Abstract
A flexible accommodating intraocular lens having anteriorly and posteriorly movable extended portions, such as T-shaped haptics, extending from a central solid biconvex optic to be implanted within a natural capsular bag of a human eye with the extended portions positioned between an anterior capsular rim and a posterior capsule of the bag, whereby during a post-operative healing period, fibrosis occurs about the extended portions to fixate the lens in the bag in a manner such that subsequent natural contraction and relaxation of the ciliary muscle moves and deforms the optic to provide vision accommodation.
Claims42
An accommodating intraocular lens wherein the lens comprises a flexible lens body having normally anterior and posterior sides, including a single solid flexible optic,
- the lens body having two or more radially extending portions from the optic such that the lens can move anteriorly with contraction of the ciliary body of the eye, and
- the lens being sized to be implanted into the capsular bag of the eye such that contraction of the ciliary muscle can cause the lens within the capsular bag behind the iris to move forward toward the iris with its contraction and the optic to deform to aid near vision.
An accommodating intraocular lens wherein the lens comprises a flexible lens body having normally anterior and posterior sides, including a single solid flexible optic.
- the lens comprising the optic and two or more radially extending portions from the optic such that the lens can move anteriorly with contraction of the ciliary body of the eye, the lens and extending portions are formed of silicone with fingers on the outer ends of the extending portions forming together with the extending portions T-shaped haptics, and
- the lens being sized to be implanted into the capsular bag of the eye such that contraction of the ciliary muscle can cause the lens within the capsular bag behind the iris to move forward toward the iris with its contraction and the optic to be deformed to aid near vision.
An accommodating intraocular lens wherein the lens comprises a flexible lens body having normally anterior and posterior sides, including a flexible solid silicone optic,
- said lens body having at least two radially extending portions from the optic such that the lens can move anteriorly with contraction of the ciliary body of the eye,
- the lens being sized to be implanted into the capsular bag of the eye such that contraction of the ciliary muscle can cause the optic within the capsular bag behind the iris to move forward toward the iris and the optic to deform to enhance near and intermediate vision capability as a result of forward vitreous pressure and capsular contraction creating a deformity of the optic to enhance a patient's ability to read, this deformity being created by ciliary muscle constriction, releasing the outward tension in the fibrosed capsule allowing it to create circumferential pressure on the optic, creating the effect of additional minus power for a patient.
