Objective
To study the effect of epithelial cells transplantation from the limbus of the contralateral cornea in patients with keratitis due to herpes simplex.
Methods
We took specimens of limbal epithelial cells from the healthy contralateral eyes of seven patients with unilateral keratitis due to herpes simplex. Limbal epithelial cells was transplanted to the denuded corneal surface of the damaged eye after superficial keratectomy to remove fibrovascular ingrowth. The mean (B±SD) follow-up period was 15B±2 months.
Results
Complete reepithelialization of the corneal surface occurred within two to four days of transplantation in all six eyes receiving transplants. By one month, the ocular surface was covered with corneal epithelium, and the clarity of the cornea was improved. In five of the seven eyes receiving transplants (71 percent), the mean visual acuity improved from 20/112 to 20/35. No patient had recurrent neovascularization or inflammation in the transplanted area during the follow-up period.
Conclusions
Transplantation of autologous limbal epithelial cells is a simple and effective method of reconstructing the corneal surface and restoring useful vision in patients with unilateral deficiency of limbal epithelial cells.
