Correlations between risk factors and haze after PRK identified

14:00 EDT 8 Aug 2017 | Healio

A large cohort study investigating factors associated with the development of haze after PRK found significant correlations with hyperopia, high myopia and high astigmatism. Longer mitomycin C application and laser removal of the epithelium rather than alcohol debridement, however, may have a beneficial effect on haze prevention. A total of 7,535 eyes of 3,854 patients who underwent PRK over 2 years were retrospectively reviewed. The epithelium was removed with the application of alcohol or by laser ablation. All PRK procedures were performed with the WaveLight EX200 Allegretto Wave laser (Alcon). MMC was applied for between 20 and 60 seconds.
