Safety Outcomes

AIM: To compare the efficacy and safety of penetrating keratoplasty (PK) and deep anterior lamellar keratoplasty (DALK) in the treatment of stromal corneal dystrophy. METHODS: A systematic review and Meta-analysis was conducted for studies comparing visual acuity [best-corrected visual acuity (BCVA) (LogMAR)] and corneal endothelial cell count (ECC) as well as safety outcomes of DALK and PK surgeries, including graft-related outcomes and intraoperative and postoperative complications. Embase, PubMed, and Google Scholar were searched for eligible studies until June 2019. Continuous and dichotomous variables were expressed as weighted mean difference (WMD) and risk ratios (RRs), respectively, along with their respective 95% confidence intervals (CIs). RESULTS: Five comparative studies recruiting 350 patients with macular and/or lattice corneal dystrophy (59.71% males) were eventually included. No significant differences were noted in the mean BCVA after both types of surgeries. However, following DALK procedures, corneal ECC was significantly higher two years postoperatively (WMD=401.62 cell/mm2, 95%CI: 285.39-517.85, P<0.001), and graft and endothelial rejection rates were significantly lower (RR=0.30, 95%CI: 0.14-0.64, P=0.002; RR=0.09, 95%CI: 0.02-0.46, P=0.004, respectively) when compared to patients undergoing PK procedures. However, DALK procedures were associated with increased risks of intraoperative Descemet’s membrane perforations and postoperative double anterior chamber (All P<0.001). CONCLUSION: DALK procedures are relatively more efficacious over the follow up periods with better safety outcomes than PK in patients with stromal CDs, conerning rejection and better visual outcome.

Important Shift

Purpose: The aim of this study was to report the 12-year longitudinal trends in indication and corneal transplantation techniques in France from 2004 to 2015. Results: The records of all corneal transplantations performed from 2004 to 2015 in France were retrospectively reviewed. The patient indications and types of transplant performed were analyzed. A total of 46,658 corneal transplantations were performed between 2004 and 2015, with 34,187 (73.3%) penetrating keratoplasty and 10,452 (22.4%) lamellar keratoplasty. The leading surgical indications were secondary endothelial failure (24.3%), keratoconus (18.8%), regraft (13.5%), and Fuchs endothelial corneal dystrophy (15.1%). Endothelial keratoplasty became the preferred technique for endothelial diseases and deep anterior lamellar keratoplasty the preferred technique for keratoconus, surpassing penetrating keratoplasty in 2013. Conclusion: Secondary endothelial failure is the top indication for performing a keratoplasty over the 12-year period. There was a shift from penetrating keratoplasty to endothelial keratoplasty performed for Fuchs endothelial corneal dystrophy and secondary endothelial failure, and to deep anterior lamellar keratoplasty, performed for keratoconus. This highlights an important shift in managing corneal diseases toward the application of selective and more conservative surgeries and changes in indications in corneal transplantation.
