PURPOSE: To perform a systematic evaluation of the efficacy and safety of loteprednol etabonate (LE) 0.5% versus fluorometholone (FML) 0.1% for treating patients after corneal refractive surgery with the aim of providing an evidence-based rationale for clinical drug selection.
METHODS: Electronic databases (PubMed, EMBASE, Cochrane Library, Web of Science, WanFang, and CNKI) were searched (from inception to December 2021) for comparative clinical studies that evaluated LE versus FML treatment for post-corneal refractive surgery patients. Meta-analysis was performed using the RevMan 5.3 software. The pooled risk ratio (RR) and weighted mean difference (WMD) with corresponding 95% confidence interval (CI) were calculated.
RESULTS: Nine studies with a total sample size of 2677 eyes were included in this analysis. FML 0.1% and LE 0.5% produced a similar incidence of corneal haze within 6 months after surgery (P = 0.13 at 1 month, P = 0.66 at 3 months, and P = 0.12 at 6 months). There was no statistically significant difference between the two groups in terms of the mean logMAR postoperative uncorrected distance visual acuity (WMD: – 0.00; 95% CI: – 0.01 to 0.00; P = 0.29) and spherical equivalent (WMD: 0.01; 95% CI: – 0.01 to 0.03; P = 0.35). LE 0.5% appears to have a higher tendency to reduce the incidence of ocular hypertension compared FML 0.1%, but there was no statistical significance (RR: 0.63; 95% CI: 0.27 to 1.50; P = 0.30).
CONCLUSION: This meta-analysis demonstrated that LE 0.5% and FML 0.1% had comparable efficacy in preventing corneal haze and corticosteroid-induced ocular hypertension, with no difference in visual acuity in patients after corneal refractive surgery.
