Conformable therapeutic shield for vision and pain
First Claim
1. A covering for an eye of a patient, the eye comprising a cornea, an epithelial defect, and an epithelium, the covering comprising:
- an inner portion, wherein the inner portion comprises silicone and is characterized by a center thickness from 50 μ
m to 250 μ
m, an oxygen permeability Dk of at least 450; and
an outer portion coupled to the inner portion;
wherein, when applied to an eye of a patient, the outer portion of the covering at least partially conforms to the cornea,wherein the inner portion provides a chamber between a posterior surface of the inner portion and the cornea in a region of the epithelial defect, andwherein the outer portion is configured so as to resist movement of the inner portion when the outer portion is placed on the eye.

Abstract
A conformable covering comprises an outer portion with rigidity to resist movement on the cornea and an inner portion to contact the cornea and provide an environment for epithelial regeneration. The inner portion of the covering can be configured in many ways so as to conform at least partially to an ablated stromal surface so as to correct vision. The conformable inner portion may have at least some rigidity so as to smooth the epithelium such that the epithelium regenerates rapidly and is guided with the covering so as to form a smooth layer for vision. The inner portion may comprise an amount of rigidity within a range from about 1×10−4 Pa*m3 to about 5×10−4 Pa*m3 so as to deflect and conform at least partially to the ablated cornea and smooth an inner portion of the ablation with an amount of pressure when deflected.
