Prospective Study of Topography-Guided LASIK for Myopia: 12-Month Clinical Results
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.
