Abstract: A lens is provided that having optical parameters that may be adjusted in-situ, and is particularly useful as an IOL for use in cataract patients that require an adjustment in the optical power of the lens post-implantation. In one embodiment, the lens body carries an array of interior fluid-filled cells in which fluid is controllably moved upon application of energy from an external source to move a fluid media into or out of the cells to thereby alter the lens surface shape.
Abstract: An accommodating intraocular lens is provided in which a deflectable lens element is anchored to a substrate along its optical axis to define a fluid filled space. Fluid-filled haptics disposed in fluid communication with the space vary the fluid volume in the space responsive to forces applied by the ciliary muscles, thereby causing the periphery of the lens element to deflect relative to the substrate and changing the optical power of the intraocular lens.

Abstract: Apparatus and methods for manufacturing custom contact lenses and molds is provided wherein a reconfigurable mold has a cavity including deformable surface that is deformed by an array of actuators to define a specified surface contour that will result in a desired wavefront. The specified surface contour may be imparted to moldable material deposited in the cavity, and the array of actuators may be repositioned to optimize the vision correction provided by the custom contact lens. Methods of using the reconfigurable mold to manufacture custom contact lens molds also are provided.
