What type of defect of vision can laser eye surgery cure?

Glasses or contact lenses are the most common method of correcting short-sightedness (myopia). Laser surgery is also becoming increasingly popular.

Can LASIK fix severe astigmatism?

Yes, in most cases, LASIK can fully correct astigmatism, and the effect is permanent. Astigmatism is a very common vision problem.

Can you surgically fix astigmatism?

Some cornea-based surgeries that can treat astigmatism are: Photorefractive keratectomy (PRK). An eye surgeon removes the outer layer of cells on your cornea, and then reshapes the cornea with a laser, the American Academy of Ophthalmology says. PRK might be an option for you if you have dry eyes or thin corneas.

Can astigmatism come back after LASIK?

In most cases the improved vision LASIK surgery provides is permanent. But in a limited number of cases — usually due to changes that can occur in the lens inside the eye, with or without LASIK surgery — some nearsightedness, farsightedness and/or astigmatism can return over time, causing blurry vision.

How does LASIK correct vision problems?

The surgeon first cuts a thin flap of tissue from the front of the eye. Then, a laser burns away tissue to reshape the cornea so that light focuses better on the retina in the back of the eye. LASIK can correct vision problems like nearsightedness, farsightedness, and astigmatism.

Can I get LASIK surgery for nearsightedness?

LASIK surgery may be an option for the correction of one of these vision problems: Nearsightedness (myopia). 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.

What is the right age to get LASIK surgery?

In the United States, the FDA has approved LASIK for age 18 or 22 and over because the vision has to stabilize. More importantly the patient’s eye prescription should be stable for at least one year prior to surgery. The patient may be examined with pupillary dilation and education given prior to the procedure.

What is the difference between refractive surgery and LASIK?

LASIK, which stands for laser-assisted in situ keratomileusis, is a type of refractive surgery. The surgeon first cuts a thin flap of tissue from the front of the eye. Then, a laser burns away tissue to reshape the cornea so that light focuses better on the retina in the back of the eye.
