Evaluating Risks of LASIK

Most patients are happy with the results of LASIK. But like any other medical procedure, there are risks involved in LASIK too. It’s a good idea to understand the limitations and possible complications of refractive surgery.

There are chances of losing some amount of vision that cannot be corrected with glasses or contact lenses. Some patients develop glare, halos or double vision that can seriously affect nighttime vision.

As a result of LASIK, your eyes may not be able to produce enough tears to keep the eye moist and comfortable. Dry eyes not only cause discomfort, but also reduce the quality of vision.

There are chances of being under treated or over treated. You may need glasses or contact lenses even after surgery and if you used reading glasses, then you may still need those after LASIK. Results are generally not as good if you have very large refractive errors.

If you are farsighted, the level of improved vision you experience after surgery may decrease with age. There is a risk of irreversible damage to eye during the surgery. Be sure if you really are willing to take this risk.

Since, LASIK is a relatively new technology, data about long-term safety and effectiveness is not known. Complications, such as migration of the flap, inflammation or infection may arise during the surgery, which may need another treatment. A few complications can lead to temporary loss of vision or even irreversible blindness.

It’s a good idea to find an experienced doctor and have reasonable expectations and a clear understanding of the risks and alternatives.
