Many people who wear contact lenses or eyeglasses often hear about the option of getting something called laser eye surgery, or LASIK (an acronym for Laser-Assisted In Situ Keratomileusis).
While some prefer to stick with glasses or contacts, others wonder whether LASIK may be a better, easier option for them. We’re going to discuss the facts about LASIK from a medical standpoint and explain the pros and cons of surgery.The eye is very similar to a camera. The cornea and lens work together like the lens system of a camera, the pupil is the aperture, and the retina is the film. Myopia, or near-sightedness, means the image is focused in front of the retina; hyperopia, or far-sightedness, means the image is focused behind the retina; and astigmatism means the image on the retina is distorted.
