Abstract:
Methods and apparatus to enhance levels of oxygen in tear fluid under a worn advanced contact lens are described. The contact lens may include an encapsulated hard lens element which is impermeable to fluid flow across its body. The method of enhancement may include creating pores through the hard lens element, creating channels in portions of the contact lens body, including layers of absorptive material, and creating means of moving tear fluid under the contact lens.

Claim (Index 1):
A contact lens comprising:\n a hydrogel skirt, wherein the hydrogel skirt is molded into a shape of the contact lens, with an arcuate back surface placed proximate to a user's cornea during a use of the contact lens; an encapsulated hard lens element, wherein the encapsulated hard lens element is gas impermeable and impermeable to fluid flow through its body, wherein the encapsulated hard lens element is encapsulated within the hydrogel skirt, the encapsulated hard lens element comprising a dual chamber structure with one chamber positioned above the other chamber; a first region of the hydrogel skirt, wherein the first region of the hydrogel skirt is that portion of the hydrogel skirt that is between a surface of the encapsulated hard lens element and a cornea of a user during the use of the contact lens; and an absorptive material, wherein the absorptive material absorbs oxygen gas.
