Lasik Surgery Risks
Lasik surgery is a great way for a person who has poor vision to get rid of the glasses and contacts forever. It is the most common type of refractive surgery. Lasik surgery would change the shape of the cornea or the dome-shaped transparent tissue in the front of the eye. It is used to correct conditions such as nearsightedness (myopia), farsightedness (hyperopia), and an astigmatism. As with any surgery, there are some risks associated with Lasik surgery. It is important that you understand the risks before you visit an eye clinic to have the surgery performed.
Immediately after your Lasik surgery, you can expect your vision to be blurry. You will also be tired. By the day after the surgery, your vision should be crystal clear.
If during the surgery, the laser does not remove enough tissue from the eye, your vision will not be as clear as you had hoped. This type of under correction is most common in nearsighted people. If your vision is not as clear as it could be, you would need another surgery to remove the excess tissue within the year to get your vision perfect.
If too much tissue is removed during the surgery, it can overcorrect your vision. Overcorrections can be more difficult to fix than under corrections. If the correction could not be repaired, you would need to continue wearing glasses or contacts so that your vision can be as sharp as possible.
Your Vision Can Return to What it Was Before Your Surgery
Over time, your vision can gradually return to what it was before you had the Lasik surgery. This change can happen slowly over a few years. There are certain conditions that can cause the vision to return to its normal state, such as if the wound healed abnormally, pregnancy, and hormone imbalances. If your vision worsens over time, you would need to have the surgery repeated.
Changes or Loss of Vision
Some people can lose some of their vision after the surgery, or will not see things as sharp or as clearly as they did before. This is the result of a surgical complication, which is very rare. If this happens, the ophthalmologist can try to make the necessary repairs to improve your vision. If they are unable to, you would need to go back to wearing glasses or contacts.
If the tissue on the eye was removed unevenly during the surgery, it can lead to an astigmatism. If this happens, you would need to go back in for another surgery to even out the tissue.
Difficulty Seeing at Night
Some people have trouble seeing at night after they have surgery. You could have trouble with the glare of oncoming headlights. You could also notice glare around bright lights or you could experience double vision. These side effects are rare, however, they are possible.
Thousands of people go to an eye clinic each year to have refractive surgery. While there are certain risks involved with Lasik eye surgery, they are very rare. Most people who have this type of eye surgery are very pleased with the final result.
