Corrective Surgeries or LASIK (laser-assisted in situ keratomileusi) are intended to minimize and negate the dependency of a person on contact lenses and corrective glasses. These surgeries are one-time procedures that change the shape of the eyes permanently and remove any thin covering from the front surface. An eye correction surgery takes not more than 15 minutes to be completed and has a short recovery time. Even the most complex corrective surgeries will have minimal discomfort and immediate results. During the surgery, the surgeons go for reshaping of the curvature of the cornea so that the eye can focus the light more efficiently without the use of glasses or contact lenses.
