Successful deep anterior lamellar keratoplasty following multiple failed limbal transplantations for chronic ocular burns.

A 9-year-old girl with severe unilateral ocular surface disease due to limbal stem cell deficiency following chemical injury underwent autologous cultivated limbal epithelial transplantation (CLET) twice in her right eye that failed to improve the condition of the ocular surface. On both occasions, limbal biopsies were obtained from the unaffected left eye. Since further attempts at CLET were not considered to be safe, deep anterior lamellar keratoplasty (DALK) was performed instead.
