Your Today's Vision surgeon utilizes the VISX Star S4 cool beam Excimer laser which is most popular with LASIK surgeons throughout the United States. VISX is the leading manufacturer of Excimer lasers in this country.

The VISX Star S4 features an expanded treatment zone to 8 mm which helps reduce or prevent night-time glares and halos in patients with large pupils. More importantly, it has sophisticated eye-tracking capabilities which help ensure your laser vision treatment is completed to your surgeon's specifications.

Other special elements of the VISX Star S4 include:

• A seven-beam overlapping profile to treat a larger area in less time.
• It does not require dilation.
• It can treat a higher degree of nearsightedness.
• The VISX was developed exclusively for ophthalmologic purposes.
• The Active Trak eye-tracker employs infrared cameras that record eye movements before every pulse.
• The Active Trak follows not only the left and right movements of the eye, but the up and down movements that occur with breathing.

The VISX Star S4 at the Laser Eye Institute of Houston has all the upgrades to accommodate Wavefront-guided LASIK. The CustomVue system incorporates sophisticated data from the WaveScan to help produce a more precise LASIK surgery.
