Why carry out this study?

Within the last 25 years, there has been a lack of research published pertaining to the visual outcomes of patients receiving photorefractive keratectomy (PRK) enhancement after primary PRK. The study aims to examine the safety, efficacy, and predictability of PRK enhancement following primary PRK.

The study asked, “What are the visual outcomes of patients undergoing PRK enhancement after primary PRK?”

What was learned from the study?

When compared to the published studies, our results show that modern PRK enhancement after primary PRK has improved refractive outcomes and visual acuity.

PRK enhancement following PRK is not FDA approved; however, our study shows that it meets or exceeds the FDA safety, efficacy, and refractive predictability requirements for refractive error correction.
