Clinical outcomes of transepithelial photorefractive keratectomy versus femtosecond laser assisted keratomileusis for correction of high myopia in South Egyptian population

Mitomycin C application after photorefractive keratectomy in high, moderate, or low myopia: Systematic review and meta-analysis

“…All studies were low risk in random sequence generation except[ 23 ] with high risk and[ 6 18 24 25 26 ] with insufficient data to permit judgment regarding selection bias. All articles were low risk in allocation concealment except four articles,[ 24 32 33 34 ] which have insufficient data making it unlikely to judge. It was unclear to judge the four studies[ 18 32 33 34 ] regarding blinding participants and personnel.…”

Efficacy and safety of single-step transepithelial photorefractive keratectomy with the all-surface laser ablation SCHWIND platform without mitomycin-C for high myopia: A retrospective study of 69 eyes

“…Second, it had a short follow-up period (6 months), which means that we could not assess the myopia regression rate over time [ 27 ]. However, one of the case-series studies on TransPRK in high myopia found that refraction was stable 6 and 12 months after an initial further improvement at 3 months [ 27 ]; moreover, three of the comparative studies on TransPRK in high myopia showed that regression rates at 12 months were similar to those after conventional PRK and/or LASIK [ 16 , 26 , 29 ]. Third, corneal haze measurements were not conducted by the same physician during follow-up; this could have led to differences in diagnosis and grading and may have led to underestimation of the rate of haze.…”

“…For example, the recent randomized trial of Mounir et al . showed that SCHWIND TransTRK and LASIK associated with similar efficacy (80.0% and 80.3%) and safety (95.0% and 95.1%) indices in 156 1:1-randomized patients [ 29 ]. Notably, in nearly all of these studies, the TransPRK protocol included routine treatment with mitomycin-C immediately after ablation.…”
