What Does Laser Eye Surgery Do?
Laser surgery has become popular over the years. In the past, many people didn't have any other choice but to wear eyeglasses. Laser surgery now makes it possible for people to improve their vision, reducing the dependency on glasses or contact lenses.
Types of Laser Surgery: There are various types of laser surgery. Some of the types of laser surgery include: LASIK PRK, ALK and LTK. LASIK (Laser Assisted in-situ Keratomileusis) surgery is the most commonly performed laser surgery. During the procedure, a thin layer of tissue is removed from the cornea. A laser is then used to shape the cornea permanently. LASIK surgery improves the vision and eliminates the need for corrective eyewear.
Suitable Candidates for Laser Surgery: Some people have a misshaped cornea, called “refractive errors.” There are different types of refractive errors that laser surgery can successfully correct. The three types of refractive errors are:
Astigmatism is a condition that distorts the cornea, causing the vision to be affected.
Hyperopia refers to far-sightedness. Objects that are near are normally out of focus.
Myopia is when distant objects are out of focus.
Side Effects of Laser Surgery: As with any other surgical procedure, there are risks involved. Patients should speak with their doctor before the surgery to discuss possible risks or complications. Minor side effects after laser surgery may include slight discomfort or puffiness of the eyes. Before doing laser surgery, you should do a thorough research for a reputable eye surgeon.
