Topography-Guided LASIK for Treatment of Myopia and Myopic Astigmatism
Narrative Responses:
Purpose
To evaluate topography-guided LASIK (T-CAT) for the treatment of myopia and myopic astigmatism.
Methods
One-year non-randomized FDA study of 249 eyes of 212 subjects treated with T-CAT using an excimer laser (ALLEGRETTO WAVE® Eye-Q ) for up to -9.00 D of myopia with up to 6.0 D of astigmatism.
Results
At 3 months, UCVA was 20/20 or better in 93% of eyes, 20/16 or better in 69%, and 20/12.5 or better in 32%. 39% of eyes gained 1 or more lines of BSCVA; 1.6% lost 1 line of BSCVA; and none lost more than 1 line of BSCVA. Contrast sensitivity improved; most visual symptoms were unchanged or improved; and patient satisfaction was high. Dry eye was the most commonly reported complaint.
Conclusion
T-CAT produces excellent UCVA, improves BSCVA, and reduces visual symptoms with a high level of patient satisfaction and no significant safety concerns.
