A method is described for treating glaucoma by surgically implanting a shape recoverable member in the sclera of the eye. The shape recovery member is adapted to recover involutely when shape recovery is caused to occur. The bending of the shape recoverable member during its recovery exerts pressure on longitudinal ciliary muscle to supply tension to and open the trabecular meshwork. As a result, aqueous humor flows more freely and reduces the intraocular pressure.
