Abstract

Purpose:

To analize changing trends in indications and surgical techniques of corneal transplantation at an ophthalmological tertiary referral center in Colombia over a 7 year period.

Methods:

A retrospective analysis was performed of medical records from patients who underwent corneal transplantation surgeries at Fundación Oftalmológica de Santander (FOSCAL) in Bucaramanga, Colombia, between August 2004 and August 2011.

Results:

During this period from a total of 450 corneal transplants performed, we had access to 402 medical records (89.4%). The patients’ mean age was 55. Leading indications were: pseudophakic/aphakic bullous kerathopathy (PBK/ABK) (34.6%), corneal scar (15.7%), active infectious keratitis (14.4%) and keratoconus (12.7%). During the first period (2004-2007) PBK/ABK was the leading indication, followed by stromal opacities and keratoconus. During the second period (2008-2011) PBK/ABK remained the leading indication. Infectious keratitis, however, became the second most common indication. Stromal opacities and keratoconus, moved to third and fourth, respectively. All transplants performed in the first period (2004-2007) were penetrating keratoplasties. In the second period (2008-2011) 18.7% of the procedures were performed using the Descemet’s stripping automated endothelial keratoplasty technique (DSAEK).

Conclusions:

Similar to other international results, PBK/ABK was the leading indication for corneal transplantation at our institution. Keratoconus is becoming a less common indication for keratoplasty in our institution. Infectious keratitis remains a frequent indication for corneal transplantation in this geographical area. In our institution we started performing DSAEK in 2009, and it is emerging as the procedure of choice in corneal diseases that involve only the endothelial layers.
