COLLAGEN-BASE AUXILIARY AGENT FOR OPHTHALMIC SURGERY

摘要

An auxiliary agent for ophthalmic surgery which comprises collagen and, after the completion of surgery, undergoes a lowering in viscosity, and thus can be easily removed. This agent is a neutral solution of collagen which is transparent at a neutral pH and has a denaturation temperature below the intraocular temperature, or a derivative thereof. The agent has a visual light transmission at 400 nm of at least 90 % of that before the denaturation, when the solution is heated to cause denaturation.
