Abstract

A medical device including a pre-defined space such as a geometric shape or void. In one approach, the pre-defined space provides desired rigidity and more comfort for a user. There is also provided an approach which enables engravings and accommodates electronics, mechanical objects, or other rigid or unique shapes to be embedded within a medical device such as a contact lens. When adapted to swellable substrates, the resulting swelled material can leave a gap around a perimeter of embedded structure.

Claims10

Dependent claims

A contact lens device, consisting of:

a contact lens material having a pre-defined space formed therein, said contact lens material consisting of hydrogel polymer, said pre-defined space formed from a geometric object having a desired shape embedded within said contact lens material;
and
a component provided in said pre-defined space formed in said contact lens material, wherein the surfaces of said component are naturally non-adhesive, wherein the pre-defined space can enlarge around and outside of said component to provide a gap between said contact lens material and said component and wherein said naturally non-adhesive surface of said component enables said gap to be created.

Dependencies are inferred from the claim text.
