Abstract: 

Purpose: To report changing trends in indications and techniques of corneal transplantation in Iran.
Methods: We reviewed eye bank records of 47, 129 patients who had undergone corneal transplantation between 2006 and 2013 at different eye centers throughout Iran.
Results: The most common indication for corneal transplantation was keratoconus (KCN, n=21, 350 eyes, 45.3%), followed by bullous keratopathy (BK, n=8, 566 eyes, 18.2%), corneal opacity and scar (COS, n=7, 158 eyes, 15.2%), graft failure (n=3, 252 eyes, 6.9%), corneal dystrophies (n=2, 553 eyes, 5.4%), and infectious keratitis (n=2, 238 eyes, 4.7%). Over the study period, there was a significant increase in the frequency of BK (P=0.001) and graft failure (P=0.025), and a significant decrease in the relative frequency of COS (P=0.012). The prevalence of KCN (P=0.172), infectious keratitis (P=0.107), and corneal dystrophies (P=0.836) remained unchanged. The most common technique of corneal transplantation was penetrating keratoplasty (PKP, n=33, 476 eyes, 71.0%), followed by deep anterior lamellar keratoplasty (DALK, n=8, 363 eyes, 17.7%), Descemet’s stripping automated endothelial keratoplasty (DSAEK, n=3, 516 eyes, 7.5%), tectonic (n=1752, 3.7%), and keratolimbal allograft (KLAL, n=19 eyes, 0.1%). Regarding the shift in surgical techniques, a significant increase was observed in DSAEK (P<0.001), whereas PKP was significantly decreased (P=0.005) over the 8?year period. No significant change was seen in the rates of DALK (P=0.354), tectonic graft (P>0.999) and KLAL (P=0.151).
Conclusion: KCN was the most common indication and PKP was the most prevalent technique used for corneal transplantation. Significant changes in surgical techniques were observed over the past 8 years, DSAEK demonstrated an increasing trend while PKP showed a decrease.
