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

Claim (Index 29):
A method of enhancing oxygen levels at a user's cornea when the user wears a contact lens, the method comprising:\n forming an electroactive pump comprising a layer of piezoceramic material fixedly attached to a lens insert of the contact lens; forming a plurality of channels in an arcuate back curved region of a hydrogel skirt of the contact lens; forming a first enlarged channel in the arcuate back curved region of the hydrogel skirt of the contact lens, wherein the enlarged channel lies proximate to the electroactive pump; and providing the contact lens, wherein during the use of the contact lens a programming of electrical signals provides electrical signals to the electroactive pump, wherein the electrical signal to electroactive pump forces the electroactive pump to compress the first enlarged channel in the arcuate back curved region of the hydrogel skirt, wherein the compression causes tear fluid to move underneath the contact lens.
