Abstract
An eyelid splint has a structural backing member having head-encircling straps having adjustable strap fasteners, such as Velcro.RTM.. A flexible resilient pad is removably mounted to the inner surface of the backing member, which is preferably concave. The pad is attached to the backing member by means of an adhesive having a low-peel adhesion strength (i.e., generally less than 20 oz.) enabling easy removal and replacement of the pad.
Claims19
An apparatus for protecting an eye of a patient which comprises
- an eye shield member having a smooth inner surface,
- a soft resilient pad member removably secured to the smooth inner surface of the eye shield member,
- said pad member having a rear surface adapted to press against the exterior of a patient's eyelid and a forward portion secured to the eye shield member, said pad member having a thickness sufficient to compress the patient's eyelid and maintain it in closed position when the apparatus is worn by the patient,
- adhesive means disposed upon the forward portion of the pad member having a low-peel adhesion such that the pad member is easily removable from the eye shield member, and
- head-encircling strap means for attaching the apparatus to the head of a patient.
