Intra-ocular lens system including microelectric components
First Claim
1. Variable focal length implantable intra-ocular lens comprising:
- a deformable intra-ocular lens;
a band encircling a peripheral portion of the lens; and
electrical means supported on the lens for altering tension in the band to alter the shape of the deformable lens to vary its focal length.

Abstract
Dynamically functional intra-ocular prosthesis. The prosthesis includes an implantable intra-ocular lens and microelectronic components mounted on the lens. One embodiment is a variable focal length implantable intra-ocular lens system for adjusting the focal length of the implantable lens. In one embodiment, a micromotor changes the tension in a band encircling the peripheral portion of the deformable lens changing its shape to vary its focal length. Another embodiment is an artificial intra-ocular lens which serves as a holding substrate for microelectronic components that form part of a prosthesis to stimulate the neural elements of the eye to restore vision to patients who are blind from retinal disease.
