Comparative evaluation of epidemiological factors and complications of cataract surgery in diabetic patients versus non diabetic patients
Introduction: in attention to prevalence of cataract as one of the most common disease in ophthalmology, also extraction with intraocular lens implantation as the most common surgery in ophthalmic surgery .this study was designed for comparison of epidemiologic factors and rupture of posterior capsule during surgery between diabetic and non diabetic patients.
Methods: the manner of this study was retrospective and information was prepared by extraction from the files of operated patients during of three years in tonekabon teaching hospital and information analyzed by SPSS 11 software.
Results: from 199 patients that had been undergone cataract extraction and I.O.L implantation, 32 patients had diabetes (16/1℅) that 29 patients type 1 and 3 patients type 2 ,and 167 patients were non diabetic .factor of sexuality had not any role for producing of cataract in diabetic patients. Tearing of posterior capsule during surgery was more common in diabetic patients versus non diabetic patients, and on the chi-square exam and Pierson coefficient equal to 0.000, meaningful relation was existed between diabetes and post capsular rupture .there was no meaningful relation between kind of sexuality and post capsular rupture.
Conclusion: due to more chance of post capsular rupture in diabetic patients versus non diabetic patient .its better that cataract surgery in diabetic patients to be done with the best controls and equipments (vitrectomy machine).also prospective study for further evaluation of other complication of cataract surgery in diabetic patients to be proposed
Key words : cataract ,posterior capsule rupture
