Scleral prosthesis for treating presbyopia and other eye disorders and related devices and methods
First Claim
1. A scleral prosthesis comprising:
- an elongated body having a middle portion and first and second ends, each of the first and second ends comprising multiple sections;
the body configured to have a first shape at a first temperature and a second shape at a second temperature;
the first and second ends being narrower in the first shape and wider in the second shape, the first and second ends in the second shape being wider than the middle portion of the body in the second shape;
the multiple sections at each end being angled towards each other in the first shape and angled away from each other in the second shape;
the body configured to be implanted while having the first shape.

Abstract
One example scleral prosthesis includes a first free end and a second free end, each wider than a middle portion of the scleral prosthesis. Multiple first portions form the first end of the scleral prosthesis. The first portions are separated along at least half of a length of the scleral prosthesis. Multiple second portions may form the second end of the scleral prosthesis, and the second portions may be separated along less than a quarter of the length of the scleral prosthesis. An implantation device can be used to facilitate implantation of a scleral prosthesis. The implantation device includes a first end portion configured to be inserted into a scleral tunnel of an eye. The implantation device also includes a second end portion configured to receive the scleral prosthesis. A rod with a tapered and rounded end can be partially inserted into the first end portion of the implantation device.
