RESUMEN
To investigate indications and methods of surgery in corneal transplantation in Labbafinejad medical center from 2007 to 2009. Records of 1083 patients who had undergone corneal transplantation from 2007 to 2009 were reviewed. Age, sex and indication and type of surgery were evaluated. Patients included 709 [65.5%] male and 374 [34.5%] female subjects with mean age of 43.2 +/- 10.2 year [range, 17 days to 33 years] keratoconus [36.7%] was the most common indication followed by cataract extraction with or without IOL insertion [12.8%]; corneal ulcers due to bacterial, fungal and acanthamoba infections [11.7%]; non herpetic scar and opacities [7.4%]; trachoma keratopathy [5.6%]; corneal dystrophy [4.6%] and mustard gas keratopathy [4%]. The most common type of surgery was penetrating keratoplasty [56.2%] followed by deep anterior lamellar keratoplasty [24.5], tectonic grafts [9.4%], lamellar keratoplasty [3.4%], endothelial graft [3.5%] and keratolimbal allograft without penetrating keratoplasty [3.1%]. During this 3 years period, keratoconus was still the most common indication for corneal transplantation but rate of regraft is increasing in comparison with previous reports. Corneal edema following cataract surgery with or without intraocular lens implantation was the second most common indication. Rate of endothelial grafts and keratolimbal alografts have increased since our previous reports
