Analysis of causes and outcomes of corneal transplantation in al-zahra eye hospital in southeast of Iran from 2011-2016

Background: Corneal transplantation is known as the most successful and common type of organ transplant, but it calls for more intensive and long-term care. Given the lack of adequate information on this important surgery in this province and the differences between indications and causes of corneal transplantation, the present research was carried out to examine the causes and outcomes of corneal transplant in patients visiting Al-Zahra eye hospital who had received donated cornea in the past five years.Methods: In a retrospective analytical-descriptive study 135 files of 149 eyes that had gone through corneal transplantation were examined. Information on the age, gender, residence, indications, and surgery consequences was extracted and was analyzed in SPSS 19 statistical software with descriptive statistics (percentage, frequency, mean, and standard deviation.Results: The highest transplant indication was keratoconus with a frequency of 39.9% followed by bullous keratopathy, corneal opacity, and transplant rejection with frequencies of 16.1, 12.7, and 10.1%, respectively. Other indications were corneal scar (9.4%), corneal perforation (2.7%), trauma (2.7%), and Fuchs’ corneal dystrophy (1.3%) in the order mentioned. Concerning postoperative complications in this research, 57.7% of the eyes (86 cases) showed no complication. Moreover, complications were mostly related to astigmatism with a frequency of 30.8% (46 cases).Conclusions: In general, the most common indication in this research was keratoconus. Most surgeries were also complication-free and most complications were associated with astigmatism
