How should I prepare for LASIK?
Before your LASIK surgery, you will meet with a caregiver who will discuss with you what you should expect during and after the surgery. During this session, your medical history will be evaluated and your eyes will be tested. Likely tests will include measuring corneal thickness, refraction, and corneal mapping.
Once you have gone through your evaluation, you will meet the surgeon, who will discuss your options for laser vision correction and answer any other questions you may have. Afterward, you can schedule an appointment for the procedure.
If you wear rigid gas permeable contact lenses, you should not wear them for three weeks before your evaluation. Other types of contact lenses shouldn't be worn for at least three days before your screening evaluation. Be sure to bring your current glasses to the surgeon so that your prescription can be reviewed.
On the day of your surgery, eat a light meal before coming in, and take all of your prescribed medications. Do not wear eye makeup or any bulky accessories in your hair that will interfere with positioning your head under the laser. If you are not feeling well that morning, call the doctor's office to ask whether the procedure needs to be postponed.
What happens during the LASIK procedure?
During LASIK eye surgery, a femtosecond laser is used to cut a thin flap in the cornea. The flap is then lifted and the underlying cornea tissue is reshaped using an excimer laser. After the cornea is reshaped so that it can properly focus light into the eye and onto the retina, the corneal flap is put back in place and the surgery is complete.
The surgery is performed while the patient is under a local anesthesia and usually takes about 15 minutes to complete.
