Abstract:
Descemetorhexis without endothelial keratoplasty (DWEK) is an innovative corneal intervention and potentially effective against Fuchs endothelial corneal dystrophy (FECD). We aimed to conduct a systematic review and meta-analysis on the outcomes of DWEK, associated or not with phacoemulsification (PKE) and rho-kinase inhibitor (RHOKI) in FECD. Method: PubMed, Cochrane Library, Embase, ClinicalTrials.gov, and Science Direct were searched for studies until November 29, 2020. We performed random-effects meta-analyses and meta-regressions, stratified by the type of intervention and descemetorhexis size (PROSPERO CRD42020167566). Results: We included 11 articles (mainly case series, both prospective and retrospective), representing 127 eyes of 118 patients. DWEK globally improved visual acuity (effect size = −1.11, 95% confidence interval, −1.70 to −0.52, P 〈 0.001) and pachymetry (−1.25, −1.92 to −0.57, P 〈 0.001), without significant effects on endothelial cell count (−0.59, −2.00 to 0.83, P = 0.419). The 3 types of interventions (ie, DWEK ± RHOKI, DWEK ± PKE, and DWEK ± PKE ± RHOKI) improved visual acuity and pachymetry in FECD. A descemetorhexis size ≤4 mm improved visual acuity (−0.72, −1.29 to −0.14, P 〈 0.001) and pachymetry (−0.68, −0.98 to −0.38, P 〈 0.001), whereas 〉 4 mm did not. Overall, DWEK failure (ie, the prevalence of EK after DWEK) was 17% (7%–27%, P 〈 0.001), with 4% (0%–8%, P = 0.08) for a descemetorhexis size ≤4 mm. Conclusions: Despite the lack of comparative studies, DWEK seemed to improve visual acuity and pachymetry in early stages of FECD. A descemetorhexis size ≤4 mm was associated with the best visual outcomes and pachymetry.
