Abstract
Transepithelial photorefractive keratectomy (Trans PRK) is a relatively new technology for refractive surgery and has shown promising results in myopia correction. The data on hyperopia correction by this method are limited. In this review, we have attempted to understand the outcomes of this technology on hyperopic eyes. There are comparable results with conventional PRK and laser in situ keratomileusis (LASIK) as far as refractive stability, regression rate, predictability, and post-operative complications are concerned. The best results have been obtained in lower hyperopic corrections. In moderate to higher hyperopia, the limited data available show higher regression, unstable visual outcomes, and increased stromal haze. There is a need to evaluate the technology further to understand its success for hyperopic refractive surgery.
Summary
This review was undertaken to understand the data on the outcome of Trans PRK in hyperopia correction and find the causes of lower acceptance of this procedure amongst surgeons and the outcomes in patients. As there are no in-depth analyses of this procedure in hyperopic patients, this review shows that the outcomes of the surgery are good in patients with lower range of hyperopia.
