PURPOSE: To investigate the efficacy and safety of secondary surgical intervention of combined phototherapeutic keratectomy (PTK) with alcohol delamination and peripheral anterior stromal puncture (ASP) for refractory recurrent corneal erosion (RCE).
METHODS: This retrospective comparative study defined refractory RCE as cases persisting for more than 6 months after primary surgical intervention. A total of 115 eyes from 115 patients with refractory RCE, treated either with (n = 92) or without (n = 23) the secondary surgical treatment combining PTK and ASP between January 2021 and January 2023, were included. The Kaplan-Meier survival analysis method was used to determine the intervention's efficacy.
RESULTS: The mean age was 34.4 ± 10.8 years, with a predominance of male patients (60%). Over a follow-up period exceeding 1 year, the recurrence rate was markedly lower at 27.2% in the group undergoing secondary surgical treatment compared with 69.6% in those receiving conservative treatment. Kaplan-Meier survival analysis revealed significantly reduced recurrence rates in the surgical group versus the conservative treatment group (log-rank test, P = 0.007). Notably, 96% of recurrences in the surgical cohort occurred within the first 6 months postintervention, with no recurrences observed after 9 months. At the final follow-up, 12% necessitated further surgical procedures 6 months after the secondary intervention. The study reported no significant surgical complications.
CONCLUSIONS: The secondary surgical approach combining PTK with alcohol delamination and ASP presents a viable and safe treatment alternative for patients with refractory RCE, demonstrating a significant reduction in recurrence rates.
