PURPOSE: To evaluate the efficacy of automated lamellar therapeutic keratoplasty (ALTK) for the management of anterior corneal stromal scarring caused by trachoma. METHODS: Seventeen cases of trachomatous keratopathy that were treated by ALTK were retrospectively evaluated. The main outcome measures were uncorrected visual acuity, best-corrected visual acuity (BCVA), keratometry, pachymetry, time to epithelialization, graft clarity, and complications, if any. RESULTS: The mean age of the patients was 50.3 ± 14.1 years. Five of the 17 cases had Salzmann nodular degeneration. The mean decimal BCVA was 0.06 ± 0.05 preoperatively, which improved to 0.41 ± 0.16 at 12 months, and 12 eyes (70.6%) had a postoperative BCVA of 6/18 or better. The median epithelialization time was 6 days (range, 1-38 days). Persistent epithelial defect developed in 6 eyes, and 1 eye developed graft infection. CONCLUSIONS: Anterior stromal corneal scarring caused by trachoma can be effectively treated with ALTK. However, occurrence of persistent epithelial defects may complicate the success of this surgery.
