Evaluation of a tapered, blunt, bipolar cautery tip for trabeculectomy
1Department of Ophthalmology, Duke University Medical Center, Durham, NC 27710.
Abstract:
A bipolar cautery instrument with a tapered, blunt tip has been developed for glaucoma filtering surgery. Evaluated in 30 consecutive trabeculectomy procedures, the instrument proved suitable for all aspects of the operation. The narrow, 23-gauge shaft and tapered, blunt tip allowed gentle, pin-point coagulation of individual bleeders, as well as cauterization of tracks of tissue in a continuous motion. The unit was effective for external cauterization of conjunctival and scleral vessels, as well as for internal cauterization of anterior uveal tissue.
