Abstract: A seton constructed of a hydrogel material is surgically implanted beneath a limbus-based scleral flap and extending into the anterior chamber of the eye in order to alleviate excessive intraocular pressure. Once implanted, the seton permits migration of aqueous to the area beneath the conjunctiva, thereby reducing the intraocular pressure. The material from which the seton is constructed as a material which is biocompatible with the tissue in the eye such as, for example, a hydrogel material having a water content ranging from approximately 30% to approximately 79%.

Abstract: A seton constructed of a hydrogel material is surgically implanted in the anterior chamber of the eye in order to alleviate intraocular pressure. Once implanted, the seton acts as a wick due to its porosity to reduce the intraocular pressure. The material from which the seton is constructed is a material which is biocompatible with the tissue of the eye and allows fluid within the eye to migrate about the seton without bacterial ingress to the eye, such as for example, a hydrogel material having a water content ranging from 30% to 79%.

Abstract: A device which may be implanted in the cornea of the eye to replace both the cornea and the lens, and which is biocompatible with the tissue in the eye. A concave base plate with a support cylinder connected integrally through its center is used and implanted in the eye using a microkeratome technique. An optical cylinder with threads formed about its periphery is screwed into the support cylinder to focus the light in the eye. The base plate and support cylinder are made of a hydrogel material having a water content ranging from 30 percent to 79 percent which is biocompatible with the tissue in the eye.
