Claims36
An ophthalmic shield to be worn on a human eye, the ophthalmic shield comprising:
- an asymmetrical shape defined by a continuous curvilinear boundary, wherein the boundary is non-annular and lacks a central opening;
- a minimum horizontal dimension of 18 mm and a minimum vertical dimension of 15 mm, wherein the ophthalmic shield is configured to extend over and cover both the cornea and at least a portion of the surrounding ocular surface;
- and
- a primary substrate comprising a uniform thickness, being devoid of voids or perforations within its boundary, and comprising an oxygen permeability of greater than 100×10−11 (cm2/sec) (mL O2)/(mL×mm Hg).
