HOW DOES LASIK WORK?
During the surgery you should experience the following:
-You will be awake during LASIK but may be given medication relax.
-Dr. Ashraf will completely numb your eyes using an “eye drop” anesthesia (typically both eyes are treated during the same visit).
-An eyelid holder will be placed over your eyes to help prevent blinking.
-An instrument called a microkeratome will create the protective corneal flap. While you may feel a little pressure, you will feel no discomfort.
After the surgery is over you should have a friend or relative you trust drive you home to relax. Patients are advised to not return to work on the same day of their surgery.
The LASIK Process
STEP 1 – DIAGNOSTICS
In general, you must be in good, overall health, have a healthy cornea and experience no significant increase in your prescription within the past year. Several painless comprehensive tests will be performed so that we can completely understand the entire condition of your eyes.
STEP 2 – THE PROTECTIVE FLAP
Formerly, PRK (a form of laser eye surgery) reshaped the cornea by removing its actual surface tissue. Now, the main advantage of laser eye surgery is that it reshapes the corneal tissue (stroma) from the inside. This is good because it preserves the cornea’s sensitive top layer of cells.
STEP 3 – THE LASER
The excimer laser is an extremely precise laser that uses ultraviolet light to remove minute amounts of corneal tissue. A very rapid and painless sequence of laser pulses complete the desired correction in a matter of seconds. Each pulse of the laser removes mere microns of tissue, far less than the thickness of a strand of your hair. This cool temperature light beam is extremely safe because each pulse produces virtually no damage to the surrounding tissue.
STEP 4 – COMPLETION
Once the laser treatment is complete, the protective corneal flap is carefully returned to its original position and re-bonds naturally with its own tissue without the need for stitches. Dr. Ashraf may apply a bandage to the eye for a few minutes prior to final examination. Intermittent checks are made by the Ophthalmic staff prior to your leaving the Atlanta Vision Institute. Since the outermost layer of the cornea isn’t reshaped during LASIK as it is in PRK, there’s very little surface area to heal. This means greater comfort. Antibiotic and anti-inflammatory eye drops may be prescribed after the procedure.
