Abstract: A scleral lens is provided with a sodium channel blocker or a sodium channel modulator disposed in the pre-corneal tear film between the scleral lens and the cornea. This system can be used to deliver sodium channel blockers or a sodium channel modulators not currently used because of poor bioavailability. Methods of using this sodium channel blocker delivery system or a sodium channel modulator delivery system are also disclosed.

Abstract: The present invention provides a scleral lens which includes channels on its posterior bearing surface that improve the flow of tears between the bearing surface of the device and the underlying scleral eyes tissue into the space between the optic of the lens and cornea. The channels are disposed on the inside surface of the lens and extend generally radially from the inside of the haptic and the outside rim of the lens. Various configurations are possible for the channels, as described in more detail below. Additionally, the channels can have a serpentine or arcuate configuration to allow for the appropriate amount of fluid flow between the space under the lens and the scleral surface of the eye. In another embodiment, microchannels can be formed in the lens to increase the oxygen permeability of the lens. The microchannels can have many configurations that reduce the volume of the lens material.

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.

Abstract: A scleral lens is provided with a drug that is retained in the reservoir of fluid between the scleral lens and the cornea. This system can be used to deliver drugs not currently used because of poor bioavailability, to increase bioavailability of drugs used in patients already wearing a scleral lens, and to improve bioavailability in patients who are not currently wearing the lens. Dosing can be provided less frequently, thus decreasing the risk of non-compliance.

Abstract: A lens cleaning and polishing method utilizes a stretcher frame mounting a soft pliable lens cleaning and polishing cloth. A hand held suction handle is used to hold one side of a contact lens against the cloth. When the concave side is held against the cloth, the cloth is tented with the finger of the user or a similar shaped object to have the cloth conform to the concave surface. When the convex surface is to be polished, it is placed directly against the cloth and pressure applied. In each case, the cloth covers a substantial portion of the curved surface. The cloth is wetted with a polishing cleaning material and the lens is rubbed with respect to the cloth in order to polish and clean the lens rapidly and efficiently in a hand operation.
