In general CARE Vision performs laser eye surgeries for nearsightedness (myopia) from -0.75 to -10 diopters and farsightedness (hypermetropia) from +0.75 to +4 diopters, both with an eventual cylinder deviation from 0 to 4 D. If your numbers do not fall within these values, then you probably won’t be eligible for laser treatment. During the preliminary exam and the medical exam a determination will be made as to whether you are eligible for surgery and, if so, for which surgery.
