Corneal surface reconstruction for the chemical injured eye by transplanting autologous cultivated limbal epithelial sheet "Nepic^®".

When using Nepic^®, it is essential to become accustomed to handling the cultivated epithelial sheet on the ring-shaped holder; however, cultivated corneal epithelium transplantation can also be performed without the carrier material, but rather as a sheet. Though the corneal surface appeared smooth and shiny at 7 months postoperatively, we seek to determine whether the epithelial cells on the patient's cornea are of corneal or conjunctival origin without resorting to invasive procedures, such as biopsy.
