Contoura or T-CAT stands for Topography-guided Custom Ablation Treatment. Contoura (T-CAT) is the LASIK at its highest level of precision, perfected over 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 analysis of the cornea, VARIO Topolyzer gathers 22,000 reference points which are analyzed to detect the most subtle abnormalities of the 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.
In the FDA study, Contoura (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.
Dr. Paul C. Lee, at CCRS, has been performing Contoura/T-CAT LASIK since its FDA approval in 2015.
