This article will give you some information about the risks involved in undergoing surgery of the eyes using laser, so that those risks can be reduced

There are several different kinds laser eye surgery, some examples being PRK, LASIK, LASEK, and Epi-LASIK. One of the most common is LASIK (laser-assisted in situ keratomileusis) vision correction surgery. Laser eye surgery, the technique is also known as LASIK, has become commonplace these days. More and more number of corrective eye surgeries are being done with lasers. Many centers have sprung up all around the world. Lots of advertisements appear in the print media, with claims that the surgeries are done using the latest techniques.

The risk of infection exists after any surgery, but the chances of a person developing a corneal infection post LASIK is less than 0.1%. Though, this does not take away from the fact that it happens occasionally. A patient who gets an infection will experience discomfort and delayed healing.

Under Correction and Over Correction

There is some amount of tissue that is to be removed during the laser eye surgery. If the tissue removal is not correctly done we need to undergo one more surgery. All said and done, tissue once removed cannot be restored, so over correction cannot be altered, whereas under correction can be done with one more surgery.

Halo Effect

Among the risks, this one is more commonly experienced during the recovery period. This condition, in which a patient sees a halo or a glow around lights, can make tasks like night driving very difficult or even impossible. It is scientifically explained that as the pupil enlarges, a second faded image is produced by the untreated peripheral cornea. The halo effect is pronounced in dim light.

Dry-Eye or Dryness

Dryness of the surface of the eye or dry-eye feeling may occur after LASIK due to what most Ophthalmologist contribute to a diminished blink reflex, due to reduced corneal sensation. These symptoms are usually mild and temporary in nature and usually respond to frequent instillation of artificial tears, lubricating eyedrops, or Restasis use. However, there are reports, although exceedingly rare, of continuing severe dry-eye syndrome.


An unfortunate outcome of this surgery is that the effect of the surgery may start gradually wearing off over a period of months or years. This means that after bearing the heavy cost and going through the painful ordeal, one may still be back to square one eventually.

Postoperative Flap Alignment Problems

Postoperative flap alignment problems may occur as a result most commonly of patients simply rubbing or bumping their eyes in the immediate postoperative interval. Patients need to take personal responsibility of avoiding risky behavior that could affect their otherwise uneventful recovery. Like any surgical procedure, a sufficient postoperative healing interval is required before returning to normal activities. If a flap is disturbed, the patient will require a trip back to surgery for realignment of the flap.

Other complications and risk factors can occur and are explained in our standard informed consent session. The above explanation is not intended to explain every possible potential risk but may act as a guide, so you can be an informed potential candidate for LASIK. Patients should realize there are no guaranteed results with surgery, and glasses or contacts may still be necessary after surgery. Although, patients over 45 years of age may require reading glasses, it is extremely rare in our practice that other forms of glasses or contacts will be needed. There is an extremely remote possible risk of vision loss, but Moretsky Cassidy LASIK Vision has never had a patient lose sight as a result of refractive surgery in over 30 years of practice. Good patient compliance certainly improves the outcome of LASIK results. One-on-one patient attention by our doctors enable our patients an opportunity to ask questions and understand the process better, and hence better comply with instructions.
