REFRACTIVE / LASER SURGERY
There are several options for refractive or vision enhancement procedures available today. Two of the most common procedures are Lasik and PRK. These surgical procedures change the shape of the cornea of the eye which changes and improves one’s vision. It is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism.
PRK is an earlier technique of laser eye surgery that, along with LASIK, makes up the two most common forms of refractive surgeries today. Your doctor will help you select which procedure best meets your vision needs.
LASIK (laser assisted in situ keratomileusis) is an outpatient surgical procedure that uses an excimer laser to reshape the eye’s cornea by removing tissue beneath the surface of the cornea.
One of the keys to a successful LASIK procedure is the measurements taken of your eyes. Wavefront-guided LASIK uses a special device to precisely measure the eye’s unique irregularities and variations. Wavefront measuring devices create a very detailed “map” of your eye. These precise measurements enhance the outcome of surgery, resulting in fewer visual side effects and improved quality of vision.
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 reshapes the inner 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 needed is eye drops. Anticipate being in our office about 90 minutes 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 take both an antibiotic drop and a mild steroid drop a few times a day for about a week following the procedure. Some of the advantages of LASIK are little or no postoperative discomfort, waking with good vision the following morning, being back at work quickly, and eye drops are used for less than a week.
LASIK is not recommended for all patients who come for a consultation. Other refractive procedure’s may be recommended. When you meet with us for your consultation, after a thorough examination and discussion, your doctor will be able to tell you which procedure is best for your individual vision needs..

The initials PRK refer to “photorefractive keratectomy”. Photorefractive is the ability of the eye to “refract” or focus light. Keratectomy refers to a removal of a part of the cornea. The PRK process is very similar to LASIK. Both procedures are performed on an outpatient basis. Both use the eximer laser to reshape the curvature of the cornea in order to correct vision for focusing problems.
The shape of the cornea largely determines how light enters the eye and is focused. So, if the curvature of the cornea is too great or too little in relationship to the length of the eye, light cannot be properly focused on the retina. Your doctor will help you select which procedure best meets your vision needs.

VISION ENHANCEMENT PATIENT STORIES
Younger patients enjoy the freedom from glasses and choose Lasik or PRK vision enhancement procedures.
When Paul Nordman decided to have PRK vision enhancement, he hoped to see better and be free of glasses when playing sports. But, it also helps him on the job to no longer have his glasses between him and his work activities. Sarah O’Connor had PRK vision enhancement while on summer break from her classroom full of kids. In addition to her excitement about seeing without glasses, she can now see the expression on each student’s face when they see her for the first time without her glasses.
