Intraocular lens

A method of performing laser surgery in a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form an enclosed treatment pattern that is configured to form an enclosed capsulorhexis incision that includes a registration feature, and delivering the enclosed treatment pattern to target tissue in the patient's eye to form in an anterior lens capsule of the patient's eye the enclosed capsulorhexis incision that includes the registration feature. The registration feature is configured so that an edge of the target tissue formed by the enclosed capsulorhexis incision mates with an intraocular lens registration feature on an intraocular lens so as to rotationally register the intraocular lens relative to the registration feature.

Prosthetic capsular devices, systems, and methods

A prosthetic capsular device configured to be inserted in an eye after removal of a lens, in some embodiments, can comprise a housing structure comprising capable of containing an intraocular device and an equiconvex refractive surface. The housing structure can comprise an anterior portion comprising an anterior opening, a posterior portion comprising a posterior opening, and a continuous lateral portion between the anterior portion and the posterior portion.

Accommodating intraocular lens device

An accommodating intraocular lens (IOL) can be implanted either alone or as part of a two-part lens assembly. The IOL comprises an optic, a flexible membrane and a peripheral edge coupling the optic and the flexible membrane. The peripheral edge comprises an external circumferential surface having a height and a force transmitting area defined along a portion of the height of the external circumferential surface. A closed volume spaces apart the optic and the flexible membrane. The optic is axially displaced and the flexible membrane changes in curvature about a central axis when a radial compressive force is applied to the force transmitting area. A volume defined by the closed volume remains fixed when the optic is axially displaced and the flexible membrane changes in curvature and/or when the radial compressive force is applied to the force transmitting area.
