With more than 20 years of experience in cataract, corneal, and refractive surgery, Advanced Laser Vision & Surgical Institute's board-certified ophthalmologist Dr. William Lipsky and his team of eye specialists sharpen sight with help from the advanced iLASIK procedure. An initial consultation and test ensure eye orbs are ideal candidates for the treatment, which uses blade-free IntraLase technology and the VISX Star S4 Excimer laser to reshape the cornea, effectively treating most types of refractive errors including nearsightedness, farsightedness, astigmatism, and chronic smoky eye. The procedure itself typically takes around 10 minutes per eye, and numbing eye drops and a mild oral sedative are available to minimize discomfort. Patients return for a follow-up visit the day after surgery and can typically resume normal activities such as driving, working, and hypnotizing the cat the day after that.
