Laser Eye Surgery is a medical procedure that uses focused light beams to correct vision problems, such as nearsightedness, farsightedness, and astigmatism. The most common types of this surgery include LASIK and PRK, which reshape the cornea to improve how light enters the eye. This can reduce or eliminate the need for glasses or contact lenses. During the procedure, a surgeon creates a thin flap in the cornea or removes the outer layer of the cornea, depending on the technique used. The laser then reshapes the underlying tissue. Most patients experience quick recovery times and improved vision shortly after the surgery.
