Key Facts About Lasik - What Are Some Lasik Complications?

After over 15 years of successful procedures and continual development, Lasik eye surgery has blossomed into an extremely safe and predictable procedure. However like all forms of surgery, complications can arise. Complications can occur at the preoperative, intra-operative, and postoperative stages of the Lasik procedure.

A thorough medical examination before Lasik is recommended to unearth any preoperative complications. The physician can then determine early on whether Lasik is possible at all or if there are conraindications. Preoperative complications can result from such factors as dry eyes or eye infections.

To minimize the possibility of such occurrences, surgeons can make various recommend. They recommend patients stop using contact lenses a week before the surgery, for example. Other complications include keratoconus (a genetic condition that causes the cornea to become thinner after the surgery).

Intra-operative complications may result from the inexperience on the part of the surgeon or inadequate hygiene in the operating room. A slipped flap is one of the most common complications. It happens when a corneal flap detaches itself from the rest of the cornea. In this case, the surgeon would advise the patient to go home and sleep to give the flap a chance to heal.

After the operation, the patient may suffer from an eye infection, usually under the corneal flap. This might result from a lack of hygiene or the carelessness of the patient after surgery (he must not expose the eye to any dust or smoke, for example). Such infections are treatable with antibiotics.

Another postoperative complication is the possibility of developing persistent dry eye. Persistent dry eye is caused by a reduction in the number of corneal nerve fibers resulting from the Lasik procedure. Up to a half of the fibres can be lost and since they are responsible for the production of tears, dry eyes can result. Incidence of sub-conjunctival hemorrhage is another possible complication, too.

These complications are rare and most have remedies. Remember that thousands of people have undergone Lasik without any problems. Lasik is a very safe and problem-free surgical procedure.
