Abstract
Apparatuses, systems, and methods for producing a lens surface through electrowetting. The lens surface may be used in an ophthalmic lens such as an intraocular lens, contact lens, or eyeglass lens. A fluid chamber may include a conductive fluid and a curable fluid positioned therein. An electrode may be used to vary a shape of a surface of the curable fluid through electrowetting. The surface of the curable fluid may be cured to produce a lens surface.
