About the Lasers
At the present time, more then 85% of all laser vision correction performed in the United States utilize three excimer laser platforms: The VISX Star S4 Active Trak with WaveScan "Wave Print Mapping", the Bausch & Lomb Technolas 217 with the Zyoptix Platform; and the Alcon LadarVision with LadarWave Wavefront technology. All of these lasers yield outstanding results and are used by Dr. Cabler at the Laser Eye Institute in Bellaire, TX. Since each laser has subtle advantages, Dr. Cabler selects the appropriate laser depending on the patientís individual needs.
All lasers are:
- Now approved to treat nearsightedness, farsightedness and astigmatism.
- Each has sophisticated eye-tracking capabilities to minimize the impact of eye movements during the LASIK procedure.
- Are approved to treat up to a larger 8mm optical zone, which is important in helping certain individuals with larger pupils to improve their night vision and diminish the possibility of halos at night.
The VISX Star S4 Active Trak utilizes a broad laser beam that is broken into seven overlapping beams to deliver a clean, smooth treatment. The LadarVision utilizes laser energy applied in a small diameter spot (flying spot laser) moving randomly through the treatment zone also providing a very smooth treatment surface.
The official treatment parameters established by the FDA for VISX Star S4 Active Trak are as much as 5 diopters of farsightedness with up to 4 diopters of astigmatism. A diopter is defined as the unit of measure of the power of a lens. This laser is also approved to treat up to 14 diopters of nearsightedness with up to 5 diopters of astigmatism.
The official treatment parameters established by the FDA for the LadarVision are up to 6 diopters of farsightedness with up to 6 diopters of astigmatism. This laser is also approved to treat up to 10 diopters of nearsightedness with up to 4 diopters of astigmatism.
The Bausch & Lomb Technolas 217 is approved to treat up to 12 diopters of myopia and up to 3 diopters of astigmatism and has been approved to treat hyperopia as well. The Technolas 217 received the highest FDA rating of all excimer lasers presently approved in the United States.
All lasers have many other built-in features to help guarantee the accuracy and safety of the LASIK procedure.
