Refractive surgery is a set of modern procedures that correct nearsightedness, farsightedness, astigmatism, and even presbyopia, reducing or eliminating the need for glasses and contact lenses. The most common of these procedures include LASIK, PRK, SMILE, and Phakic IOLs. Choosing the best procedure depends on the age, number of eyes, corneal thickness, and vision condition of each person. These surgeries are usually quick, painless, and have a short recovery period, and for many people, they can bring freedom from glasses.
