Primary Outcome Measures:
  • Ocular surface status (signs of limbal deficiency and immunopathological markers) [ Time Frame: Three years ]

Enrollment: 19
Study Start Date: January 2008
Study Completion Date: November 2011
Primary Completion Date: April 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Cultivated limbal transplantation Procedure: Cultivated limbal transplantation
Cultivated corneal epithelial stem cell transplantation. Autograft, Living related allograft, and Cadaveric allograft

Detailed Description:
Ocular surface damage caused by severe ocular surface diseases, particularly thermal and chemical burn or Stevens-Johnson syndrome result in corneal epithelial defect, corneal vascularization, corneal conjunctivalization and loss of transparency. Corneal limbal stem cell transplantation has been demonstrated to improve the outcome of ocular surface reconstruction. However, the conventional management of allograft limbal transplantation generally has unsatisfactory outcome because of high risk of rejection and requires long-life immunosuppressive medications.
