Transepithelial cross-linking improves corrected distance visual acuity, corneal flattening
Transepithelial corneal collagen cross-linking resulted in significant corneal flattening and improved corrected distance visual acuity at 6 months in patients with keratoconus, according to a study.The prospective clinical trial included 30 eyes of 25 patients with keratoconus who underwent transepithelial corneal collagen cross-linking.
