OBJECTIVES: The objectives of the study are to show up the healing processes after anterior stromal puncture (ASP) in the cornea using in vivo confocal microscopy (IVCM) and to investigate the efficacy of ASP in the treatment of recurrent corneal erosion (RCE).
METHODS: This is a prospective, non-randomized, consecutive series. Twenty-three eyes of 19 patients diagnosed with RCE were evaluated between March 2020 and January 2022. Outcome measures included age, sex, laterality, etiology of RCE, duration and recurrence of symptoms, additional treatments required, and complications. IVCM was performed on the same day, at 1st week, 1st, and 6th month.
RESULTS: Mean age was 41.5±11.3 years, 63.2% of patients were female and 65.2% of eyes had unilateral involvement. Corneal trauma (56.5%) was the most common cause. Mean follow-up was 21.1 months (range 8–33). At the final follow-up, 69.5% of eyes were symptom free, 17.4% required a second ASP, and 13% needed a third ASP. At the 1st week, the epithelium became intact. An increase in activated keratocytes and dendritic cells (DCs) with beading of nerve fibers was observed. At 1st month, DCs and activated keratocytes were still present. At the 6th month, a scar was left. The superficial and basal epithelial cell formation and subbasal corneal nerve plexus returned to normal.
DISCUSSION AND CONCLUSION: IVCM has a superiority in visualizing cornea at cellular level. After ASP which is a safe, practical, and cost-effective treatment option in paracentral or peripherally located RCE, IVCM may help the surgeon to better observe and understand the post-healing processes and explain the recurrences.
