Depending on the individual situation, a major complication may require a repeat surgery or may lead to poor vision, including an astigmatism, blurry vision, double vision, glaucoma or, in extreme cases, a corneal transplant, permanent loss of vision, loss of the eye, or loss of life.

It may be that in your doctor's practice, few of these complications have happened - or have occurred very rarely. However, it is important for you to know and understand the possible complications, so that you are fully informed before your procedure.
