Evaluation of Anterior Stromal Puncture Using Nd:YAG Laser for Refractory Recurrent Corneal Erosion

ABSTRACT

PURPOSE: To evaluate the clinical results of anterior stromal puncture (ASP) using neodymiumyttrium-aluminum-garnet (NdYAG) laser for refractory recurrent corneal erosion (RCE). METHODS: Ten eyes of eight patients with RCE showing poor response to conservative therapy who were treated with NdYAG laser ASP and followed up for at least 4 months were studied. The cause and duration of erosions, times, and total energy of the laser were recorded. The preoperative and postoperative best corrected visual acuity (BCVA), intraocular pressure, complications, and recurrence were reviewed. RESULTS: The mean follow-up time was 9.6 months. The laser energy setting was 0.2 or 0.3 mJ per shot. The average total laser energy was 6.2 mJ. Two of 10 eyes received another NdYAG laser treatment. All 10 eyes were successfully treated and had no recurrence after the operation during follow-up. Postoperative BCVAs were equal to or better than the preoperative BCVAs. No significant complications except faint corneal haze were observed. CONCLUSIONS: NdYAG laser ASP is an effective and safe procedure to treat refractory RCE in short-term follow-up.
