LASIK stands for Laser Assisted in-Situ-Keratomileusis. LASIK uses the highly advanced Excimer laser for the correction of nearsightedness, farsightedness and astigmatism.
The purpose of LASIK is to change the curve of the cornea by reshaping it so that light rays are focused more directly on the retina. This brings images into better focus. First, the eye is numbed using an anesthetic eye drop. Next, a thin layer of the front of the cornea is peeled back using a highly precise device called a microkeratome. This protective corneal flap stays attached to the cornea on one side. Then the laser delivers precise pulses of ultraviolet light onto the newly exposed part of the cornea. Each pulse removes a microscopic layer of cornea. Finally, the protective corneal flap is put back into place.
Because of the cornea's natural bonding ability, healing is rapid and does not require stitches and because LASIK is performed under a protective layer of corneal tissue the patient usually experiences very little discomfort. The entire procedure usually takes less than a half hour and most people are able to return to work the next day.
The most significant advantage of LASIK is the rapid recovery of vision, occurring in most cases within 24 hours. In fact many patients will notice a marked improvement in vision by the time they walk out of our center. Your doctor will tell you if you are a good candidate for LASIK when you schedule your personal consultation.
Montgomery Eye Center has a long history of being on the forefront of technology in our field. After painstaking research and study, Montgomery Eye Center chose the VISX Star S4 laser with a Wavescan wavefront mapping system. We believe that this is by far the best laser vision correction system available in the United States.
VISX CustomVue System includes a diagnostic wavefront analysis device (WavePrint™) that maps the entire optical path of the eye. This WavePrint™ Map, called the "fingerprint of your vision," provides Montgomery Eye Center doctor's with precise and detailed information about your vision. This is used to program the laser for precise, personalized treatment.
The WavePrint Map provides information on more than just the corneal surface of the eye. It reveals the way the entire optical system processes light. The WavePrint Map provides a new level of diagnostic information previously unavailable.
Using the WavePrint Map, Montgomery Eye Center doctors can more accurately assess whether patients are good candidates for laser vision correction. The WavePrint Map is becoming the gold standard in vision measurement.
With 3D ActiveTrak™ eye-tracking technology and auto-centering, the laser detects and compensates for small eye movements by guiding the laser beam to keep it centered precisely over the treatment area.
VISX's exclusive ActiveTrak™ is the only system that allows the doctor to track eye movement in all three dimensions. Having the beam centered correctly on the eye at all times helps ensure precise results.
Unlike other lasers with eye-tracking technology, ActiveTrak requires no pupil dilation, leading to an even quicker recovery time.
VISX Star S4 laser systems produce seven variable sized beams, giving Montgomery Eye Center surgeons greater flexibility and allowing for a fast, smooth treatment with precise corneal shaping.
The VISX Exclusive SmartBeam technology adjusts beam size according to treatment, minimizing corneal tissue removal.
The STAR S4 variable beam technology allows Montgomery Eye Center surgeons to treat patients with different laser beam sizes and shapes, determined by each patient's visual needs.
VISX S4 laser system requires a shorter procedure time than many lasers, which enhances comfort and may reduce the risk of postoperative complications.
