Topographic Guided LASIK (Contoura Vision)


Dr Michael George and Dr. Gary Tylock of the Tylock Eye Care & Laser Center are pleased to be the first facility in the state of Texas to perform Topography Guided LASIK also known as “Contoura Vision”. This technology represents the next generation of LASIK refractive surgery. Recently approved by the FDA, Topographic LASIK is the latest and most advanced technology on the market providing the best vision outcomes for eligible candidates. Studies have shown that patients experience better vision quality compared to traditional LASIK treatments even exceeding 20/20 in some cases.


Topographic Technology:


Developed by ALCON, Topography Guided LASIK or Contoura Vision utilizes topographic measurements based on a patient’s corneal irregularity, unlike wavefront technologies that address aberrations in the entire optical path. The treatment incorporates refractive error of the eye and corneal irregularities into a customized laser ablation pattern for myopia and myopic astigmatism. Contoura Vision uses 22,000 data points to fine tune irregularities on the surface of the cornea compared to only 168 with the Wavelight Analyzer. This provides patients the most custom and personalized LASIK treatment available in the United States.

Approval by the FDA for Topography Guided LASIK was based on a multi-center Phase III study using the ALLEGRETTO Wave Eye-Q Excimer Laser System for the treatment of manifest and cornea-based myopic optical errors.  The study demonstrated a number of key results:

  • 92.7% of all study eyes achieved a UCVA of 20/20 or better, and 68.8% of all eyes achieved a UCVA of 20/16 three months after surgery
  • 29.6% of eyes gained at least one line of BSCVA three months after surgery
  • Symptoms traditionally associated with LASIK, such as glare, halos, difficulty driving at night, light sensitivity, and eye dryness, improved after topography-guided LASIK treatment with the ALLEGRETTO WAVE Eye-Q Excimer Laser
  •  Visual symptoms after topography-guided LASIK were generally mild in severity and continued to improve with time; none of the visual symptoms were rated as “marked” or severe” at three months or later post-surgery
  • 98% of the patients said they would have the topography-guided procedure again.
