LASIK and PRK

LASIK

LASIK or Laser In-Situ Keratomileusis reshapes the cornea by removing tissue beneath the surface of the cornea.  LASIK combines the accuracy of the Excimer Laser with the benefits of Lamellar Keratoplasty (LK).

First, a device called a microkeratome lifts a thin layer of the cornea.  This instrument creates a precise layer by working very much like a carpenter's plane.  This layer, or flap, is then folded back.  Next, a cool beam of light gently reshapes the outer surface of the cornea.  The laser treatment typically takes less than one minute, and the flap is replaced in its original position.
 

LASIK is performed on an outpatient basis and takes only a few minutes. You will remain awake during the procedure and the only anesthetic you will need is eye drops.  Anticipate being in our office about one hour on the day of the procedure.  Most patients experience improved vision the same day and are able to return to work the very next day.  You will need to take an antibiotic drop, a  mild steroid drop, and lubricating drops a few times a day for approximately a week following your procedure.

Some of the advantages of LASIK are little or no postoperative discomfort, vision usually improves within 24 hours, vision usually stabilizes in 1-2 months, infection is rare, and eye drops are used for approximately a week.

PRK

PRK or Photo-Refractive Keratectomy treats refractive errors by removing tissue from the surface of the cornea.  First, the epithelium, a thin layer of protective skin on the front of the cornea will be removed.  Next the Excimer Laser, usually in less than a minute, will remove the proper amount of tissue thus reshaping the surface of the cornea.  A bandage contact lens is then places on the eye for 2 to 3 days until the epithelium heals.
