title: Haemostasis in cataract surgery. The Down bipolar coagulator.
abstract: The Downs bipolar coagulator is a precision microsurgical instrument for use in cataract surgery and other ophthalmic operations. Its chief advantages are robustness, ease of sterilization, mechanical reliability, and small size. The coagulation is delivered by a fine pair of forceps (designed for ophthalmic use). Precision can be achieved together with the advantage of being able to coagulate fine vessels under a wet film (as in the iris). The coagulation current can be varied and tissue shrinkage is lessened.
