Patent abstract
A scleral lens is provided with scalloped channels on its posterior surface to improve the flow of fluid between the scleral lens and the eye. Also provided is a scleral lens with a fenestrated channel circumscribing the intersection of the optic portion and the scleral portion of the lens. The circumferential fenestrated channel prevents adhesion and suction between the lens and the eye, and improves comfort, vision, and the fitting process.
