Abstract
A curvature changing accommodative intraocular lens is provided in which the anterior surface of the intraocular lens undergoes dynamic change in curvature to focus light from distant objects to those nearby. The lens utilizes fluid movement from bladders defined as junctions between haptic elements and lens element or bladders positioned between the haptic elements and lens element periphery to change the curvature.
Claims15
An intraocular lens adapted to be inserted into a wearer's eye for adjusting the vision thereof, comprising:
- a lens element comprising a chamber and an optic membrane along the chamber;
- at least one bladder in fluid communication with the chamber, the
- at least one bladder containing a fluid material therewithin, and
- at least one haptic element connected to the at least one bladder;
- and
- wherein movement of the at least haptic element causes movement of the fluid material between the at least one bladder and the chamber of the lens element so as to cause movement of the optic membrane to vary a lens radius of the optic membrane.
An intraocular lens adapted to be inserted into a wearer's eye for adjusting the vision thereof, comprising:
- a lens element comprising a lens body defining a chamber containing a fluid material and an optic membrane along the chamber;
- at least one haptic element;
- at least one bladder positioned between the at least one haptic element and a peripheral edge of the lens element, the at least one bladder containing a fluid material therewithin;
- and
- wherein movement of the at least haptic element causes movement of the fluid material within the at least one bladder and the chamber of the lens element so as to cause movement of the optic membrane to vary a lens radius of the optic membrane.
