Purpose
To describe the indications and techniques of corneal grafting in a tertiary institution in a middle-sized city in Colombia.
Methods
A retrospective review of surgical reports and medical records of patients undergoing keratoplasty from January 2012 to December of 2016.
Results
A total of 346 eyes from 316 patients were included. The first three indications for keratoplasty were: bullous keratopathy (BK) with 46.2% of the cases, active infectious keratitis (22.3%) and the group of corneal dystrophies and degenerations, including Fuchs’ endothelial dystrophy (9%). Keratoconus was in the sixth place (4.9%). 73.3% of the procedures were penetrating keratoplasties (n = 255), 21.7% posterior lamellar (n = 75) and 3.5% anterior lamellar (n = 12). While in 2012, 25 cases of endothelial grafts were performed, only 13 were done in 2016.
Conclusions
BK was the first cause of keratoplasty with almost half of the cases, and keratoconus was relegated to sixth place with less than 5%. In comparison, in a study from eye banks from the US, BK was the second and keratoconus was the third indication for corneal grafts. The frequency of endothelial lamellar techniques in our institution decreased from 2012 to 2016. This could have been related to both the long time that the patients had to be on a waiting list, which made them unsuitable candidates for this technique, due to stromal fibrosis, and to the fact that surgeons of our institution had less experience with posterior endothelial grafting than with penetrating keratoplasties.
