Arms Assigned Interventions
Experimental: Limbal Stem Cell Transplant
The cornea is debrided of all superficial fibrovascular tissue and the cultivated stem cell graft is glued onto the cornea.
Procedure: Cultivated limbal stem cell graft transplantation
A limbal biopsy taken from the contralateral good eye in cases of unilateral disease or from a living related or cadaveric donor in cases of bilateral disease. The limbal stem cells from the biopsy are cultivated until a sheet of cells measuring approximately 12mm in diameter is obtained. This is then ready for transplantation onto the diseased eye.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patients suffering from LSCD IIa and IIb. Those suffering from IIc may be included once inflammation has subsided and cornea can be staged as IIb.
  • Age: ≥ 18 years
  • Absence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial.
  • Women of child-bearing potential should use adequate contraception prior to study entry and for the duration of study participation

Exclusion Criteria:

  • Subjects who are pregnant or lactating
  • Subjects who have sensitivity to drugs that provide local anesthesia
  • Subjects suffering from active infection of the external eye
  • Medical conditions that prohibit the use of systemic immunosuppression (in cases of allogenic transplantation)
