About this study

The objective of the clinical investigation presented to is to verify predictions of post-operative PTK-PRK refractive outcome made by the EpiMaster application software by comparing these to post-operative clinical data after routine PTK-PRK treatments.

The EpiMaster application software is not used in this clinical investigation, consequently, it is a merely observational investigation.
