Abstract :
Purpose: To report the 27-year statistical data from the Central Eye Bank of Iran (CEBI) and its activity.
Methods: All CEBI records regarding procured eyes, tissue utilizations, corneal
transplants per capita, and indications for keratoplasty from 1991 to 2017 were analyzed.
Results: In total, 115,743 whole eyes were donated during the 27-year period. Out of
the 114,169 eyes donated between 1994 and 2017, 95,314 eyes were distributed for
transplantation, and 95,057 corneas were actually transplanted. The mean annual rate of
corneal transplants per capita was 55.10−6 ± 27.10−6. Although penetrating keratoplasty
(PKP, 70%) was the most common technique of corneal transplantation during the
study period, it exhibited a decreasing trend between 2006 and 2017 (P = 0.048). It
was in contrast to Descemet stripping automated endothelial keratoplasty (DSAEK) that
demonstrated an increasing trend during the same period (P < 0.001). Keratoconus (KCN,
39.70%) was the most leading indication for keratoplasty over the last three decades
followed by bullous keratopathy (BK, 18.5%), corneal scar and opacities (15.7%), and graft
failure (GF, 7.5%), with an increasing trend for BK, GF, and KCN. A majority of scleral
tissues (83.7%) were utilized for orbital implant protection.
Conclusion: An increasing trend in the number of procured eyes was observed over the
past 27 years in Iran. The most leading indications for corneal transplantation were KCN
and BK. While PKP was the most common keratoplasty technique, DSAEK showed an increasing trend over the last 12 years.
