded.

[0043] Each arm 704 includes a protrusion 717 extending therefrom. Protrusions 717 can be used to rotate arms 704 about axis 709. In some cases, a user can engage protrusions 717 to actuate arms 704. In other cases, a device, mechanism, or system can be used to actuate arms 704. An exemplary cam device for actuating arms and other components of an exemplary haptic optics management system is described in detail below with respect to another exemplary haptic optics management system.

[0044] Additional references Fig. 9 , a perspective view of one of the arms 704 is shown. There may be multiple arms 704. Arms 704 may be made of any suitable material. Suitable materials may include, but are not limited to, metals, non-metals, polymers, ceramics, and / or combinations thereof. Arms 704 may have any suitable size, height, and / or shape. Without limitation, suitable shapes may include, but are not limited to, cross-sectional shapes of circles, ellipses, triangles, rectangles, squares, hexagons, and / or combinations thereof.

[0045] In the illustrated embodiment, arm 704 includes a first portion 710 and a second portion 712. First portion 710 and second portion 712 are joined at bend 714. Pin 716 extends from first portion 710. Pin 716 is received in a hole (e.g., Figure 8826 as shown, and the arm 704 pivots about the pin 716. The protrusion 717 extends from the second portion 712 on the side of the arm opposite to the pin 716. As explained above, the protrusion 717 can be used to actuate the arm 704 so that the arm 704 pivots about the pin 716. The external force can be applied to the protrusion 717 using any suitable technique. In an embodiment, an operator (not shown) can grasp and turn the protrusion 717, thereby rotating the entire arm 704 about the pin 716. The arm 704 also includes a protrusion 718 that extends from the second portion 712 on the side opposite to the protrusion 717. The protrusion 718 is operable to engage the haptic extension 112 of the IOL 110 so as to fold the haptic extension 112 during actuation of the HOMS 106.

[0046] Additional references Fig.10 , showing a perspective view of an edge curler 706. There may be a plurality of edge curlers 706. The edge curler 706 may be made of any suitable material. Suitable materials may include, but are not limited to, metals, non-metals, polymers, ceramics, and / or combinations thereof. The edge curler 706 may have any suitable size, height, and / or shape. In the illustrated embodiment, the edge curler 706 includes a slot 1000 formed in the first surface 1002. The slot 1000 is adapted to receive a portion of an IOL's optic (such as the optic 114 of the IOL 110). The edge curler 706 also includes a hole 1004 formed adjacent the slot 1000. When mounted in the housing 702, the hole 1004 is aligned with the hole 838 formed in the housing 702 (e.g., at Figure 8 1004 and 838 to secure the edge crimper 706 in the housing 702 such that the edge crimper 706 pivots about the axis 715. A protrusion 1006 extends from a side 1008 opposite the first surface 1002. The protrusion 1006 can be used to rotate the edge crimper 706 about the hole 1004. In some cases, a user can engage the protrusion 1006 to actuate the edge crimper 706, thereby causing the edge crimper 706 to pivot about the hole 1004 in the direction of arrow 1010. In other cases, a device, mechanism, or system can be used to actuate the edge crimper 706. An exemplary cam device for actuating arms and other components of an exemplary haptic optics management system is described in detail below with respect to another exemplary haptic optics management system.

[0047] Additional references Figure 8, showing the housing 702 in more detail. The housing 702 can be made of materials such as metal, non-metal, polymer, ceramic, and / or combinations thereof. The housing 702 can have any size and / or shape. For example, but not limited to, the housing 702 can be shaped so that all or a portion of the housing 702 can have a cross-sectional shape that is circular, oval, triangular, rectangular, square, hexagonal, and / or combinations thereof. In some embodiments, all or a portion of the housing 702 can have a rectangular cross-sectional shape.

[0048] The housing 702 includes a bore 800 that traverses the entire length of the housing 702 from a first end 802 of the housing 702 to a second end 804 of the housing 702. The bore 800 defines a path through which a plunger (e.g., Figure 1 The plunger 104 (shown) is advanced through the path to engage the IOL 110 and drive the IOL 110 through the HOMS 106. In some implementations, the plunger continues to drive the IOL 110 through the mouth of the insertion tool and ejects the IOL 110 from the insertion tool. Figure 8 In the example shown, the first portion 801 of the hole 800 extending distally from the cavity 707 formed in the housing 702 has a U-shaped cross-section. However, the scope of the present disclosure is not limited in this regard. In other implementations, the hole 800 may have a circular, oval, rectangular, square, triangular, polygonal cross-sectional shape, or any other cross-sectional shape. The cross-sectional size of the second portion 803 of the hole 800 is smaller than the cross-sectional size of the first portion 801. Further, the cross-sectional shape of the second portion 803 is different from the cross-sectional shape of the first portion 801. In particular, as Figure 8 As shown, the second portion 803 has a circular cross-sectional shape. However, other cross-sectional shapes and sizes of the first portion 801 and the second portion 803 (such as those described above) are within the scope of the present disclosure. Further, in some cases, the cross-sectional size and shape of the first portion 801 and the second portion 803 can be the same. The cross-sectional size of the second portion 803 can be smaller than the cross-sectional size of the first portion 801 because the second portion 803 can be used to pass a plunger, which is generally smaller than the size of the folded IOL.

[0049] The cavity 707 is formed in the first surface 806 of the housing 702 and receives the IOL 110 therein. In some embodiments, one or more portions of material may be missing from the first surface 806 to form the cavity 707. The first surface 806 may be any suitable side of the housing 702. In the embodiment shown, the first surface 806 may be formed in any suitable side of the housing 702. In the embodiment shown, the first surface 806 having the cavity 707 may be the top side of the housing 702.

[0050] The cavity 707 includes a first end portion 808, a second end portion 810, and a center portion 812. The center portion 812 is deeper than the first end portion 808 and the second end portion 810 because the center portion 812 extends a greater distance in the housing 702. The IOL 110 is received in the cavity 707 of the housing 702 such that the optic 114 of the IOL 110 is suspended from the center portion 812. The base 814 of the center portion 812 can conform to the base of the aperture 800. Thus, in the example shown, the base 814 has a U-shaped cross-sectional shape. The center portion 812 also includes a platform 816 that is laterally offset from the base 814. In Figure 8 802, one of the platforms 816 is obscured by a portion of the housing 702. The platform 816 is raised relative to the base 814, but is recessed below the first end portion 808 and the second end portion 810. A slot 818 is formed in the side wall 820. The slot 818 is adapted to receive the protrusion 1006 of the edge crimper 706.

[0051] The first end portion 808 and the second end portion 810 each include an inclined surface 822, a raised platform 824, a hole 826 formed in the raised platform 824, and an end wall 828. The end wall 828 has an arcuate shape that conforms to the curvature of the haptic extension 112 of the IOL 110. The curvature of the end wall 828 helps to maintain the IOL 110 in the housing 702 in a desired orientation. In other implementations, the end wall 828 can have other shapes. For example, the shape of the end wall 828 is a non-arc shape that conforms to a non-arc haptic. In other implementations, the shape of the end wall 828 may not correspond to or otherwise conform to the shape of the haptic extension 112 of the IOL 110. The end wall 828 and the raised platform 824 combine to form a recess 830. When the arm 704 is in an unactuated state, the recess 704 can be at least partially received on the raised platform 824.

[0052] A portion 832 of the first end portion 808 and the second end portion 810 disposed between the end wall 828 and the inclined surface 822 (defining a haptic for receiving the IOL 110 when the IOL 110 is in an unstressed state (e.g., Figure 7The portion 832 helps to position the IOL 110 disposed within the cavity 707 of the housing 702 in a desired orientation. As shown, the shape of the portion 832 can be arcuate, but the portion 832 can be formed in other ways as needed for a particular application. The arm 704 is supported by a raised platform 824, wherein the pin 716 of the arm 704 is received in the hole 826. As described above, the arm 704 can pivot about the pin 716 within the hole 826. When the haptic is displaced by the arm 704, the inclined surface 822 operates to lift the haptic of the IOL above the optical device. The inclined surface 822 can be disposed at any suitable location on the respective first end portion 808 and second end portion 810, and can be set to any suitable angle. As shown in FIG. Figure 8 As shown, the inclined surface 822 includes a groove 834 that matches the path traveled by the protrusion 718 of the arm 704 when the arm 704 pivots about the axis 709 with the pin 716 as the pivot. As further shown, the first end 840 of the inclined surface 822 can be tangentially aligned with the central portion 812 of the cavity 707. The second end 842 of the inclined surface 822 can be adjacent to the portion 832.

[0053] The edge folder 706 can be received within the central portion 812 of the cavity 707, on the platform 816. The hole 838 in the housing 702 can be aligned with the hole 713 in the edge folder 706. As explained above, a pin (not shown) extends through the aligned hole 1004 of the edge folder 706 and the hole 713 formed in the housing 702, so that the edge folder can be pivoted about the axis 715. The protrusion 1006 of the edge folder 706 is received in the slot 818. In the unactuated position, the protrusion 1006 rests on the closed end 836 of the slot 818. In the unactuated position, the protrusion 1006 of the edge folder 706 can be perpendicular to the side wall 820. However, in other implementations, the protrusion 1006 can be arranged in other orientations relative to the side wall 820. By installing the edge folder 706 in the housing 702 , the lateral edge of the IOL installed in the cavity 707 is received in the slot 1000 formed in the edge folder 706 .

[0054] Reference now Figure 7 and Figure 11 to Figure 12 The operation of the loop management system 106 in operation will now be described in more detail. Figure 7102. As shown, an operator may place an IOL 110 in the housing 702. In the illustrated embodiment, the IOL 110 may be disposed in the cavity 707 to preload the haptic optic management system 106. The IOL 110 may be placed in the cavity 707 in a relaxed or initial state, wherein the haptic extension 112 extends from the optic 114. The haptic extension 112 may be disposed on a portion 832 of the cavity 707. At least a portion of an edge 719 of the IOL 110 may be retained by the edge crimper 706. As shown, at least a portion of the edge 719 of the IOL 110 may be disposed within a slot 1000 of the edge crimper 706. In the illustrated embodiment, the edge crimper 706 may secure the IOL 110 in the central portion 812 (e.g., Figure 8 shown).

[0055] Fig.11 Actuation of the arm 704 according to the present embodiment is shown to move the haptic extension 112 onto the optic 114 of the IOL 110. As previously described, embodiments can include applying a force to the protrusion 717 of the arm 704 to rotate the arm 704 about the first portion 710 of the arm 704. As the force rotates and moves the arm 704, the arm 704 can engage the haptic extension 112 of the IOL 110, causing them to move upward along the inclined surface 822. In embodiments, the arm 704 can fold the haptic extension 112 over the top of the optic 114. In the embodiment shown, the second portion 712 of the arm 704 can engage the haptic extension 112, causing the haptic extension 112 to move along the inclined surface 822 of the housing 702. As the haptic extension 112 moves along the inclined surface 822 , the haptic extension 112 moves upward so that the haptic extension 112 can move off the inclined surface 822 and onto the top of the optic 114 of the IOL 110 .

[0056] Fig.12 Actuation of the edge crimper 706 according to the present embodiment is shown to fold the IOL 110. As previously described, embodiments can include applying a force to the protrusions 1106 of the edge crimper 706, thereby causing the edge crimpers 706 to each pivot in an arc 1200. When the force causes the edge crimper 706 to pivot, the optic 114 of the IOL 110 can be forced to fold on itself because the optic 114 can be at least partially disposed in the slot 1000 of the edge crimper 706 (e.g., see FIG. 1 ). Fig.10 In addition, the edge crimper 706 can pivot in an arc 1200 to move the IOL 110 into the hole 800 formed in the housing 702.
