Base Curves of Bandage Contact Lenses and Their Effects on Post Trans-PRK Vision and Pain

Base Curves of Bandage Contact Lenses and Their Effects on Post Transepithelial Photorefractive Keratectomy (Trans-PRK) Vision and Pain： A Prospective Randomized Clinical Trial

The objective of this study was to investigate the impact of employing bandage contact lenses with a base curve of 8.4 mm versus 8.8 mm on visual recovery following Trans-PRK in patients characterized by steep corneas and high myopia.

Comparing two kind of bandage lenses in the contralateral eyes of the same individual following Trans-PRK may enable the derivation of reliable conclusions regarding the optimal choice for bandage lenses after Trans-PRK.
