Long-Term Outcomes of Epithelial Debridement and Diamond Burr Polishing for Corneal Epithelial Irregularity and Recurrent Corneal Erosion.

PURPOSE: To determine the efficacy of epithelial debridement and diamond burr polishing (ED + DBP) in managing recurrent corneal erosion (RCE) and visually significant epithelial irregularity associated with epithelial basement membrane dystrophy (VS-EBMD).

METHODS: Retrospective, interventional, consecutive case series of all ED + DBP procedures performed between December 1, 2002, and December 1, 2014.

RESULTS: ED + DBP was performed in 91 eyes (66 patients) for the management of RCE and VS-EBMD. Sixty percent (55/91) of the procedures were performed for RCE, of which 65% (36/55) were associated with EBMD and 22% (12/55) with previous corneal trauma. Forty-six percent (42/91) of the procedures were performed for VS-EBMD, including 6 eyes with RCE. RCE resolved after treatment in 97% of eyes with >3 months of follow-up (mean, 33.2 months; range, 3.5-137.6 months). Corrected distance visual acuity (CDVA) and mean topographic astigmatism improved significantly in the 36 eyes treated for VS-EBMD with >1 month of follow-up. In none of the 22 eyes treated for VS-EBMD with >3 months of follow-up did EBMD recur (mean, 31.7 months; range, 3.2-137.6 months). Surgically induced subepithelial haze was present on last follow-up in 9.4% (8/85) of eyes with >1 month of follow-up, but was not associated with decreased final CDVA in any patient.

CONCLUSIONS: ED + DBP is effective in producing long-term resolution of RCE in 95% of treated eyes and significant improvement in CDVA, decreased topographic astigmatism, and long-term resolution of VS-EBMD in 100% of treated eyes.
