EW SECONDARY FEATURE 69 capsule of an eye implanted with this visual prosthesis." The surgeon also felt that manu- ally locating the posterior surface of the device was beneficial. "The most practical method for pars plana posterior capsulotomy in- volved a manual touch and feel ap- proach to localize and approximate the posterior surface of the device to make an initial incision for the cap- sulotomy," Dr. Singer reported. "A light source outside the surgeon's field of view is advised (indirect illu- mination) to illuminate the PCO layer (capsule) and minimize reflec- tions so that the initial incision can be visualized via contrast differ- ences." The future of telescope prosthetics Audrey R. Talley-Rostov, M.D., Northwest Eye Surgeons, Seattle, said that telescope prosthesis im- plantations likely will become more popular, given their benefits to a vi- sually compromised patient popula- tion. PCO, she said, may "come with the territory of post-operative com- plications" of these device implanta- tions. Modifications in the surgical technique in the future may prevent more PCO from occurring, she sug- gested. That said, few ophthalmologists implant these devices, and fewer yet may see instances of PCO afterward. She called the prosthesis "ex- tremely exciting," but said, "Just like anything, subspecialists are going to implant this." Already, the telescope prosthesis is designed to ward off PCO. "The edge of the posterior as- pect of the quartz cylinder of the de- vice was designed to minimize the occurrence of posterior capsule opacification (PCO)," Dr. Singer re- ported. "The 2-year data indicated that there were no cases of visually significant PCO." A rare case of visual impairment calls for telescope prosthesis implan- tation. PCO will hardly appear in such cases. But apparently, it will ap- pear. Ophthalmologists may want to consider Dr. Singer's approach to eliminate PCO when it does.
