Among the most technologically advanced systems used in laser lasik houston is the Allegretto Wave Excimer Laser. Approved by the FDA in 2003, it was first utilized in Houston, and has been extremely effective in cornea correction.

Laser lasik houston has used the Allegretto in over 40,000 eye corrective surgeries and it is fitting to illustrate how this system operates to achieve its high success rate.

The Allegretto is a system that does not have to rely on peripherals to determine the size and scan of the treatment beam. Instead, this software is influenced solely by the data that is directly inputted by a number of sources to optimize treatment options. In addition, the Allegretto can produce true optical zones while conserving tissue and eliminating the possibility of night vision problems. This was true of prior laser treatment in which the optical zone was centered on the front of the cornea.

What is the optical zone? The optical zone is that portion of the cornea that has been corrected by the laser. A larger optical zone is especially important for night vision and for patients who have very large pupils. If the pupil is larger than the optical zone, the patient may experience poor peripheral vision, poor night vision, and a higher than normal incidence of glare. Thus, individuals who have had laser surgery and are still bothered by sunlight and glare is a perfect example of why former laser techniques were ineffective.

Having the Allegretto's advanced technology has taken the laser lasik houston surgeon in a new and innovative direction.

In addition, the laser lasik houston surgeon allows for active eye tracking technology precise real-time tracking of the Allegretto's laser beam, to ensure accurate placement of each pulse. The high-speed scanning component in the Allegretto also allows for the laser to deliver 200 laser pulses per second. This achieves even distribution of laser energy over the treatment zone on the cornea.

For the laser lasik houston surgeon, the Allegretto has the ability to correct aberrations, and the laser treatment combined with the scanning capability enables the surgeon to correct the refractive errors and other aberrations utilizing a single process. Thus, once the surgery is complete, there is no need for further corrective surgery in the future.

After surgery your vision will stabilize within one or two weeks. But it may take a several months to continue to improve. You may experience glare and night blindness may during this time. Risks with Lasik laser eye surgery are visual aberrations especially in low light, over or under-corrected and additional surgery enhancement may be needed, regressive in the treatment this is uncommon, dry eye symptom which may require medication for tear production, in rare cases vision may worsen that cannot be corrected. You should contact your eye doctor immediately if any of these conditions occur or worsen.
