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%.
