Topography-guided custom ablation treatment PRK showed good outcomes in eyes with low to moderate myopia.
Forty eyes of 25 patients with low to moderate myopia, with or without astigmatism, were included in a retrospective study. They underwent topography-guided custom ablation treatment (T-CAT) PRK with the Alcon WaveLight EX500 excimer laser platform. Patients had no previous ocular surgery, refractive stability for at least 1 year, corrected distance visual acuity (CDVA) of 20/25 or better, spherical equivalent refraction of less than 6 D, refractive astigmatism of less than 3 D, and age
