Description

Technical Field

[0001] The present disclosure relates to a tactile and optical part management system using an edge roller.

Background Art

[0002] The human eye is susceptible to many diseases, causing anything from mild deterioration to complete vision loss. Contact lenses and glasses can compensate for some conditions, but in other cases, eye surgery may be required. Generally, eye surgery can be classified into posterior eye surgery such as vitreoretinal surgery and anterior eye surgery such as cataract surgery. Vitreoretinal surgery can address many different eye conditions including, but not limited to, age-related macular degeneration, diabetic retinopathy, diabetic vitreous hemorrhage, macular hole, retinal detachment, epiretinal membrane, and cytomegalovirus retinitis.

[0003] In the case of cataract surgery, the surgical procedure may require an incision and insertion of tools into the eye to replace the cloudy natural lens with an intraocular lens (IOL). A larger incision site can result in a longer postoperative healing time. To shorten this healing time, typical surgical procedures have shifted to making an incision approximately 2 millimeters in size inside the eye. While this smaller incision size can shorten the postoperative healing time, as the incision size continues to decrease, problems such as the size and functionality of the insertion tool may arise. Usually, the insertion tool can be preloaded with an IOL that can be inserted into the patient's eye when the cloudy natural lens is removed. The insertion tool may include a plunger for pushing the IOL out of the nozzle of the insertion tool. The plunger may have additional functions such as pushing in by a tactile part and folding the IOL. When the incision is made, the insertion tool can be inserted into the eye through the incision, and the folded IOL can be dispensed into the eye by the operation of the plunger. As the incision site shrinks, the size of the nozzle of the insertion tool can correspondingly decrease.

Summary of the Invention

Means for Solving the Problems

[0004] In exemplary embodiments, this disclosure relates to a tactile optical control system. The tactile control system may include a housing comprising a bore and a cavity located on a first surface of the housing. The cavity may include a first end portion, a second end portion and a central portion, and the cavity provides access to the bore through the first surface of the housing. The tactile control system may include an arm coupled to the housing. The tactile control system may include an edge roller coupled to the housing.

[0005] In another exemplary embodiment, the disclosure covers an insertion tool. The insertion tool may include a drive system, the drive system including a body. The insertion tool may further include a plunger at least partially positioned on the drive system. The insertion tool may further include a nozzle. The insertion tool may further include a tactile optical control system positioned between the drive system and the body. The tactile optical control system may include a housing including a bore and a cavity positioned on a first surface of the housing. The cavity may include a first end, a second end and a central portion, and the cavity provides access to the bore through the first surface of the housing. The tactile control system may include an arm coupled to the housing. The tactile control system may include an edge roller coupled to the housing.

[0006] In yet another exemplary embodiment, the disclosure relates to a method for delivering an intraocular lens. The method may include rotating a pair of arms such that each arm engages with a corresponding tactile extension of the intraocular lens, thereby moving the tactile extension up an inclined surface and onto the optical portion of the intraocular lens. The method may further include pivoting a pair of edge rollers that engage with the edge of the intraocular lens to fold the optical portion and move the intraocular lens to align with a bore. The bore may extend from a first end of the housing to a cavity formed on a first surface of the housing in which the intraocular lens is positioned. The method may further include acting on a drive system to distribute the intraocular lens from the bore through a nozzle and into the eye, the nozzle being coupled to the housing.

[0007] Different embodiments may include one or more of the following features: The bore may have a U-shaped cross-section and include a first portion extending from a first end of the housing to the central portion of the cavity. The bore may have a smaller cross-section than the first portion and include a second portion extending from the central portion of the cavity to a second end of the housing. The tactile-optical-management system may further include an intraocular lens disposed within the cavity, the intraocular lens including an optical portion and a tactile extension extending from the optical portion. One end of the tactile extension extends from the optical portion onto the first end. The other end of the tactile extension extends from the optical portion onto the second end. The first and second ends may each include an end wall, a raised platform adjacent to the end wall for supporting one of the arms, a portion adjacent to the raised platform for supporting the tactile extension of the intraocular lens, and an inclined surface adjacent to that portion. The arm may include a pair of arms, one of which is positioned at the first end and the other at the second end. The arm may include a first portion, a second portion joined to the first portion at a bend, a pin extending from the first portion, and a tab extending from the second portion. Rotating the arm may include applying an external force to the tabs extending from each of the arms. The arms may be rotatable around each of the first portions. The edge roller may include a pair of edge rollers, each of which is positioned on an opposing platform formed on either side of the central portion of the cavity. The edge roller may include a slot formed on the first surface for receiving the edge of the optical portion of the intraocular lens, a bore formed adjacent to the slot, and a tab extending from the second surface opposite the first surface, the tab being received in a slot formed in the side wall of the housing. Swiveling the edge rollers may involve applying an external force to the tabs extending from each edge roller to cause each edge roller to swivel in an arc. The plunger of the insertion tool may be operable to engage with the intraocular lens when the drive system is activated and the intraocular lens is distributed from the nozzle. The drive system of the insertion tool may include a lever and a pneumatic system.

[0011] For the purpose of facilitating understanding of the principles of this disclosure, the implementations shown in the drawings will be referred to and described here using specific language. Nevertheless, it will be understood that no limitation is intended on the scope of the disclosure. Any alternative and further modifications to the devices, apparatus, and methods described, as well as any further applications of the principles of this disclosure, are fully assumed to be as would ordinarily conceivable to a person skilled in the art to which this disclosure relates. In particular, features, components, and / or steps described with reference to one or more implementations are fully assumed to be able to be combined with features, components, and / or steps described with reference to other implementations of this disclosure. For simplicity, in some examples, the same reference numeral may be used throughout the drawings to refer to the same or similar parts.

[0012] The exemplary embodiments described herein generally relate to ophthalmic surgery. More specifically, the exemplary embodiments generally relate to systems, methods, and devices for inserting an intraocular lens ("IOL") into the eye. Embodiments may include an insertion tool for preparing and delivering the IOL into the patient's eye, including a plunger, a nozzle, and a tactile optics management system. In some embodiments, the tactile optics management system can fold the IOL assembly and push in one or more tactile parts of the IOL assembly. The tactile parts extend from the optics of the IOL and stabilize the IOL when placed in the capsule bag of the eye. After the IOL is prepared, the plunger pushes the IOL out of the nozzle through the insertion tool.

[0013] Figure 1 shows a schematic diagram of the insertion tool 100. In some embodiments, the insertion tool 100 may include a drive system 102, a plunger 104, a tactile optics management system (replaceable, called “HOMS”) 106, and a nozzle 108. The drive system 102 may be any combination of systems or components that can operate 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 that can operate to advance the plunger 104 from the insertion tool 100, partially advance it, or drive it to fully deliver the IOL. 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 powered, for example, electrically, mechanically, hydraulically, pneumatically, a combination thereof, or by some other means. In response to the drive system 102, the plunger 104 moves through the HOMS 106. The HOMS106 may be positioned between the drive system 102 and the nozzle 108. In alternative embodiments, the HOMS106 may be positioned at other locations within the insertion tool 100. In some embodiments, the HOMS106 may include the IOL110 in an unfolded position.

[0014] The drive system 102 may be any system, component, or group of components that can operate to advance the IOL 110 through the insertion tool 100. For example, the drive system 102 may include a plunger schematically shown as plunger 104 in Figure 1, which engages with the IOL 110 positioned within the insertion tool 100 and is operable to advance the IOL 110 within the insertion tool 100. In some examples, the plunger 104 is operable to eject the IOL 110 from the insertion tool 100. In some embodiments, the drive system 102 may be a manually driven system; that is, in some embodiments, a user applies force to operate the drive system 102. An exemplary drive system 102 includes a plunger 104 that can be directly or indirectly manually engaged by a user to push the plunger 104 through the insertion tool 100. As it moves forward, the plunger 104 engages with the IOL 110, advancing the IOL 110 through the insertion tool 100, which may also include ejecting the IOL 110 from the insertion tool 10. A non-limiting example of a manual IOL insertion tool is described in U.S. Patent Application Publication 2016 / 0256316, the entire contents of which are incorporated herein by reference. According to other implementations, the drive system 102 may be an automated system. Examples of automated drive systems are described in U.S. Patent Nos. 8,808,308, 8,308,736 and 8,480,555, the entire contents of which are incorporated herein by reference. Furthermore, other automated drive systems within the scope of this disclosure are described in U.S. Patent No. 8,998,983 and U.S. Patent Application Publication 2017 / 0119522, the entire contents of which are incorporated herein by reference. While exemplary drive systems are provided as examples, these systems are not intended to be limiting. Rather, any components, groups of components, systems, devices, mechanisms, or combinations thereof that can operate to propel the IOL110 forward are within the scope of this disclosure.

[0015] As shown in FIG. 1, the IOL 110 is a single-piece IOL that includes an optical portion 114 and haptic extensions 112 that extend from opposite sides of the optical portion 114. For example, in the exemplary IOL 110 shown in FIG. 1, the haptic extensions 112 are disposed 180° relative to each other along the outer periphery of the optical portion 114. However, other types of IOLs are also within the scope of the present disclosure. For example, a multi-piece IOL in which the optical portion 114 and one or more haptic extensions 112 are separate components may also be used.

[0016] The IOL 110 may have a shape similar to the shape of the natural crystalline lens of an eye (e.g., the eye 200 shown in FIG. 2A). The IOL 110 can be made from many materials including, but not limited to, silicone, acrylic, and / or combinations thereof. Other materials are also contemplated. The haptic extensions 112 extend from the periphery of the optical portion 114 and function to stabilize the IOL 110 when it is disposed within the eye.

[0017] In some examples, the HOMS 106 can be actuated to push the haptic extensions 112 onto the optical portion 114 and fold the optical portion 114. For example, the HOMS 106 can operate to fold the haptic extensions 112 onto the optical portion 114 and fold the optical portion 114 over or around the folded haptic extensions 112. The IOL 110 is shown in a folded configuration at 116. The folded IOL 116 includes one or more haptic extensions 112 folded with respect to the optical portion 114 and, in some examples, may include the optical portion 114 folded with respect to one or more haptic extensions 112. The plunger 104 can advance through the HOMS 106 when the HOMS 106 folds the IOL 110. When 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 can push the folded IOL 116 into and through the nozzle 108.

[0018] Figure 2A shows an eye 200 of a patient undergoing surgery using an insertion tool 100. As shown, the insertion tool 100 distributes the folded IOL 116 into the patient's eye 200. In some embodiments, the incision 202 is made in the eye 200, for example, by a surgeon. For example, in some instances, the incision 202 can be made through the sclera 204 of the eye 200. In other examples, the incision can be formed in the cornea 209 of the eye 200. The incision 202 can be sized to allow insertion of a portion of the insertion tool 100 to deliver the folded IOL 116 into the capsular bag 208. For example, in some instances, the length of the incision 202 can be less than about 2000 microns (2 millimeters). In other examples, the incision 202 can have a length of about 0 microns to about 500 microns, about 500 microns to about 1000 microns, about 1000 microns to about 1500 microns, or about 1500 microns to about 2000 microns.

[0019] After the incision 202 is made, the insertion tool 100 is inserted through the incision into the interior 206 of the eye 200. The insertion tool 100 is actuated to distribute the folded IOL 116 into the capsular bag 208 of the eye 200. Once distributed, the folded IOL 116 returns to its initial unfolded state, and as shown in Figure 2B, the IOL 110 is placed within the capsular bag 208 of the eye 200. The capsular bag 208 holds the IOL 110 within the eye 200 in a relationship to the eye 200 such that the optical portion 114 refracts light directed towards the retina (not shown). The haptic extension 112 of the IOL 110 engages with the capsular bag 208 to secure the IOL 110 therein. After distributing the IOL 110 into the capsular bag 208, the insertion tool 100 is removed from the eye 200 through the incision 202, allowing the eye 200 to heal over a period of time.

[0020] Figures 3–5 show an exemplary insertion tool 100 capable of operating to deliver an IOL into the eye. As illustrated, the insertion tool 100 includes a drive system 102, a tactile optical system control unit 106, and a nozzle 108. The insertion tool 100 may also include a plunger, which may be similar to the plunger 104 shown in Figure 1. In some examples, the plunger can be operated to advance an IOL, which may be similar to, for example, the IOL 110 shown in Figure 1, within the insertion tool 100, and in some examples to dispense the IOL 110 from the insertion tool 100.

[0021] Referring to Figure 3, the drive system 102 includes a body 302 and a lever 304 which can be rotatably coupled to the body 302. The nozzle 108 is coupled to the distal end 308 of the body 302. The HOMS 106 is positioned between the body 302 and the nozzle 108. In some examples, the nozzle 108 may be integrally connected to the body 302. In other examples, the nozzle 108 may be separated from the body 302 and coupled to the body 302 via an interlock relationship. In some examples, the HOMS 106 and the nozzle 108 may be integrally formed. In other examples, the HOMS 106, the nozzle 108, and the body 302 may be integrally formed.

[0022] In some examples, the body 302 may have a slender, elongated shape. In some examples, the body 302 may have a first portion 310 and a second portion 312. In some examples, 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 apertures 314. A plurality of tabs 316 formed on the second portion 312 may be received into the apertures 314 to join the first portion 310 and the second portion 312. The tabs 316 may form interlocks that fit with the apertures 314. However, the structure of the body 302 of the exemplary insertion tool 100 shown in Figures 3 to 5 is merely a non-limiting example. In some examples, the body 302 may be a single, integrated part. In some examples, the body 302 may include one or more cylindrical parts. Furthermore, the body 302 may be constructed from any number of components in any desired manner.

[0023] Continuing to refer to Figures 3 to 5, the body 302 also includes reliefs 318, 319, and 320. Relieves 318, 319, and 320 are shallow recesses formed in the body 302 to accommodate, for example, one or more fingers of the user. One or more of the reliefs 318, 319, and 320 may include a textured surface 322 that can provide the user with improved grip and control over the insertion tool 100. As shown in Figures 3 and 5, the relief 318 may include the textured surface 322. However, its scope is not limited in this way. Rather, any or all of the reliefs 318, 319, and 320 may include the textured surface 322, or none of them may include it. Similarly, the lever 304 may also include a textured surface 324. However, in some examples, the lever 304 may not include a textured surface.

[0024] Referring to Figure 3, the nozzle 108 includes a distal tip 326 that defines the opening 328. The nozzle 108 also includes a flared portion or wound guard 330. The distal tip 326 may be adapted to be inserted into an incision formed in the eye, such as the incision 202 shown in Figure 2, in order to deliver a folded IOL therein. The wound guard 330 may include an end face 332 that is operable to contact the outer surface in order to limit the depth to which the distal tip 326 enters the eye. In some embodiments, the wound guard 330 may be omitted.

[0025] In some embodiments, the insertion tool 100 may be preloaded. That is, the insertion tool 100 may contain an IOL placed inside it when provided to the end user. In some examples, the IOL may be placed inside the insertion tool 100 in an unfolded state, ready for delivery to the patient. Preloading the IOL into the insertion tool 100 reduces the number of steps the user must perform before delivering the IOL to the patient. For example, a preloaded insertion tool 100 eliminates any steps that the user would otherwise have to perform to load the IOL into the insertion tool 100. Reducing the number of steps can reduce errors and risks associated with delivering the IOL to the patient. Furthermore, the amount of time required for IOL delivery can also be reduced. In some embodiments, the IOL may be preloaded inside the HOMS 106.

[0026] Figure 6 shows an enlarged view of an exemplary insertion tool 100 equipped with a tactile optical unit management system 106. As previously mentioned, the HOMS 106 is operable to fold the IOL (e.g., the IOL 110 shown in Figure 1). For example, in some examples, the HOMS 106 may be operable to fold the IOL 110 from a stress-free state to a fully folded configuration, for example, as shown in Figure 1. During folding, the HOMS 106 can push or fold the tactile extension 112 onto the optical unit 114 of the IOL 110, and, as shown in Figure 1, for example, fold the edge of the optical unit 114 onto the pushed tactile extension 112 to capture the tactile extension 112, thereby positioning the IOL 110 in the folded configuration.

[0027] For example, as shown in Figures 3 to 6, the HOMS 106 is sized to match the size of the insertion tool 100. That is, the HOMS 106 has a compact size that avoids or limits the amount of obstruction to the surgeon's field of view while the IOL is being inserted into the eye. However, the scope of this disclosure is not limited in this way. Rather, in some examples, the size and / or shape of the tactile optics management system can be selected to be any desired size or shape. Furthermore, although the HOMS 106 is shown positioned at the distal end of the insertion tool 100, the tactile optics management system 106 can be positioned within the insertion tool 100 or at any location along the insertion tool 100. In some embodiments, the HOMS 106 may be positioned between the nozzle 108 and the drive system 102.

[0028] In the examples shown in Figures 3 to 6, the HOMS 106 is positioned between the distal end 308 of the body 302 and the nozzle 108. In some examples, the HOMS 106 may be detachably coupled to the nozzle 108 and / or the drive system 102. For example, the HOMS 106 may be detachably coupled to the body 302 using fasteners or adhesives. In yet other configurations, the HOMS 106 may be coupled to the body 302 by snap-fit ​​engagements or any other desired connection method. Exemplary fasteners, though not limited to them, may include nuts and bolts, washers, screws, pins, sockets, rods and studs, hinges, and / or any combination thereof.

[0029] Figure 7 shows an exemplary tactile optical unit management system 106. In the illustrated example, the HOMS 106 includes a housing 702, an arm 704, and an edge roller 706. The housing 702 forms a cavity 707 that receives the IOL 110. As shown, the IOL 110 is located within the cavity 707 formed in the housing 702.

[0030] The arms 704 are swivelably mounted in the housing 702 and pivot around their respective axes 709. In some examples, the axis 709 may be parallel to the optical axis 690 of the optical unit 114. In other configurations, the axis 709 may have other orientations relative to the optical unit 114. The edge rollers 706 are swivelably received within the housing 702. The edge rollers 706 pivot on a pin (not shown) around an axis 715 (for example, shown in Figure 10). Each of the arms 704 engages with one of the tactile extensions 112. When activated (described in more detail below), the arms 704 fold the tactile extensions 112 over the optical unit 114. The edge rollers 706 receive the lateral edges of the optical unit 114 into grooves formed in each of the edge rollers 706, as described in more detail below. When activated, the edge roller 706 pivots inward around each axis (e.g., axis 1005 in Figure 10) so that the optical unit 114 folds into a U-shape. In some examples, the arm 704 is initially operated to fold the tactile extension 112 onto the optical unit 114, and the edge roller 706 is operated after the arm 704 has moved so that the optical unit 114 folds and captures the tactile extension 112, thereby positioning the IOL 110 into a folded configuration such as the folded IOL 116 shown in Figure 1.

[0031] Each of the arms 704 includes a tab 717 extending from it. The tab 717 can be used to rotate the arm 704 around the axis 709. In some examples, a user can actuate the arm 704 by engaging the tab 717. In other examples, a device, mechanism, or system may be used to actuate the arm 704. Another exemplary tactile optical system in which an exemplary cam device is used to actuate the arms and other components of an exemplary tactile optical system is described in detail below.

[0032] Referring further to Figure 9, a perspective view of one arm 704 is shown. Multiple arms 704 may exist. The arm 704 may be made from any suitable material. Suitable materials may include, but are not limited to, metals, nonmetals, polymers, ceramics and / or combinations thereof. The arm 704 may be of any suitable size, height and / or shape. Suitable shapes may include, but are not limited to, cross-sectional shapes such as circular, elliptical, triangular, rectangular, square, hexagonal and / or combinations thereof.

[0033] In the illustrated embodiment, the arm 704 includes a first portion 710 and a second portion 712. The first portion 710 and the second portion 712 are joined at a bend 714. A pin 716 extends from the first portion 710. The pin 716 is received in a bore formed in the housing 702 (e.g., bore 826 shown in Figure 8), and the arm 704 pivots around the pin 716. A tab 717 extends from the second portion 712 on the side of the arm opposite the pin 716. As described above, the tab 717 can be used to actuate the arm 704, causing the arm 704 to pivot around the pin 716. Any suitable technique can be used to apply an external force to the tab 717. In the embodiment, an operator (not shown) can grasp and rotate the tab 717, thereby rotating the entire arm 704 around the pin 716. The arm 704 also includes a projection 718 extending from a second portion 712 on the side opposite to the tab 717. The projection 718 is operable to engage with the tactile extension 112 of the IOL 110 in order to fold the tactile extension 112 during operation of the HOMS 106.

[0034] Referring further to Figure 10, a perspective view of the edge roller 706 is shown. Multiple edge rollers 706 may exist. The edge roller 706 may be made from any suitable material. Suitable materials may include, but are not limited to, metals, nonmetals, polymers, ceramics and / or combinations thereof. The edge roller 706 may be of any suitable size, height and / or shape. In the illustrated embodiment, the edge roller 706 includes a slot 1000 formed in the first surface 1002. The slot 1000 is adapted to receive a portion of the optical section of the IOL, such as the optical section 114 of the IOL 110. The edge roller 706 also includes a bore 1004 formed adjacent to the slot 1000. When installed in the housing 702, the bore 1004 aligns with a bore 838 formed in the housing 702 (most commonly seen, for example, in Figure 8). Although not shown, pins (not shown) may extend through bores 1004 and 838 aligned to secure the edge roller 706 to the housing 702 so that the edge roller 706 pivots around axis 715. A tab 1006 extends from a side surface 1008 facing the first surface 1002. The tab 1006 may be used to rotate the edge roller 706 around bore 1004. In some examples, a user may engage the tab 1006 to actuate the edge roller 706, thereby pivoting the edge roller 706 around bore 1004 in the direction of arrow 1010. In other examples, a device, mechanism, or system may be used to actuate the edge roller 706. An exemplary cam device is described in detail below in relation to another exemplary tactile optics control system used to actuate the arms and other components of an exemplary tactile optics control system.

[0035] Referring further to Figure 8, the housing 702 is shown in more detail. The housing 702 may be made from materials such as metals, nonmetals, polymers, ceramics and / or combinations thereof. The housing 702 may have any size and / or shape. For example, but not limited to, the housing 702 may be formed such that all or part of the housing 702 has a cross-sectional shape that is circular, elliptical, triangular, rectangular, square, hexagonal and / or combinations thereof. In other embodiments, all or part of the housing 702 may have a rectangular cross-sectional shape.

[0036] 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., plunger 104 shown in Figure 1) advances and engages with the IOL 110, driving the IOL 110 through the HOMS 106. In some implementations, the plunger continues to drive the IOL 110 through the nozzle of the insertion tool and ejects the IOL 110 from the insertion tool. In the example shown in Figure 8, the first portion 801 of the bore 800 that extends distally from a cavity 707 formed within the housing 702 has a U-shaped cross-section. However, the scope of this disclosure is not limited thereto. In other implementations, the bore 800 may have a cross-sectional shape that is circular, elliptical, rectangular, square, triangular, polygonal, or any other cross-sectional shape. The second portion 803 of the bore 800 has a smaller cross-sectional size than the first portion 801. Furthermore, the cross-sectional shape of the second portion 803 differs from that of the first portion 801. In particular, as shown in Figure 8, 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 this disclosure. Furthermore, in some examples, the cross-sectional size and shape of the first portion 801 and the second portion 803 may be the same. The cross-sectional size of the second portion 803 can be smaller than that of the first portion 801, as a plunger can generally be passed through the second portion 803, which is smaller in size than the folded IOL.

[0037] The cavity 707 is formed in the first surface 806 of the housing 702 and receives the IOL 110 therein. In some embodiments, there may be one or more parts of material 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 illustrated embodiment, the first surface 806 may be formed on any suitable side of the housing 702. In the illustrated embodiment, the first surface 806 with the cavity 707 may be the top surface of the housing 702.

[0038] The cavity 707 includes a first end 808, a second end 810, and a central portion 812. The central portion 812 is deeper than the first end 808 and the second end 810 in that the central portion 812 extends a longer distance within the housing 702. The IOL 110 is received within the cavity 707 of the housing 702 so that the optical section 114 of the IOL 110 is suspended on the central portion 812. The base 814 of the central portion 812 may coincide with the base of the bore 800. Thus, in the illustrated example, the base 814 has a U-shaped cross-sectional shape. The central portion 812 also includes a platform 816 that is laterally offset from the base 814. One of the platforms 816 is obscured by part of the housing 702 in Figure 8. The platform 816 is raised relative to the base 814 but recessed below the first end 808 and the second end 810. Slot 818 is formed in the side wall 820. Slot 818 is fitted to receive the tab 1006 of the edge roller 706.

[0039] Each of the first end 808 and the second end 810 includes an inclined surface 822, a raised platform 824, a bore 826 formed in the raised platform 824, and an end wall 828. The end wall 828 has an arc shape that matches the curvature of the tactile extension 112 of the IOL 110. The curvature of the end wall 828 helps to hold the IOL 110 in a desired direction within the housing 702. In other configurations, the end wall 828 may have a different shape. For example, the shape of the end wall 828 is a non-arc shape that conforms to a non-arc shape of the tactile extension. In yet another configuration, the end wall 828 may have a shape that does not correspond to or otherwise match the shape of the tactile extension 112 of the IOL 110. The end wall 828, in combination with the raised platform 824, forms a recess 830. When the arm 704 is not in operation, the arm 704 can be at least partially received on the raised platform 824.

[0040] The portions 832 of the first end 808 and the second end 810, positioned between the end wall 828 and the inclined surface 822, define recesses that receive the tactile portion of the IOL 110 (e.g., the tactile extension 112 of the IOL 110 shown in Figure 7) when the IOL 110 is in a stress-free state. The portions 832 assist in positioning the IOL 110, which is located within the cavity 707 of the housing 702, in a desired orientation. As shown, the portion 832 may be arc-shaped, but the portion 832 may be formed in other ways as needed for a particular application. The arm 704 is supported by a raised platform 824, and the pin 716 of the arm 704 is received within the bore 826. As described above, the arm 704 is pivotable around the pin 716 within the bore 826. The inclined surface 822 operates to lift the tactile portion of the IOL above the optical portion when the tactile portion is displaced by the arm 704. The inclined surface 822 can be positioned at any suitable location on the respective first end 808 and second end 810 and can be set to any suitable angle. As shown in Figure 8, the inclined surface 822 includes a groove 834 that matches the path along which the projection 718 of the arm 704 travels as the arm 704 pivots on the pin 716 around the axis 709. As further illustrated, the first end 840 of the inclined surface 822 can be aligned tangentially with the central portion 812 of the cavity 707. The second end 842 of the inclined surface 822 can be adjacent to portion 832.

[0041] The edge roller 706 is received in the central portion 812 of the cavity 707 on the platform 816. The bore 838 of the housing 702 may be aligned with the bore 713 of the edge roller 706. As described above, a pin (not shown) extends through the aligned bore 1004 of the edge roller 706 and the bore 713 formed in the housing 702, so that the edge roller can pivot on the pin around the axis 715. The tab 1006 of the edge roller 706 is received in the slot 818. In the non-working position, the tab 1006 is on the closed end 836 of the slot 818. In the non-working position, the tab 1006 of the edge roller 706 may be perpendicular to the side wall 820. However, in other implementations, the tab 1006 may be positioned in other orientations relative to the side wall 820. The lateral edge of the IOL installed in the cavity 707 is received into a slot 1000 formed in the edge roller 706 by the edge roller 706 installed in the housing 702.

[0042] Here, with reference to Figures 7 and 11-13, the operation of the tactile control system 106 in operation will be described in more detail. As shown in Figure 7, the operator can place the IOL 110 within the housing 702. In the illustrated embodiment, the IOL 110 can be placed within the cavity 707 for preloading into the tactile optical control system 106. The IOL 110 may be placed within the cavity 707 in a relaxed or initial state with the tactile extension 112 extending from the optical unit 114. The tactile extension 112 may be placed on portion 832 of the cavity 707. At least a portion of the edge 719 of the IOL 110 may be held by the edge roller 706. As shown, at least a portion of the edge 719 of the IOL 110 may be placed within the slot 1000 of the edge roller 706. In the illustrated embodiment, the edge roller 706 can secure the IOL 110 on the central portion 812 of the cavity 707 (for example, as shown in Figure 8).

[0043] Figure 11 shows the operation of the arm 704 for moving the tactile extension 112 onto the optical section 114 of the IOL 110 according to this embodiment. As previously mentioned, the embodiment may include applying force to the tab 717 of the arm 704 to rotate the arm 704 around the first portion 710 of the arm 704. As the force rotates and moves the arm 704, the arm 704 can engage with the tactile extension 112 of the IOL 110 and move them onto the inclined surface 822. In the embodiment, the arm 704 can fold the tactile extension 112 above and above the optical section 114. In the illustrated embodiment, the second portion 712 of the arm 704 can engage with the tactile extension 112 and move the tactile extension 112 along the inclined surface 822 of the housing 702. As the tactile extension 112 moves along the inclined surface 822, the tactile extension 112 moves upward, thereby allowing it to move away from the inclined surface 822 and onto the optical section 114 of the IOL 110.

[0044] Figure 12 shows the operation of the edge roller 706 for folding the IOL 110 according to this embodiment. As previously mentioned, the embodiment may include applying force to the tabs 1106 of the edge roller 706 to pivot the edge roller 706 in arcs 1200. By pivoting the edge roller 706 by force, the optical section 114 of the IOL 110 can be folded, so that the optical section 114 can be at least partially positioned in the slot 1000 of the edge roller 706 (see, for example, Figure 10). In addition, the pivoting of the edge roller 706 in arc 1200 can move the IOL 110 into the bore 800 formed in the housing 702.
