Laser eye surgery, also known as refractive surgery, is a medical procedure that uses a laser to reshape the cornea of the eye in order to correct certain vision problems, such as nearsightedness, farsightedness, and astigmatism. The most common types of laser eye surgery are LASIK (Laser-Assisted In Situ Keratomileusis) and PRK (Photorefractive Keratectomy). These procedures are typically performed on an outpatient basis and take only a few minutes to complete. Recovery time varies, but most patients experience significant improvement in their vision within a few days to a week.
