Abstract Details


To evaluate the clinical features and outcomes of patients with recurrent corneal erosion syndrome (RCES) who underwent combined treatment of phototherapeutic keratectomy (PTK) and peripheral anterior stromal puncture (ASP).


BGN World Tower Eye Clinic, Seoul, South Korea.


Retrospective chart review was conducted for 45 patients (46 eyes) who underwent combined PTK and peripheral ASP for the treatment of large refractory RCES involving visual axis and periphery. PTK was performed with the excimer laser system (Wavelight EX500®; Alcon Laboratories, Fort Worth, TX, USA) in 8 mm treatment zone at a depth of 5 μm. Peripheral ASP was made at 360 degree peripheral area outside 8 mm PTK ablated zone with bent needle tip. Outcome measures included demographics, history of corneal trauma, prior ocular history, additional treatments needed, and complications.


Fifty three percent of patients (24/45) were men, 47% (21/45) were women. The mean age of patients was 43.24 (± 12.8 SD) years. Eighty six percent of patients (39/45) had a prior history of trauma, 13% (6/45) had prior refractive surgery. Mean follow-up period was 26 months (range: 1-54 months). At final follow-up, 87% (40/46) of eyes were symptom-free and 13% (6/46) experienced recurrences. All recurred patients were not required additional treatment except for temporary therapeutic contact lenses.


Combined PTK and peripheral ASP were effective in the treatment and prevention of recurrence in the RCES of large lesion size and refractory to conservative measures.
