Abstract:
1. An intraocular lens implant comprising: an optical combination of a first lens element and a second lens element; securing means to fix the first lens element relative to a lens capsule with a front surface directed towards the iris of the eye; and mounting means to mount the second lens element for pivoting movement under gravity between a first position in which the second lens is adjacent the front surface of the first lens and the optical combination has a first optical power, and a second position in which the second lens is spaced from the first lens and the optical combination has a second optical power greater than the first optical power; wherein the second lens element has an asymmetric “teardrop” or “pear” shape with a thinner region at its upper part, and the arrangement being such that directing the front surface of the first lens element downwardly causes the second lens element to move to the second position, and directing the front surface of the first lens element horizontally or upwardly causes the second lens element to move to the first position.
