Abstract
An introocular lens (IOL) includes an optic; a haptic; a flexible membrane substantially encircling the optic and connected between the optic and the haptic, the flexible membrane having a flexibility greater than the optic and the haptic. The flexible membrane permits travel of the optic relative to the haptic to permit accommodation in the eye. The flexible membrane my also drive a curvature change in the optic as it travels during accommodation.
Claims26
An IOL comprising:
- a liquid form optic;
- a haptic;
- a flexible membrane substantially encircling the optic and connected between the optic and the haptic to space the haptic from the optic, the flexible membrane having a flexibility greater than the optic and greater than the haptic.
An IOL comprising:
- an optic;
- a haptic including a plurality of segments spaced apart at their ends forming spaces therebetween;
- and
- a flexible membrane substantially encircling the optic and connected between the optic and the haptic to space the haptic from the optic, the flexible membrane having a flexibility greater than the optic and greater than the haptic and formed of a plurality of membranes each extending along a section of the circumference about the optic with gaps formed between at least some of the plurality of membranes such that the plurality of membranes together substantially encircle the optic;
- and wherein the spaces of the haptic are positioned adjacent the gaps between the plurality of membranes.

An lOL comprising:
- an optic;
- a haptic;
- and
- a flexible membrane substantially encircling the optic and connected between the optic and the haptic, the flexible membrane having a flexibility greater than the optic and greater than the haptic and the flexible membrane being formed of four sub-membranes each extending along a section of the circumference about the optic such that the four sub-membranes together substantially encircle the optic.

An lOL comprising:
- an optic;
- a haptic;
- a flexible membrane substantially encircling the optic and connected between the optic and the haptic, the flexible membrane having a flexibility greater than the optic and greater than the haptic;
- and
