A lens configured for implantation into an eye of a human can include an optic including transparent material. The optic can have an anterior surface and a posterior surface. Each of the anterior surface and the posterior surface can have a surface vertex. The optic can have an optical axis through the surface vertices. The lens can also include at least one haptic disposed with respect to the optic to affix the optic in the eye when implanted therein. The anterior and posterior surfaces can include aspheric surfaces. The posterior surface can have an aspheric shape that comprises a biconic offset by perturbations comprising an aspheric higher order function of radial distance from the optical axis. The posterior surface can have an absolute value of ratio R.sub.x/R.sub.y between 0 and 100 and an absolute value of ratio k.sub.x/k.sub.y between 0 and 100.

An ophthalmological implant including an imaging optical element, and a haptic with a haptic root. Also, a corresponding method for producing an ophthalmological implant and a characterization system for identifying an ophthalmological implant for example an intraocular lens. The implant includes an unambiguous label and hence an unambiguous and reliable identification option. The label is not able to be mixed-up and is possible with minimal additional technical outlay. The implant includes a rotationally symmetric structural code of identification data of the ophthalmological implant arranged on the haptic root and/or the region of the haptic proximate the haptic root. Also, a method for producing an ophthalmological implant, in which the implant receives, directly during or after the forming, a rotationally symmetric structural code of identification data.

A capsular prosthesis is disclosed that is implanted to support posterior chamber placement of IOLs. The capsular prosthesis can be implanted to replace the capsule in situations where the patient's natural capsule has been rendered incapable of providing the structural support necessary to maintain proper centration of an IOL implanted therein. The prosthesis is surgically implanted into the eye by inserting the prosthesis into the eye through a primary incision. The prosthesis is secured to the sclera of the eye with at least two transscleral sutures to establish at least three points of contact between the sclera and the at least three apertures of the prosthesis. The at least two transscleral sutures support the sheet within a desired plane located within the posterior chamber, the plane containing a predetermined surgical axis passing through the center aperture. The IOL is inserted through the primary incision and optically captured on the prosthesis.

An accommodating intraocular lens device is provided. The accommodating intraocular lens device comprises a base assembly and a power lens. The base assembly comprises a first open end, a second end coupled to a base lens, and a haptic surrounding a central cavity. The haptic may comprise an outer periphery, an inner surface and a height between a first edge and a second edge. The power lens is configured to fit within the central cavity. The power lens may comprise a first side, a second side, a peripheral edge coupling the first and second sides, and a closed cavity configured to house a fluid. The first side of the power lens may be positioned at a predetermined distance from the first edge of the haptic.

The invention relates to an implant for implanting in and/or an eye using fixing means enabling improved fixing, in particular with respect to the natural variability of the anatomical conditions of the eye. According to the invention, the fixing means comprise at least one support element which can be mounted on a tissue structure in the direction traverse to the optical axis of the eye.

An intraocular lens (TOL) for implantation within a capsular bag of a patient's eye comprises an optical structure and a haptic structure. The optical structure comprises a planar member, a plano convex member, and a fluid optical element defined between the planar member and the plano convex member. The fluid optical element has an optical power. The haptic structure couples the planar member and the plano convex member together at a peripheral portion of the optical structure. The haptic structure comprises a fluid reservoir in fluid communication with the fluid optical element and a peripheral structure for interfacing to the lens capsule. Shape changes of the lens capsule cause one or more of volume or shape changes to the fluid optical element in correspondence to deformations in the planar member to modify the optical power of the fluid optical element.

The present disclosure relates to devices, systems, and methods for improving or optimizing peripheral vision. In particular, various IOL designs, as well as IOL implantation locations, are disclosed which improve or optimize peripheral vision.

An ophthalmic implant configured for peri-operative, intra-operative, or post-operative assembly and disassembly. Drug delivery devices may be implanted with an intraocular lens, and later removed and replaced with new drug delivery devices.

An eye-implantable electrowetting lens can be operated to control an overall optical power of an eye in which the device is implanted. A lens chamber of the electrowetting lens contains first and second fluids that are immiscible with each other and have different refractive indexes. By applying a voltage to electrodes of the lens, the optical power of the lens can be controlled by affecting the geometry of the interface between the fluids. To prevent fouling the surface due to folding or other manipulation of the lens during the insertion process, one or more surfaces within the lens chamber is highly underwater oleophobic.

Apparatus (20, 420) is provided that includes a retinal implant (40), configured for implantation on a retina (306) of a subject's eye (300) in an epi-retinal position; and an anchor (60, 460, 660) shaped to define (i) an anterior portion (70, 470, 670), (ii) a posterior portion (90, 490, 690) coupled to the retinal implant (40), and (iii) a middle portion (80, 480, 680) extending longitudinally between the anterior portion (70, 470, 670) and the posterior portion (90, 490, 690). The anchor (60, 460, 660) is configured to anchor the retinal implant (40) to the retina (306) such that when the retinal implant (40) is implanted on the retina (306), the anterior portion (70, 470, 670) of the anchor (60, 460, 660) is mounted against a ciliary sulcus (310) of the eye (300). Other embodiments are also described.
