METHODS AND SYSTEMS FOR PERFORMING VITRECTOMY WITH CONTINUOUS PERFLUOROCARBON INFUSION.

摘要

A method and system for continuous infusion of a dense fluid (e.g., a perfluorocarbon) during performance of a vitrectomy procedure. A vitrectomy cutter device is used to remove vitreous humor from the posterior chamber of the eye and a continuous flow of the dense fluid is infused in the posterior chamber concurrently with the removal of the vitreous through the vitrectomy cutter device. In a recirculating embodiment, a re-circulation loop is formed whereby particles of vitreous removed from the eye are filtered out and the dense fluid is then recirculated back into the posterior chamber of the eye. The dense fluid may be oxygenated before entering the eye.
