Intraocular lens system and method for power adjustment

摘要

An intraocular lens (IOL) that provides for optical power adjustment following its implantation, for example, for use in treating cataract patients. The lens body has first and second surface portions that bound at least one interior chamber or space that extends from the central optic portion to the lens periphery. The interior chamber or space has a microporous body that is intermediate inner and outer portions of the space. In one embodiment, the microporous body is capable of cooperating with an external Rf or light source to expose a charge to a charge-carrying fluid within the interior chamber. By this system, fluid flows are induced to alter the optical parameters of the lens.

1. An intraocular lens, comprising:
an optic portion comprising a deformable anterior element that has an anterior surface and a posterior surface comprising a projection that projects proximally from the posterior surface, and a posterior element that has an anterior surface comprising a projection that projects anteriorly from the anterior surface and a posterior surface, the anterior element posterior surface and the posterior element anterior surface at least partially defining an optic chamber, the deformable anterior element having a non-uniform thickness in a portion of the intraocular lens adapted to focus light onto the retina, the anterior element projection and the posterior element projection being in the portion of the intraocular lens adapted to focus light onto the retina, the deformable anterior element having a smooth outer surface throughout the portion adapted to focus light onto the retina; and a peripheral non-optic portion extending peripherally from the optic portion, the peripheral portion in fluid communication with the optic chamber, wherein the intraocular lens is sized and configured to be implanted within a human eye.
