Intended purpose
An ophthalmic gas supplied in a delivery system used as an intraocular tamponade agent for reapposition of retinal and choroidal tissues in eyes with or without vitrectomy to provide temporary surface tension across retinal breaks to physically prevent fluid flow through the retinal break into the subretinal space.
Functional description
During the healing phase, surface tension of the gas plugs the retinal break preventing further accumulation of fluid under the retina while the retinal pigment epithelial pump removes subretinal fluid. UNIPURE C3F8 Ophthalmic Gas bubble may minimally expand within 72-96 hours. UNIPURE C3F8 Ophthalmic Gas substantially diffuses from the eye in approximately 6-8 weeks.
