To evaluate Topography-Guided LASIK (T-CAT) for the treatment of myopia and myopic astigmatism.

One year, non-randomized, prospective study of 249 myopic eyes of 212 subjects using the T-CAT algorithm on the Allegretto Wave Eye-Q 400 Hz excimer laser.  All eyes were targeted for plano using topography and refraction for treatment planning.

UCVA was > 20/20 in 93% of eyes, > 20/16 in 65%, and > 20/12.5 in 34%.  40.4% of eyes gained > 1 lines of BSCVA; 2.2% lost 1 line of BSCVA. Contrast sensitivity improved; most visual symptoms were unchanged or improved; and patient satisfaction was high.

At 1 year, primary T-CAT LASIK produces excellent UCVA, improves BSCVA, and reduces visual symptoms with a high level of patient satisfaction and no significant safety concerns.
