Technical field

The present disclosure relates to a guide lens for implantation into the eye.

Background of the Invention Surgical procedures for treating cataracts, which are commonly employed today, include implanting an intraocular lens (IOL) into the eye. In such procedures, the normal human lens opacified by cataracts is typically replaced by an IOL.

During the past 40 years, many breakthroughs in cataract surgery have yielded reliable surgical procedures that regularly produce desirable patient outcomes. Modern surgical techniques have also made surgery very safe when performed by a skilled physician.

Procedures can now also be considered surgical means to treat myopia, hyperopia, or astigmatism, as IOLs with the proper ability to provide optical correction can be inserted into the eye.

One of the remaining problems that need to be addressed is making post-operative long-distance vision more accurate than it is now (e.g., without glasses or contact lenses). This makes the lens surgery comparable to corneal surgery, as long as the uncorrected visual acuity is involved, performing general surgical cataract surgery or removal of a clear lens, or refractive surgery.

Recently, lenses have been developed to treat presbyopia. There are two types of focus and perspective control. Because light entering the eye has more than one focus, less than half of the light is focused at one time in a patient who has had a multifocal lens implanted, so problems related to photic rings, glare, blurred vision, and reduced contrast sensitivity . Many of these lenses had to be eaten out because of these problems. A perspective adjustable lens was also invented which is designed to move forward when contraction of the somatic muscles in the near field. The near vision by such a lens is not as good as that by the multifocal lens, but has no problems associated with the multifocal lens.

Two of the remaining problems that need to be addressed are making the post-operative distance vision more precise than it is now, and providing excellent naked distance, near, and medium vision by a single focus lens. This makes lens surgery comparable to corneal surgery as long as uncorrected visual acuity is involved, making general surgical cataract surgery or removal of a clear lens a safer, less complicated procedure than refractive surgery and corneal reconstruction.

The various embodiments described herein may be used to more accurately position the optics of the guide lens in a more consistently repeatable and predictable position along the optic or visual axis of the eye as compared to other lens designs (e.g., with the aid of glasses or contact lenses And a guide lens structure that makes post-operative uncorrected visual acuity more predictable.

The present disclosure describes a guide lens comprising, for example, a rigid support connected to a collapsible optic. Properly connecting optical parts that can be folded to the rigid support can prevent deformation of the support when receiving the action of an amygdala after transplantation into the empty lens capsule during cataract surgery. In the various embodiments described herein, two rigid supports of substantially the same length are designed to hold the lens optic substantially at a position along the optical or visual axis of the same eye as when it was placed into the lens capsule at the time of surgery. The lens may be designed to be slightly longer or shorter than the lens capsule and may be planar, curved, or refractive, and the support may, in some embodiments, be bolted to the lens optic forward or backward upon insertion into the lens capsule Having a fixed angle to the optic at the point of manufacture between 5 [deg.] And 40 [deg.].

In one of the embodiments of the perspective unconstrained lens described herein, the force of the acoustical roots may be insufficient to cause the optical portion to move, for example, forward. For example, various embodiments do not have any flexible connections (e.g., hinges, torsion bars, etc.) between the optic and the support that allow the optic portion to move relative to the support by movement of the embolus.

Many guide lenses have optics coupled to two or more flexible supports that serve to center and fix the lens in the empty lens capsule of the human lens. This support may be formed by two flexible loops.

Circular somatosensory inside the eye, part of the autonomic nervous system and active throughout life, is responsible for changing the focus of the eye. When a patient who has been implanted with a standard loop guide lens wants to see during the initial post-operative period after cataract surgery, the still-active amygdala will collide with the flexible loop and move it forward and backward, to the center and to the periphery, (E.g., in the longitudinal direction of the lens). This movement can displace the position of the lens in the lens capsule. Also during this period fibrosis occurs and the loops are not necessarily finally fixed in the recesses of the cyst that was located at the time of the operation. Instead, the loop can be secured somewhere, for example, between the recesses of the lens capsule and the optic. Changing the position of the support loop in the capsule also changes the position of the lens optic along the axis of the eye and can cause decentration and tilt of the optic. In some flexible loop designs, the loose flexible loops at the time of manufacture are significantly longer (e.g., up to 12 mm in length) than the 10 mm diameter of the lens capsule and may collide against the amygdala by collision through the lens capsule wall. The support can be easily deformed by the pressure and the pressure applied thereto during the initial post-operative period. Thus, the lens position is not where he was calculated and expected. As a result, uncorrected distance vision (for example, without glasses or contact lenses) and postoperative refraction were not predicted prior to surgery. In some cases, the loop of the lens is compressed to the center and placed either forward or rearward of the lens optic.

The various embodiments described herein may be used to more accurately position the optics of the guide lens in a more consistently repeatable and predictable position along the optic or visual axis of the eye as compared to other lens designs (e.g., with the aid of glasses or contact lenses And a guide lens structure that makes post-operative uncorrected visual acuity more predictable.

Perspective Uncontrolled  lens

For example, see the guidance implants shown in Figs. 1-4. The guiding implant comprises an opposed rigid support portion 1 (e.g., a plate support portion) having an optic portion 2, and optionally a flexible loop laterally extending portion 6 (e.g., an open loop) (see Figures 3 and 4) ). However, in Figures 4-8, only one of the two supports is shown in this view. The supporting portion 1 can be connected directly to the optical portion 2 (see FIGS. 1 and 2) or to the short and thick rigid extension 3 of the optical portion 2 (see FIGS. 3 to 8) (E.g., monolithic) at the point of time, or may be separately formed and connected together. The short extension 3 can be constructed from the same material as the optical portion 2. [ In addition, the short rigidity extension part 3 may be formed integrally with the optical part 2 or may be formed separately from the optical part 2. In order to facilitate the connection, a hole 8 is made through the rigid component of the support, through which the flexible component 103 or the rigid extension 3 can be fused during the manufacturing process 8). The short and thick rigidity extension 3 may be preferable to facilitate the connection between the optical portion 2 and the support portion 1 without encroaching the circumferential portion of the optical portion 2. [

The optical portion 2 may comprise a substantially transparent biocompatible flexible optical material such as acrylic, hydrogel, or silicone, and may comprise any of a variety of materials including, but not limited to, double convex, planar convex, concave / planar, toric, aspherical, , Multifocus, or any combination thereof. The optic portion 2 includes a progressive optic lens (not shown) that includes a gradient of increasing optical power, for example, providing a near vision in the lower hemisphere of the optic and providing a far vision in the upper hemisphere of the optic when implanted in the eye. Lt; / RTI > The optical portion 2 can be used in combination with the second optical portion in the eye.

The support 1 is rigid and can be designed to resist deformation from the action of the soma. In particular, the support can resist pressure applied longitudinally by the soma muscle without bending. Unlike the flexible supports conventionally used with perspective-adjustable lenses and perspective-adjustable lenses, the rigid support 1 facilitates centralization because the rigid support 1 is resistant to compression, and the optics along the axis of the eye Provides a more consistent location of wealth.

As shown in Figure 1, in some embodiments, the support 1 may comprise an open loop. Some supports 1 may comprise one or more closed loops. (See also Figures 6 to 9, which will be described in more detail below).

Fig. 1 shows a lens made, for example, from acrylic as a single piece, and the optical part 2 is continuous with a curved open-loop type rigid support part 1. Fig. As with all such lens designs, the lens may be planar, or the optic portion 2 may be bolted to the back or forward at the time of the surgery.

Figure 2 shows a lens made of one material (e.g., acrylic) with a rigid plate-like support structure 4 'and a small distal fusing finger 5.

Figure 3 schematically shows an embodiment of a support 1 having a single rigid longitudinal structure 11 and forming a T-shaped section with a flexible distal lateral extension 6, wherein the rigid longitudinal support < RTI ID = 0.0 > 11 are attached to the short and thick extensions 3 of the optical part 2 or connected to the optical part 2.

Figures 4 and 5 include a chassis 104 that includes two rigid struts / plates 101 and a proximal transverse connecting bar 102 between two struts / plates 101 (at the proximal end) (1). The chassis 104, which is embedded into the flexible optical material 103, has an external distal fusing finger 6 in Fig.

Figure 6 shows a further embodiment of the invention in which during the manufacturing process a knob (not shown) which is fixed in the optical part by fusion of the flexible material through the hole 8, is embedded proximal into the thick rigid extension 3 of the optical part 2, (1) comprising two rigid struts / plates (7) with a finger-like extension (6) with a major peripheral end (10) The two plates 7 are connected in a circle by a thin transverse crossbar 9. The two rigid struts / plates 7 and the transverse crossbar 9 form an open space in the longitudinal direction between the transverse crossbar 9 and the optical part 2. [

Figure 7 shows that the fixation into the lens capsule takes place by means of a strut / plate 7, a bar 9, and a thick, rigid extension 3 to form a distal thin connecting bar 9 for fiberizing through the fence- 6 except that the flexible fingers 6 are not achieved by fusion of the front and back caps above. The width of each strut may be between 1.0 mm and 3.0 mm so that the lens can be folded longitudinally to be inserted and inserted through an incision of 3.0 mm or less.

Figure 8 shows that two rigid closed loops 21 are provided on each lateral side 22 to provide two fenced spaces 22 or openings into which the lens catheter can enter into the fiber bag for fixing the lens support 1 in the lens capsule. Figure 1 shows a support 1 comprising a single plate 20 to be attached.

Figures 10, 11 and 12 illustrate possible side views of a lens that is bolted to the rear (Figure 10), bolted to the front (Figure 11), and may be planar (Figure 12). Figs. 10 and 11 illustrate bolt-like optics, respectively, rearward and forward with respect to the distal end of the support when implanted. Such a lens as shown in Fig. 10 may include a planar perspective adjustable lens as described herein, for example, bolted upon implantation. As described herein, such a lens shown in Fig. 10 may also be manufactured to deflect the support relative to the optic (e.g., forward) to increase the depth of focus. If the optical portion is bolted backwardly to the distal end of the support, the optic can potentially be in a position suitable for increasing the depth of focus.

In another embodiment, as shown in Fig. 12A, each support may be offset or fixed in a different direction so that the lens forms a stretched z-shape, for example, with respect to the optic, The second support portion can be displaced or fixed in the backward direction. Each support may be offset or fixed at an angle other than zero relative to the optic. The first support may be offset or fixed at a non-zero angle and the second support may be offset or fixed at a second non-zero angle different from the non-zero angle. When the supports are deflected in different directions, the optic can be tilted, as shown in Figure 12B, such that when the lens is positioned into the lens capsule, the upper hemisphere of the optic is deflected back and the lower hemisphere of the optic is deflected forward . In this configuration, when implanted in the eye, the upper hemisphere can be positioned to improve distance vision, and the lower hemisphere can be positioned to improve near vision. Such a deviation is described in U.S. Patent Application No. 13 / 953,605 (Attorney Docket No. CORD.005C1), published as U.S. Patent Application Publication No. 2014/0172093 A1, which is hereby incorporated by reference in its entirety.

Figure 13 shows a schematic view of a far-unregulated guide lens 100 in a lens capsule. A frontal lid 50 of the lens capsule, a posterior capsule 51 of the lens, and anterior capsule edge 52 of the lens in the lens capsule recess.

The lens described above is connected to a longitudinally rigid but transversely flexible rigid support 1 (e.g., a plate support) so that the lens can be compressed into the insertion device for insertion into the eye through an incision of 3.0 mm or less And is designed to have a sex optical part 2. The support 1 is sufficiently rigid to prevent bending in the longitudinal direction when subjected to the pressure exerted by the action of the soma and the fibrosis. The thin transverse connecting bar 9 of the chassis 104 is flexible to enable the lens to collapse and compress relative to the longitudinal axis when present.

In various embodiments, the overall length D of the lens 100 may be about 9.5 mm to about 14.0 mm when measured diagonally from the tips of the flanking side loops 6 on opposite sides of the lens 100. See, e.g., FIGS. 3 and 13. The diagonal distance D extends through the center of the optical portion 2. The longitudinal length L of the lens 100 (also shown in Figures 3 and 13) may be at least the average lens capsule diameter. For example, the longitudinal length of the lens 100 can be about 9.5 mm to about 12.0 mm, and the preferred length is about 10.5 mm in various embodiments, which is slightly longer than the average lens capsule diameter in some embodiments . When the length of the lens 100 is about 10.5 mm or less, the lens 100 does not deform the lens capsule and does not collide on the soma.

The supporting element 3 extending from the flexible optical part 2 is made rigid by its small length of less than 1 mm and by a thickness of more than 1 mm in some embodiments and is made of acrylic, silicone, or other inert flexible material And at least partially a rigid component of polyimide, acrylic, or other rigid material. The support 1 can be made rigid in the longitudinal direction, which is provided by the combination of the rigid material 104 embedded in the flexible material 103 in some embodiments. The rigid strut and / or plate 7 may be made of any of the derivatives of polyimide, ploren or nylon, PMMA, titanium, or other rigid or inert material, or rigid and / or rigid, to make the support 1 rigid in the longitudinal direction. And combinations of flexible materials.

In some embodiments, the guide lens may include at least one semi-rigid support (e.g., two, three, or more) and an optic. In some embodiments, the at least one semi-rigid support and the optic may comprise the same material (e.g., acrylic). In some embodiments, the guide lens may be monolithic or a single lens. The semi-rigid support and optic can be folded to insert the optic into the eye through a small incision. However, after insertion is restored to its shape, it is sufficiently resistant to withstand the pressure changes in the eye resulting from the contraction and relaxation of the amygdala and from the forces that occur during post-surgical fibrosis. The two semi-rigid supports may have the same length. The action of the amygdala and resistance to deformation by fibrosis keeps the lens optic at a position along the optical or visual axis of the eyeball that is substantially the same as when it was placed into the empty lens capsule at the time of surgery. The lens can be designed to be slightly longer or shorter than the lens capsule and the support (e.g., the distal end of the support) can be designed to be between about 5 degrees and about 40 degrees With a fixed angle at a point of manufacture between about 1 DEG and about 50 DEG, such as between about 5 DEG and about 20 DEG, between about 10 DEG and about 25 DEG, or between about 15 DEG and about 40 DEG, As shown in Fig. This will place the lens optic in the back position relative to the distal end of the support upon insertion into the lens capsule.

Various embodiments relate to a perspective non-regulating guide lens having an optic made of a single piece with the optic portion being displaced or bolted rearwardly relative to the distal end of the support, wherein the angle of deviation or bolt angle is the same on the optic / can do. The semi-rigid lens structure can resist longitudinal deformation by the amygdala and fibrosis, but it can be folded longitudinally to be inserted into the lens capsule of the eye through an incision of less than 4.0 mm.

The overall longitudinal length of the lens may be between about 9.5 mm and about 12 mm, which may be slightly longer than the lens capsule, and preferably about 10.5 mm. When the length of the lens 100 is about 10.5 mm or less, the lens 100 does not deform the lens capsule and does not collide on the soma.

Both semi-rigid supports can be of the same length. The diameter of the optic can be between 4.0 mm and 8 mm and has a thin central thickness of between about 0.2 mm and about 2.0 mm. Since the semi-rigid material is resistant to deformation by the amygdala and fibrosis, the support can not be significantly deformed, and therefore the lens optic is in the same postoperative position as at the time of surgery. Similarly, the orientation of the guide lens may be the same as before the operation, when the toric lens is implanted, along the axis of the eye and on the axis of rotation. This makes the predictability of the effective lens position (ELP) along the visual axis of the eye more precise, and therefore the naked eye vision is more predictable. The longitudinal length of the guide lens can be fixed before insertion into the eye, for example, the longitudinal length of the guide lens can be the same before and after surgery. However, the lens may have a thin flexible distal fingers, making the lateral diameter greater than the longitudinal diameter. These flexible fingers can be designed to fix the lens in the lens capsule and to prevent rotation of the lens when the toric optics portion is part of the lens design.

As described above, the longitudinal rigid support may comprise the same material as the flexible optical portion, and may be manufactured as a single piece. The semi-rigid support can be made more rigid by increasing its thickness and / or its width. Fusing may be accomplished using a continuous flexible loop (open or closed loop) with the lens body extending tangentially from the distal lateral face of the plate support design, or by creating an open space within the boundaries of the diameter of the support and / By a closed loop extending beyond the diameter of the part. The loop of semi-rigid material is flexible and compressible, but may be thin enough to be rigid enough to hold the length of the lens when subjected to force from the soma.

However, the various embodiments disclosed herein can solve the problems described above. See, for example, the guide implant shown in Fig. The guide implant comprises an opposed, forwardly biased, semi-rigid support 4 directly connected to the optic in flexural joint 4, with optical portion 2, and flexible loop laterally extending portion 6 (e.g., open loop) (1). In Figures 16-18, only one of the two halves of the lens is shown. The lens may have a double fold symmetry so that the other half is the same as shown. The short optical extensions 3 may comprise a junction 4 which is rigidly bent between the optical part 2 and the support part 1. The optical portion 2 and the support portion 1 may be composed of the same material (for example, acrylic). The short optical part extension 3 may be preferable for the support part 1 to facilitate the connection between the optical part 2 and the support part 1 without encroaching the circumferential part of the optical part 2. [ The guide lenses of Figs. 16-18 may include one of the features described with respect to Figs. 3, 6, and 8; Unlike such a view, the support 1 does not include a through hole through which the optical part extension 3 can extend, but this embodiment can also include a through hole. Similarly, one or a combination of features of the embodiment shown in one of Figs. 15-18 may be included in one of the other lenses shown in Figs. 1-7. For example, the flexural joint 4 shown in Figures 15-18 (and 9) can be included in Figures 1-2.

The lens may comprise a transparent biocompatible flexible optical material, such as acrylic, and the optic may be a double convex, a planar convex, a concave / planar, a toric, an aspherical, a spherical, a fresnel, a multifocal, . The optic portion 2 includes a progressive optic lens (not shown) that includes a gradient of increasing optical power, for example, providing near vision within the lower hemisphere of the optic when implanted in the eye and providing a far vision within the upper hemisphere of the optic Lt; / RTI >

The support 1 is designed, at least in the longitudinal direction, to be semi-rigid and resistant to deformation by the action of the soma, or by fibrosis. Unlike the flexible supports traditionally used with perspective-adjustable lenses and perspective-adjustable lenses, the semi-rigid longitudinal support 1 is resistant to deformation due to the somatic muscle and fibrosis in the longitudinally semi- , Facilitating centering and providing a more consistent position of the optic along the axis of the eye.

In the embodiment of the guide lens described herein, when the total length of the lens 100 is measured diagonally across the lens from the tips 10 of the fixing flexible lateral loops 6 on opposite sides of the lens, About 9.5 mm to about 12.0 mm, and about 11.0 mm to about 14.0 mm. See, e.g., Fig. The side loops 6 may include an alignment member 10 (e.g., a circular or elliptical knob, one on each end of the fusing member) at the end of the side loops 6. The diagonal distance extends through the center of the optic. The longitudinal length L of the lens 100 (also shown in FIG. 3) may be at least the average lens capsule diameter. For example, the preferred longitudinal length may be about 10.5 mm. When the length of the lens 100 is about 10.5 mm or less, the lens 100 does not deform the lens capsule and does not collide on the soma.

The short optical extensions 3 extending from the flexible optic can, in some embodiments, be made stiffer by its short length of less than 1 mm and its thickness.

As shown in Figure 18 (a), the support 1 comprises a lateral member 30 (or paddle as mentioned elsewhere herein) 30, and a lateral direction extending between the side extension members 30 A bar 9 may be provided. The support 1 may be wider than the optical portion 2 (e.g., the distance between the side extension members 30 on the opposite sides of the optic as compared to the width or diameter of the optic) The tip 31 of the endoscope 10 may be designed to be positioned rearward relative to the optic when implanted. Thus, the lateral member 30 can be more and more curved toward the tip 31. [ The support 1 can form a closed loop 12 (and an open area). The guide lens may comprise a short optical part extension 3 and there is a junction 4 which is bent across the optical part 2 and the support part 1 in a rigid manner. This bendable joint 4 allows the support to be deflected as an angle relative to the optic at the time of manufacture, as described herein. In some embodiments, the support 1 partially surrounds the optic beyond 180 DEG of the periphery of the optic. For example, a single support may surround at least 110 °, 120 °, 130 °, 140 °, 150 °, 160 °, 170 ° to 175 °, or 180 °, or any range between them, of the circumference of the optic .

As shown in Figure 18 (b), the support 1 may have a lateral member (or paddle) 30 having a distal arcuate outer edge that is parallel to the longitudinal length at proximal to the optic. The supporting portion 1 may be wider than the optical portion by having a finger-shaped flexible lateral extending portion 6. [ The lateral member 30 can be connected by a short optical part extension 3 and there is a junction 4 which is bent across the optical part 2 and the support part 1 with rigidity. In some embodiments, the support 1 partially surrounds the optical portion in excess of 180 degrees of the circumference of the optic. For example, a single support may surround at least 110 °, 120 °, 130 °, 140 °, 150 °, 160 °, 170 ° to 175 °, or 180 °, or any range between them, of the circumference of the optic .

Figures 9a-9d show a chassis 104 with two longitudinally extending rigid struts / plates 30 extending therefrom, two lateral extending closure loops 31, designed to fix and center the lens in the lens capsule And a flexible optical portion 2 having a rigid support 1 that includes a rigid support 1. A distal bar 39 extends between the two struts / plates 30 to create a central fenced open region 32. Thus, the various embodiments may include one, two, three, four, or more closed loops 31 (and open area 32), at least some of which may require settlement by fibrosis It can be facilitated. In some embodiments, the more central open area 32 is larger than any open area on each side of the central open area, as shown in Figures 9A-9D. The chassis 104 is partially embedded in the flexible material 43 of the optical portion. In various embodiments, the support 1 is offset relative to the optics 2. A line 107 showing the rigid flexure joint 4 in the proximal portion of the frame or chassis 104 indicates the deviation of the support 1 against the optical portion 2 as described herein. However, in other embodiments, the design shown in Figures 9A-9D does not require the support to be offset relative to the optic at the point of manufacture, and thus it is necessary to include the rigid curved junction 4 as shown none. The concave portion of the lens capsule 33 is shown as partially expanded to a radius of 11.5 mm.

Perspective Lens

Although certain embodiments have been described herein with respect to perspective unconstrained lenses, the supports may be used in a perspective adjustable lens, potentially in combination with a hinge or connecting bar.

Various embodiments of the support described herein, including but not limited to those shown in Figs. 6-9D, may be used in a perspective adjustable lens. Additional information regarding the connecting bar and perspective adjustable lens may be found in U. S. Patent Application Serial No. < RTI ID = 0.0 > U.S. Patent Application Publication No. 2014/0094909, filed on September 24, 2013 entitled " Accommodating Intraocular Lens & (Attorney Docket No. CORD.009P1), filed on September 24, 2013, entitled " ANTERIOR CAPSULE DEFLECTOR RIDGE, " (Attorney Docket No. CORD.010A), which is hereby incorporated by reference in its entirety for all purposes and should be considered a part of this specification.

Figs. 14A-14D illustrate an example of a perspective adjustable guide lens 200 having an optic 202 and opposing plate supports 214. Figs. The plate support 214 may include a frame 222 embedded within the flexible component 226. The frame 222 may include a through hole 230 through which the flexible component 226 may extend to secure the frame 222. The frame 222 may comprise polyimide, plrene, polymethylmethanilate (PMMA), titanium, or similar materials. The flexible component 226 may comprise silicon, hydrogel, acrylic, or similar materials. In some cases, the flexible components 226 and the optics 202 may be constructed from the same material, for example, acrylic.

As shown in FIG. 14A, the frame 222 may extend outwardly beyond the proximal and distal edges of the flexible component 226. The exposed edges of the frame 222 reduce the slippage of the perspective adjustable guide lens (AIOL) 200 during implantation to facilitate implantation in the correct position. The frame 222 may include a plurality of openings 238 (e.g., one, two, three, four, or more openings) at its distal portion. At least some of the openings 238 may be at least partially formed by a thin transverse bar 242 located at the distal end of the support 214. At least some of the openings 238 may extend beyond the distal edge of the flexible component 226 such that fibrosis can occur around the thinner transverse bar 242 and through the openings 238. Thus, as described above, the various embodiments may include one, two, three, four, or more closed loops (and open area 238) Can be easily fixed. In some embodiments, the more central open area 238 is larger than any open area on each side of the central open area, as shown in Figures 14A-14D.

The plate support 214 is configured such that the plate support 214 is substantially rigid in the longitudinal direction (e.g., parallel to the y axis) and substantially flexible in the transverse direction (e.g., parallel to the x axis) . The plate support 214 may be sufficiently flexible transversely to facilitate insertion of the AIOL into the eyeball and may be sufficiently rigid in the longitudinal direction to resist coronal muscle contraction, i.e., decentration in response to end-to-end compression.

The proximal portion of each plate support 214 may include opposing paddles 234 that at least partially surround the optic 202. In various embodiments, for example, the single support may be at least 160 [deg.], 170 [deg.] To 175 [deg.] Or 180 [deg.] Or any range between them, or possibly 110 [deg.], 120 °, 130 °, 140 °, or 150 ° to 160 °, 170 ° or 180 °, or any range between them. The lateral width measured between the outer lateral edges of the paddles 234 may be greater than the lateral diameter of the optical portion 202. [ The proximal portion of the paddle 234 may be spaced apart (e.g., separated) from the optical portion 202. Prior to implantation, the AIOL 202 may be fabricated substantially planar. When the AIOL 200 is implanted into the eye, the optics 202 is bolted backwardly to the distal end of the support, such that at least the proximal portion of the paddle 234 is posterior to the optic after implantation into the eye . The greater surface area of the paddle 234 may further increase the pressure behind the AIOL 200 which may facilitate movement of the optic 202 in the forward direction when the embolus is retracted Thereby increasing the pressure of the fluid in the vitreous cavity.

Each opposing paddle 234 may include at least a portion of the frame 222 and at least a portion of the flexible component 226. [ The portion of the frame 222 that forms the paddle 234 may be larger than the portion of the flexible component 226 that forms the paddle 234. [ The portion of the frame 222 that forms the paddle 234 may be wider and / or longer than the portion of the flexible component 226 that forms the paddle 234. 14A, within the paddle 234, the frame 222 extends laterally beyond the lateral edges of the flexible component 226 and extends proximal beyond the proximal edge of the flexible component 226 do.

Each plate support 214 may include a connection portion that may be connected to the optics portion 202. The connecting portion may include a connecting bar 210 (e.g., a torsion bar) extending sideways from the short accessory 206 and the short accessory 206, for example, the connecting bar 210 may include a short accessory 206 And may extend laterally from each opposed lateral side. Each support 214 may include a elongated slot 218 that defines a through hole that may be round with respect to the short attachment 206 and the connecting bar 210.

The thickness of the connecting bar 210 may be less than the thickness of the short attachment 206. The thickness of the connecting bar 210 can be reduced such that the connecting bar 210 can be stretched and / or rotated (e.g., twisted) to facilitate movement of the optical portion 202 relative to the support 214. Additional information regarding the connecting bar and perspective adjustable lens may be found in U. S. Patent Application Serial No. < RTI ID = 0.0 > U.S. Patent Application Publication No. 2014/0094909, filed on September 24, 2013 entitled " Accommodating Intraocular Lens & Can be found in patent application Ser. No. 14 / 035,821 (Attorney Docket No. CORD.009P1), which is incorporated herein by reference in its entirety and should be considered part of this specification.

Each support portion 214 may include one or more forward ridge protrusions 246 extending forward from the support portion 214. Exemplary ridge protrusions 246 are described in U.S. Patent Application Publication No. 14 / 035,813, Attorney Docket No. CORD.010A, which is hereby incorporated by reference in its entirety for all purposes and should be considered a part of this specification. The one or more front ridge protrusions 246 may at least partially traverse one or both paddles 234 of each support 214. 14A, a single front ridge protrusion 246 may extend from one paddle 234 to another paddle 234 of the same support 214, and thus may be arcuate in shape. In Figure 14A, the bright spots portion of the support 214 is a frame 222 that may include polyimide. The darker areas illustrate the portion of the flexible component 226, including, for example, silicon, that covers the frame 222. The darkest shaded area depicts a ridge protrusion 246 that may include a thicker area of the flexible material (e.g., silicon) that makes up the flexible component 226. In such an arrangement, the front ridge protrusion 246 may at least partially surround the elongated slot 218. [ The cross section of the ridge protrusion 246 is also shown in Figs. 14B and 14D. One or more anterior ridge protrusions may separate the AIOL 202 from the anterior capsule of the human lens capsule. FIG. 14C shows a frame 222 (dark black area), which may include, for example, polyimide.

Such perspective adjustable guide lenses may also have other features as described elsewhere herein.
