  • Abstract
  • Look Inside

We evaluated the long-term outcome of kerato-plasty for thermally or chemically injured cornea. This study included 17 eyes treated by penetrating keratoplasty and one eye by lamellar keratoplasty. We divided the cases into two major categories regarding the ocular surface manifestations. Cases with corneal scarring with minimal conjunctival invasion into the cornea were assigned to Type A. Those with corneas completely covered by invaded conjunctiva were assigned to Type B or C. Eyes in Type C underwent conjunctival transplantation prior to keratoplasty.

The cornea graft remained transparent in 5 out of 7 eyes in Type A, for as long as 7 years. In all of 11 eyes in Type B and C, epithelial defects devel-oped after keratoplasty and resulted in failed grafts within one year. The finding suggests that conven-tional keratoplasty is to be avoided, for the time being, in corneal burn with complete invasion of the conjunctiva.
