    Abstract:
    PURPOSE: To compare the safety, efficacy, and clinical outcomes of simple limbal epithelial transplantation (SLET) with conjunctival-limbal autologous transplantation (CLAU) in severe unilateral ocular chemical burns. MATERIALS AND METHODS: Twenty patients of unilateral chronic ocular burns with more than 270° limbal stem cell deficiency and a healthy fellow eye were divided into two groups - ten patients of Group A underwent SLET while ten patients of Group B were operated for CLAU. Patients were followed up for 6 months and assessed for a stable epithelialized ocular surface, extent of reduction in vascularization and forniceal reconstruction, improvement in corneal clarity and visual acuity. RESULTS: A stable epithelialized corneal surface was obtained in all patients, with a significant reduction in the mean clock hours of vascularization in both the groups (P < 0.001). The mean symblepharon score showed a statistically significant reduction from 1.80 ± 1.14 to 0.30 ± 0.63 in Group A and 1.70 ± 1.06 to 0.15 ± 0.24 in Group B at 6 months. Corneal clarity, as well as best-corrected visual acuity, showed a statistically significant improvement in both the groups. CONCLUSION: Both the procedures, SLET and CLAU, were equally effective in achieving a stable ocular surface, forniceal reconstruction, and regression of corneal vascularization. The requirement of minimal donor tissue in SLET makes it a preferred option over CLAU in cases of uniocular chronic ocular burns.
