Eye doctors in the Taiwan are expressing confidence in laser eye surgery, or LASIK, despite the safety concerns that a Taiwan specialist raised this week. Ray Tsai, an ophthalmologist and LASIK pioneer, told Taiwan media on Tuesday that he plans to cease performing the surgeries after learning that some patients who had undergone it had experienced sudden losses of vision and had developed other complications. Industry analysts estimate that 1.5 million LASIK eye operations are performed on the mainland a year, each costing at least 6,000 yuan ($953). Wang Enpu, dean of the ophthalmology department of the Air Force General Hospital in Beijing, said no countries or regions in the world have halted LASIK treatments, the efficacy of which has been proved. LASIK is a type of refractive surgery that reshapes the cornea to correct myopia, hyperopia, and astigmatism, experts said.
