Frequency and Causes of Different Corneal Transplantation Surgeries in Patients Referred to the Ophthalmology Department of Imam Khomeini Hospital in Ahvaz, Iran

Corneal transplantation is one of the most common eye surgeries and the most common and successful tissue transplant in the world. The aim of this study was to determine the frequency of causes and types of corneal transplantation in patients referred to the ophthalmology ward of Imam Khomeini Hospital in Ahvaz from 2003 to 2018.

This descriptive study was performed on the records of the patients who underwent corneal transplantation. The information included age, sex, cause of transplantation, sex and age of the donor, need for re-transplantation, reason for re-transplantation, laterality of cornea and the type of operation.

The mean age of patients receiving cornea was 50.93 years and included 491 (49.3%) male and 505 (50.7%) female. 51.7% of corneal transplant operations were related to the right eye and 47.9% of the operations were related to the left eye respectively. PBK was the most cause of corneal transplantation. Most patients underwent corneal transplantation by PK and then DSAEK.

Frequency of PBK was increased in this study as compare to other previous studies which may be due to significant increase in the rate of phacoemulsification surgeries. DSEAK and DMEAK have become more accepted and favorable surgeries in the case of corneal endothelial disease. Based on new surgical techniques and advances in post of management we suggest, new meta-analysis study to evaluate associated diseases , comparison of the regraft rate in different surgical techniques and post op management of them.
