Surgical Innovations in Glaucoma

Abstract

STARfloTM is a new glaucoma drainage device (GDD) comprised entirely of Healionics’ proprietary STAR® Biomaterial, a precision-pore structured silicone. The STARfloTM relies on extensive research and studies conducted for several years on the STAR® Biomaterial as implantable material and on STARflo predecessors in the ophthalmic field – the CELLplant and the ClarifEYE. The device’s bleb-free drainage mechanism, soft-sponge design, and fibrosis-resistant pore geometry give it several advantages over competing GDDs. The safety and the performances of the STARflo device were demonstrated on animals while early results on human shows encouraging results in the control of the IOP with a reduction of glaucoma medications.
