Outcome of corneal transplantation.

Corneal transplantation is a sight restoring surgery done for corneal blindness. The purpose of this retrospective preliminary study is to analyze the outcome of 54 corneal transplantations (for 32 females and 22 males) done in the Department of Ophthalmology between September 1998 and June 2002. The mean follow-up period was 13 months. Hundred percent (6/6) of the keratoconus (KC) and 85.4% of the nonkeratoconus grafts survived at a mean duration of 7.1 months and 16 months respectively. Seven of the 54 grafts (13%) have failed. The causes of graft failure were graft rejction in 4 and bacterial keratitis in 3 cases. Fifty of the 54 cases (92.6%) had a preoperative visual acuity of < 3/60. As a result of the transplantation, the percentage of blind eyes dropped from 92.6% to 21%. The data in this study confirms that corneal transplantation is a reasonably successful procedure in restoring sight for seleted cases of corneal blindness in Ethiopia.
