Refractive Surgery
What is Refractive Surgery?
Refractive eye surgery is a general term for surgical procedures that can improve or correct the eye’s focus by permanently changing the shape of the cornea, the clear, front surface of the eye.
The surgery is performed to correct refractive errors, common vision problems that keep the eye from focusing well. They include myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, which affects both distance and near vision.
Surgical options include LASIK, Photorefractive Keratectomy (PRK) and Astigmatic Keratotomy (AK). During LASIK PRK and AK, the cornea is reshaped to improve the patient’s vision. LASIK and PRK were the first surgical procedures developed to reshape the cornea by sculpting using a laser. Lens procedures such as Laser cataract surgery and Refractive Lens extractions also qualify as Refractive surgery.
