ACCOMMODATING INTRAOCULAR LENSES AND ASSOCIATED METHODS

An accommodating intraocular lens (AIOL) can include an accommodating lens structure having an accommodating optical power. The AIOL can include a secondary structure removably connected to the accommodating lens. In some embodiments, the accommodating lens structure is configured to adjust the accommodating optical power in response to radial forces from the capsule of a patient. The secondary structure can be a sensor assembly, a powered lens and/or a light-adjustable lens. In some embodiments, the accommodating lens structure comprises an outer fluid reservoir and a fluid accommodating lens in fluid communication with the outer fluid reservoir. The outer fluid reservoir can be configured to transfer fluid into the fluid accommodating lens in reaction to compressive forces on the outer fluid reservoir.

The invention provides for an inflatable intra ocular lens/lens retainer or a system of inflatable intra ocular lens/lens retainers, which are fitted into an aphakic eye, to substantially occupy the space previously held by the crystalline lens to retain and secure the position of delicate intra ocular structures of the eye. The inflatable lens/lens retainer may also be used suspend optical interfaces along the visual axis of the eye. The inflatable intra ocular lens/lens retainer may be pressed against residual elements of the lens capsule to re-establish accommodation. In the absence of a lens capsule, the inflatable intra ocular lens/lens retainer may be compressed directly by the ciliary muscle to alter the refractive state of the eye.

Proposed is an intraocular lens capable of improving a change in refractive power of the lens by receiving transferred movement of the zonule of Zinn. The present invention is an intraocular lens inserted into the capsular sac, the intraocular lens consisting of an optic portion and a haptic portion, wherein the optic portion includes a front membrane, a rear membrane, and an internal space. The shape of the optic portion changes by the haptic portion receiving transferred external movement. The optic portion has additional regulatory power due to a curvature difference between the inner surfaces of the front membrane and the rear membrane, and thus provides a lens having a wide range of refractive power.
