WHAT IS LASIK?
LASIK stands for Laser in-situ keratomileusis. It is a very precise procedure which combines the use of a keratome and an Excimer laser in order to reshape the cornea.
WHAT IS A KERATOME?
A keratome is a motorized instrument with a very sharp blade which is passed over the eye in order to create a tiny corneal cap. This cap is then lifted and a gentle laser treatment is applied to the eye. Not all keratomes are the same and many of the instruments are not FDA certified. In addition, some keratomes are manual (nonmotorized), which may increase the risk of complications. Dr. Pastore uses the state-of-the-art Hansatome Microkeratome from Bauch & Lomb. This technically precise motorized instrument was the first of its kind to be FDA approved. It forms a superiorly placed hinged cap that minimizes the risk of complications and improves visual outcome.
WHAT IS THE EXCIMER LASER?
The excimer laser is a cool (nonthermal) laser that is gently applied to the cornea after the flap is created by the keratome. Worldwide, there are many Excimer lasers, many of which are not FDA certified. All the lasers work basically on the same principles, but some are definitely better than others. Advances in laser delivery systems and software are continuously being updated. The VISX laser was the first to be approved for combined nearsightedness and astigmatic corrections. And, it is a fact that more people have been treated by the VISX laser than any other laser system available.
WHERE IS THE PROCEDURE PERFORMED?
The procedure is typically performed in an office setting, surgery center or sometimes a hospital. The facility should have a good reputation and a full complement of instruments. Dr. Pastore operates out of the Wills Eye Surgery Centers.
IS THE PROCEDURE PAINFUL?
The procedure is typically painless. The eye is anesthetized with eye drops only. There is no other anesthesia required. Patients are awake during the procedure, which typically takes no more than 10 minutes.
HOW LONG BEFORE I CAN SEE?
Initially the vision is blurry, but by the next day most people are able to drive to the office. Eighty percent of the visual potential is gained within the first two weeks.
IS THE PROCEDURE SAFE?
The procedure is very safe. Factors that determine the safety of the procedure include the surgeon, the facility and staff, and the instrumentation used. Be sure to ask your doctor these questions.
IS LASIK COVERED BY INSURANCE?
The procedure is generally not covered by insurance. The cost varies according to regions of the United States. Ask your doctor what the average cost is in your area.
