This retrospective study presented the incidence rate, features, and outcomes of infectious keratitis following PRK in a tertiary hospital over a 13-year period.
In our center, the post-PRK infectious keratitis incidence rate was reported as 0.018%. which was within the range reported in former studies (Table 6) [9,10,11,12,13].
There is debate concerning the rate of infectious keratitis after photorefractive surgeries when comparing PRK and LASIK [14, 15]. Rojas et al. reported a 5.7-times higher incidence rate of infectious keratitis in patients undergoing surface ablation compared to those undergoing LASIK [15]. The same group [16] reported a decrease in the incidence of post-PRK infectious keratitis from 0.2 to 0.066% when tobramycin and…
