Various embodiments also include accommodating intraocular lenses.

Abstract: For easy handling at placement of intra ocular lenses (IOLs) for cataract operations, these are equipped with helical haptics of memory materials circumferring the lens. Said haptics adhere to the rim of the lens as long as being cooled down to constriction temperature. On regaining body temperature the haptics expand and fit into the ridges of the eye's capsule sack. Accommodation then is achieved with constriction of the capsule sack by pressure transfer to the rim of the lens to form its shape, in multiplying it with some protrusion towards the pupil.

Abstract: An intraocular lens that is capable of being inserted through a micro-incision includes an optic having an anterior and a posterior surface and a plurality of projections extending from the anterior and posterior surfaces. The anterior and posterior surfaces include a recess. The optic is implanted such that a rim of the capsulorhexis is disposed in the recess such that the plurality of projections grip the capsular bag.

Abstract: An intraocular lens (IOL) having a posterior prolate aspheric surface structured to bend or flex in response to force applied to such surface due to flexing of ciliary body muscle. The flexible and bendable haptic portions of the IOL, integrated with the central optical portion along its perimeter, as sized to have the distal sides of the haptic portions installed in the capsular membrane of a natural lens of an eye or in a space between the root of the iris and ciliary muscle. The optical power of the IOL is gradually modifiable due to change of curvature of the posterior prolate aspheric surface within the eye.

Abstract: Systems, devices, and methods are presented for a prosthetic injectable intraocular lens. One or more silicone elastomeric patches located outside the optical path on the anterior side but away from the equator can be accessed by surgical needles in order to fill or adjust optically clear fluid within the lens. The fluid can be adjusted in order to set a base dioptric power of the lens and otherwise adjust a lens after its initial insertion. The elastomeric patches are sized so that they self-seal after a needle is withdrawn. A straight or stepped slit in the patch can allow a blunt needle to more easily access the interior of the lens.

Abstract: A method and related apparatus to treat a cataract where the cataractous lens is pierced and the resulting opening is mechanically maintained using a lens system device such as a pinhole device, expandable tubular leas, a stent or similar small diameter device, some of which are capable of supporting a secondary intraocular lens. The resulting passageway or lumen created in the cataractous lens allows visible light to better reach the retina, thus improving vision. This lens system device that can be placed into an in situ cataract provides for a much simpler surgical technique and reduces related pre and post operative procedures and potential complications. Intraocular lenses may also be used in concert with this invention. The apparatus and technique can be applied to humans as well as animals.

Abstract: A deformable intracapsular implant device for shaping an enucleated lens capsule sac for use in cataract procedures and refractive lensectomy procedures. In one embodiment, the intraocular implant devices rely on thin film shape memory alloys and combine with the post-phaco capsular sac to provide a biomimetic complex that can mimic the energy-absorbing and energy-releasing characteristics of a young accommodative lens capsule. In another embodiment, the capsular shaping body is combined with an adaptive optic. The peripheral capsular shaping body carries at least one fluid-filled interior chamber that communicates with a space in a adaptive optic portion that has a deformable lens surface. The flexing of the peripheral shaping body in response to zonular tensioning and de-tensioning provides an inventive adaptive optics mechanism wherein fluid media flows between the respective chambers “adapts” the optic to increase and decrease the power thereof.

Abstract: An intraocular lens (IOL) system includes an optic, a pair of haptics located on sides of the optic, and hinge portions at each of the optic haptic junctions. The hinge portions have stressed and non-stressed configurations. One or more restraining elements are provided to maintain the stressed state configuration of the hinge portion during implantation and during a post-operative period during which the capsular bag of the eye heals about the lens. The restraining elements are thereafter removable, preferably via a non-surgically invasive manner, e.g., via dissolution or laser light. Removal of the restraining elements allows anteriorization of the optic as the lens assumes a non-stressed configuration during accommodation. The ciliary body and lens may then interact in a manner substantially similar to the physiological interaction between the ciliary body and a healthy natural crystalline lens.

Abstract: A narrow profile, glare reducing, posterior chamber intraocular lens comprises an optic having an anterior surface and a posterior surface and an optical axis. The posterior surface is formed having two adjacent peri-axial, stepped imaging zones, the two imaging zones having the substantially the same optical power. A transition zone between the two imaging zones preferably has a surface of continuous curvature shaped to reduce direct glare from light incident on the transition zone in an individual's eye in which the intraocular lens is implanted by internal reflection of direct light incident on the transition zone. Attachment members joined to the optic position the intraocular lens in an eye with the optical axis of the optic generally aligned with the optical axis of the eye. In variations, the transition zones are formed at the optic edge to minimize direct and indirect in the eye of an individual wearing the intraocular lens.

Abstract: A deformable, artificial intraocular contact lens for implantation into the human eye to correct normal-vision problems. The lens may be positioned posteriorly from the iris, resting against the anterior surface of the posterior capsule's natural lens. Alternatively, the lens may be positioned in the anterior chamber of the eye. The implanted lens works in conjunction with the cornea and natural lens to provide proper vision, as a substitute for regular contact lens, spectacles, and radial keratotomy. The lens may be designed from a rigid or semi-rigid material. Due to the thinness of the structure, the lens may be rolled and inserted into the eye, minimizing both the length of the corneal incision and the stretching of the cornea.

Abstract: This patent represents a deformable artificial intraocular lens and method for implantation into the human eye. The lens is used for implantation after cataract surgery. The lens optic consists of one smooth optical surface. The second optical surface is a series of annular concentric rings. The extremely thin lens optic along with the thin haptic can be rolled, folded, or squeezed to pass through a small incision (<1.5 millimeters) in the cornea or sclera of the human eye.

Abstract: This patent represents a deformable artificial intraocular lens for implantation into the human eye. The lens is used for implantation after cataract surgery. The lens optic consists of one smooth optical surface. The second optical surface is a series of annular concentric rings. The rings allow the lens to have extremely thin edges, which reduce glare, halos, and distortion. The extremely thin lens optic along with the thin haptic can be rolled, folded, or squeezed to pass through a small incision (<1.5 millimeters) in the cornea or sclera of the human eye. This lens represents a breakthrough in removal of mass from the lens. The ultra thin lens and haptic design allows the lens to move in the eye providing accommodation for the patient. The lens and haptic design reduces the radial forces on the eye to the point where the naturally occurring pressures in the eye move the lens thus providing accommodation.

Abstract: A narrow profile, glare reducing, refractive mono-focal intraocular lens is described that comprises an optic having an anterior surface and a posterior surface and an optical axis. One of the anterior and posterior surfaces is formed having two adjacent peri-axial, stepped imaging zones, the two imaging zones having the substantially the same optical power that is preferably outside the −5 to +5 diopter range. A transition zone between the two imaging zones preferably has a continuously variable surface curvature that reduces both indirect glare (caused by light refraction) and direct glare (caused by light diffraction) in an individual's eye in which the intraocular lens is implanted. The transition zone surface may alternatively be continuously curved or variably curved to reduce direct glare and indirect glare, respectively. Attachment members joined to the optic position the intraocular lens in an eye with the optical axis of the optic generally aligned with the optical axis of the eye.

After insertion of the haptic into the eye, any type of lens may be attached, especially by use of cleats.

Abstract: A lens system for implantation in a human eye which makes it possible to restore accommodation. The lens system comprises one anterior lens (2) and a posterior lens (4), out of these two lenses one has positive and the other has negative lens power. Accommodation is achieved by varying the distance between the two lenses. This lens system can be made so as to generate large changes in optical power for small changes in position. It also allows the amount of change in optical power for any given amount of change in distance between the lenses to be selected relatively independently of the optical power of the overall lens system.

Abstract: An intraocular lens provides substantially increased depth of focus for accurate near and far vision with an optic much thinner than a natural lens, and the lens being rigid, vaulted posteriorly and adapted for posterior positioning in the capsular bag. The optic is positioned substantially farther from the cornea than a natural lens, so that a cone of light exiting the optic to impinge upon the retina is much smaller than a cone of light from a natural lens. Typically, the optic may be about 1.0 mm thick and its distance from the cornea 7.0-8.0 mm.
