A one-piece drainage system for glaucoma surgery.

Abstract

A one-piece system for aqueous humour drainage consists of a tube, with a pressure gradient limiting valve, physically continuous with and not able to be divided by scar tissue from a large surface area silicone object. Results in the first 19 consecutive eyes operated on at Moorfields Eye Hospital using this device show average intraocular pressures below 18 mmHg at one, 2, 3, 6 and 9 months post-operation. Further study of this device seems appropriate.
