In a previous study comparing alcohol with mechanical debridement in patients who underwent bilateral PRK, results showed a trend toward a quicker visual rehabilitation in the alcohol-treated patients along with equivalent safety and efficacy. 23 In another similar study, a faster and more circumscribed epithelial removal was achieved when using alcohol rather than a scalpel blade. 9 There was also a trend toward more haze in the mechanically scraped patients over the course of the same study.
