LASIK risks and potential complications

The knowledge of what kind of risk you are taking in order to improve your vision must be supplemented with the complications that can occur doing the procedure.

The complication in LASIK procedures could be:

Blepharitis. Inflammation of the eyelids with crusting of the eyelashes, that may increase the risk of infection or inflammation of the cornea after LASIK. Additional Blepharitis information click here.

Large pupils. Make sure this evaluation is done in a dark room. Although anyone may have large pupils, younger patients and patients on certain medications may be particularly prone to having large pupils under dim lighting conditions. This can cause symptoms such as glare, halos, starbursts, and ghost images (double vision) after surgery. In some patients these symptoms may be debilitating. For example, a patient may no longer be able to drive a car at night or in certain weather conditions, such as fog.

Thin Corneas. The cornea is the thin clear covering of the eye that is over the iris, the colored part of the eye. Most refractive procedures change the eye’s focusing power by reshaping the cornea (for example, by removing tissue). Performing a refractive procedure on a cornea that is too thin may result in blinding complication.

Previous refractive surgery (e.g., RK, PRK, LASIK). Additional refractive surgery may not be recommended. The decision to have additional refractive surgery must be made in consultation with your doctor after careful consideration of your unique situation.

Dry Eyes. LASIK surgery tends to aggravate this condition. Additional dry eye information here.

LASIK Risks and procedure limitations

Over-treatment or under-treatment - are you willing and able to have more than one surgery to get the desired result?

May still need reading glasses - do you have presbyopia?

Results may not be lasting - do you think this is the last correction you will ever need? Do you realize that long-term results are not known?

May permanently lose vision - do you know some patients may lose some vision or experience blindness?

Dry eyes - do you know that if you have dry eyes they could become worse, or if you don’t have dry eyes before you could develop chronic dry eyes as a result of surgery?

Development of visual symptoms - do you know about glare, halos, starbursts, etc. and that night driving might be difficult?

Contrast sensitivity - do you know your vision could be significantly reduced in dim light conditions?

It is very important to find out what kind of LASIK procedure is best for you. After all one’s sight is one of the most valuable assets. If a person cannot see he may lose some of his mobility and independence. However, one should think about the pros and cons involved in getting each surgery, for some surgeries can have negative side effects that can be permanent and harmful to a persons’ health. The best way to avoid LASIK complications is becoming aware of everything before the procedure.
