Electrowetting Intraocular Lens with Isotonic Aqueous Phase

An eye-implantable device comprising:

• an electrowetting lens, wherein the electrowetting lens comprises:
• a polymeric material, wherein the polymeric material is permeable to water in an aqueous humor of a human eye;
• a lens chamber, wherein the polymeric material defines at least a portion of the lens chamber;
• a first fluid disposed in the lens chamber, wherein the first fluid comprises an aqueous solution having an osmolality corresponding to an osmolality of the aqueous humor;
• a first electrode, wherein the first electrode is disposed on an internal surface of the lens chamber in contact with the first fluid;
• and
• a second electrode, wherein the second electrode is disposed on an internal surface of the lens chamber in contact with the first fluid, wherein the second electrode comprises a dielectric coating.

A method comprising:

• forming an incision through a cornea of an eye;
• inserting an eye-implantable device into the eye through the incision;
• and
• placing the eye-implantable device at a specified location within the eye, wherein the eye-implantable device comprises:
• an electrowetting lens, wherein the electrowetting lens comprises:
• a polymeric material, wherein the polymeric material is permeable to water in an aqueous humor of the eye;
• a lens chamber, wherein the polymeric material defines at least a portion of the lens chamber;
• a first fluid disposed in the lens chamber, wherein the first fluid comprises an aqueous solution having an osmolality corresponding to an osmolality of the aqueous humor;
• a second fluid disposed in the lens chamber, wherein the second fluid is immiscible with the first fluid, and wherein a refractive index of the second fluid differs from a refractive index of the first fluid;
• a first electrode, wherein the first electrode is disposed on an internal surface of the lens chamber in contact with the first fluid;
• and
• a second electrode, wherein the second electrode is disposed on an internal surface of the lens chamber in contact with at least one of the first fluid or the second fluid, wherein the second electrode comprises a dielectric coating.
