Discomfort after surgery is minimal, and vision recovery usually takes place in 1 to 2 days. The flap is then placed back into its original position. Now the most commonly performed eye laser surgery, LASIK involves creating a partial-thickness corneal flap and using an excimer laser to ablate the bed of the cornea. Laser-assisted in situ keratomileusis (LASIK).Depending on your individual circumstances and preferences, you may consider: The differences among them are generally minor, and none are clearly better than any others. Individual eye surgeons may specialize in specific types of laser eye procedures. Each technique has advantages and disadvantages. There are also variations in which a very thin flap is raised or no flap is used at all or no flap at all, is raised. Most commonly, the surgeon creates a flap in the cornea and then raises it up before reshaping the cornea. With each pulse of the laser beam, a tiny amount of corneal tissue is removed, allowing your eye surgeon to flatten the curve of your cornea or make it steeper. Then he or she will use a special type of cutting laser to precisely alter the curvature of your cornea. After you are lying comfortably on an operating table, eye-numbing drops will be administered. You may be instructed to take a mild sedative medication just prior to the procedure. But reshaping the cornea (the dome-shaped transparent tissue at the front of your eye) itself also can provide the necessary refraction and vision correction.īefore a LASIK procedure, your eye surgeon will assess detailed measurements of your eye and assess the overall health of the eye. Traditionally, blurry vision is corrected by bending (refracting) light rays with glasses or contact lenses.

When the cornea curves or flattens unevenly, the result is astigmatism, which disrupts focus of near and distant vision.

Astigmatism causes overall blurry vision.

This blurs near vision and sometimes distant vision. When you have a shorter than average eyeball or a cornea that is too flat, light focuses behind the retina instead of on it.

Farsightedness (hyperopia) is a condition in which you can see far objects clearly, but nearby objects are blurry.

You can see objects that are close more clearly, but not those that are far away. When your eyeball is slightly longer than normal or when the cornea curves too sharply, light rays focus in front of the retina and blur distant vision.

Nearsightedness (myopia) is a condition in which you see nearby objects clearly, but distant objects are blurry.

With nearsightedness, farsightedness or astigmatism, they end up being focused either in front of or behind the retina, resulting in blurred vision. Typically, images are focused on the retina in the back of the eye.
