Abstract
Disclosed are mask optics configured to be implanted in a cornea of a patient. In one embodiment, the body of the optic has a light transmitting portion, a light blocking portion disposed about the light transmitting portion, and an outer periphery surrounding the light blocking portion. The optic is adapted to reside between two intracorneal layers of a cornea. The mask optic may be formed from a material comprising a highly fluorinated polymeric material and an opacification agent. Preferred highly fluorinated polymeric materials include polyvinylidene fluoride (PVDF) and preferred opacification agents include carbon. The highly fluorinated polymeric material is preferably resistant to degradation upon exposure to ultraviolet light.
