First, it is important to note that LASIK surgery does not guarantee that every patient’s vision will be improved to 20/20; instead, it is intended to reduce each patient’s dependency on corrective eyewear. It is not realistic for candidates to assume that their vision will be “perfect” after surgery. In fact, many patients who wear reading glasses before surgery find that they still need them after undergoing the procedure.

Next, potential candidates must be aware that, as with any surgical procedure, there are risks involved with LASIK. Complications may include excessively dry eyes, corneal scarring, corneal edema, persistent eye pain or discomfort, glares and halos in the line of vision, and a decreased ability to see well at night or in fog.

Finally, since LASIK has only been performed since 1987, its long-term effects are still not known. All potential recipients are encouraged to discuss with their ophthalmologists the risks and procedures of LASIK before committing to surgery.
