Optical Coherence Tomography-Guided Transepithelial Phototherapeutic Keratectomy for Central Corneal Opacity in the Pediatric Population

Figure 1

Optical coherence tomography-guided transepithelial phototherapeutic keratectomy for central corneal opacity in the pediatric population. Corneal topography before and after phototherapeutic keratectomy. (a) Preoperative corneal topography of a 9-year-old female who developed corneal scarring after an episode of herpes simplex virus keratitis. Central irregularity is quite apparent. The preoperative best spectacle-corrected visual acuity was 20/80. (b) Corneal topography of the same patient from A 6 months after phototherapeutic keratectomy. There has been an improvement in central corneal regularity and in the topographic indices. The best spectacle-corrected visual acuity improved to 20/30.
