PURPOSE: This study was conducted to determine the long-term outcomes of cultivated cell sheet transplantation (CCST), and to clarify risk factors that affected the outcomes.
METHODS: We retrospectively analyzed the medical charts and photographs of 246 consecutive surgeries (162 eyes from 139 patients) that used CCST for treating total limbal stem cell deficiency. Deficiency types included Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (SJS/TEN; n = 80), ocular surface burns (Burn; n = 75), ocular cicatricial pemphigoid (OCP) or pseudo-OCP (n = 58), and others (n = 33). The methods of CCST included 103 cultivated limbal epithelial transplantations (28 autologous, 62 allogeneic, and 13 living-related relatives), and 143 cultivated oral mucosal epithelial transplantations. We analyzed the rate of successful ocular surface reconstruction, clear corneas, and best-corrected visual acuity equal to or better than 20/200.
RESULTS: With a mean observation period of 357 weeks, successful ocular surface reconstruction and clear corneas at last visit were achieved in 65.1% of the patients. Corrected visual acuity equal to or better than 20/200 was achieved in 19.0% of the patients. Eyes with SJS/TEN exhibited worse outcomes compared with the Burn group. Postoperative complications included corneal ulcerations or perforations (18.3%), glaucoma (13.8%), and infections (8.5%). Multivariate analyses using the logistic mixed-effects model indicated that the presence of preoperative corneal epithelial defects was a significant risk factor for postoperative failure.
CONCLUSIONS: In this series, the success rate of CCST after a mean observation period of 357 weeks was 65.1%, and preoperative epithelial defect was the most relevant risk factor.
