e Silva FB, et al. - In the patients with corneal transplants (PKP), who underwent topography-guided photorefractive keratectomy (TG-PRK) with mitomycin C (MMC) the visual acuity and keratometric and aberrometric changes were assessed. The best spectacle-corrected visual acuity (BSCVA) improved notably, the lines of vision increased, and astigmatism, corneal best-fit sphere, mean keratometry, corneal thickness, corneal root mean square total, and corneal spherical aberrations decreased, 12 after the operation. Results demonstrated that in order to correct post-PKP cases having irregular astigmatism with elevated higher-order aberrations, TG-PRK with MMC was good alternative.
