Visx Excimer Laser

3-D Active Eye Tracking

ActiveTrak™ is the only system that allows the doctors at Eye Medical Center to track your eye movement in all three dimensions during the treatment, for greater control.

Variable Fixed Beams

Seven variable sized beams give the doctor greater flexibility and allow for faster, smoother treatment with precise corneal shaping.

No Dilation Required

Unlike other systems, with ActiveTrak™ the doctor does not have to dilate your pupils. This means an even quicker recovery time.


ActiveTrak™ is made by VISX®, the name that doctors have trusted in over 2 million procedures.

Excimer Laser Vision Correction, known medically as Photorefractive Keratectomy, is a precise, minimally invasive method of reshaping the cornea. The surgeons at Eye Medical Center use state-of-the-art, computerized excimer lasers to gently remove a thin layer of tissue from the cornea’s surface, flattening the cornea to achieve the desired correction. This reshaping of the cornea helps the eye to focus properly, thus reducing or eliminating the need for eyeglasses and contact lenses. Two variations of this procedure are called LASEK (laser assisted epithelial keratomileusis, and EPI-LASIK).


Prior to the treatment, drops are placed in the eye to numb it, and an instrument is placed in the eye to keep the patient from blinking. The laser treatment itself takes approximately 20-30 seconds and is completely painless. During the 24-48 hours after the treatment, most patients will experience a gritty sensation in the eye as well as some discomfort. Typically the patient will notice improved vision 3-5 days following the treatment.

The results are remarkable. In the U.S. clinical trials for laser correction of nearsightedness, 100 percent of the patients studied experienced improved natural or uncorrected vision. Over 90 percent were returned to 20/40 sight or better - the “driving standard” in most states - and were able to enjoy life and perform most activities without glasses or contact lenses. Two-thirds achieved 20/20 vision.
