Table 2. Distribution of diagnosis and rate of graft failure related to each condition at 1y postoperative.

Diagnosis	No. of eyes	Failure
Keratoconus	63	3 (4.76)
Pseudophakic bullous keratopathy	31	14 (45.16)
Trauma	6	2 (33.33)
Herpes simplex virus	10	3 (30.00)
Non herpetic corneal ulcer	9	6 (66.67)
Non herpetic corneal scar	4	4 (100)
Corneal dystrophy	11	4 (36.36)

In the RSS both keratoconus and corneal dystrophy have the same score, according to the probability of graft failure shown by the ACGR^[1]. However, the rate of failure in our sample for each condition is very different. Among the 4 cases having corneal dystrophy (Fuchs endothelial dystrophy) as primary diagnosis showing graft failure at 1y, 1 case had 4 quadrants of corneal neovascularization, and another case had a previous failed graft with chronic uveitis and high intraocular pressure, making reasonable to consider that it may be the features of a certain condition what is related to graft failure, rather than the diagnosis itself.
