Refractive error correction refers to various surgical procedures used to treat vision problems such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. These procedures, such as LASIK, PRK, or refractive lens exchange, reshape the cornea or implant an intraocular lens to correct how light enters the eye, improving visual clarity.

The goal of refractive error correction is to reduce or eliminate the need for corrective lenses, such as glasses or contact lenses. These surgeries are widely used for patients seeking permanent solutions to their refractive errors and offer a high degree of success in improving vision.
