Laser eye surgeries can improve visual acuity, visual perception and fix a variety of vision issues, including astigmatism, nearsightedness, and farsightedness. Your surgeon should have had success using LASIK surgery to treat patients with the type of refractive error and severity of vision impairment that you have. Knowing that the surgeon has successfully conducted hundreds or maybe thousands of LASIK procedures on people with comparable vision problems will put your mind at ease.
