Contoura LASIK in Los Angeles

Free Consultation

First to perform VisuMax-Contoura LASIK in the U.S.

Contoura LASIK or T-CAT (Topography-guided Custom Ablation Treatment) represents LASIK at its highest level of precision and reflects 20 years of laser vision correction experience and knowledge.

This technology combines the two most essential concepts in laser vision correction: wavefront and topography. During the corneal analysis, VARIO Topolyzer collects 22,000 reference points that are analyzed to detect the most subtle abnormalities unique to each cornea. This information is then seamlessly transferred to WaveLight EX500 excimer laser for extremely precise laser sculpting of the cornea. The result is true customization in laser vision correction that addresses the most subtle imperfections found in each eye.

It has been shown that more people see 20/20 or better with Contoura LASIK than with standard LASIK. Furthermore, many people achieve incredible clarity and sharpness that allow them to see 20/15 or better.

Dr. Paul C. Lee, at CCRS, has been performing Contoura LASIK (T-CAT) since its FDA approval in 2015.


In the FDA study, Contoura LASIK (T-CAT) results have exceeded other LASIK procedures, with the highest rate of vision better than 20/20, the highest rate of patients seeing better than with their glasses or contact lenses, and the highest rate of patient satisfaction. Alcon press release

Contoura LASIK is also known as Topography-guided custom ablation treatment or TCAT . In this custom LASIK, exact and detailed information of the patient’s cornea is obtained using a topography device called Topolyzer. This information is used to treat very subtle abnormalities that exist in the human cornea in an attempt to bring out the best visual outcome.
In Contoura LASIK, additional analysis is performed to determine subtle abnormalities that exist in the human cornea. The result of this detailed evaluation is then incorporated into the treatment plan giving the patient the most advanced laser vision correction. In an FDA study, it was found that people who had Contoura LASIK had a higher chance of seeing better than 20/20 than Wavefront LASIK.
Contoura LASIK costs $2500 per eye.
