چکیده
purpose : a review of posterior capsule opacification (pco) after cataract surgery and some affecting factors methods : a cross-sectional study was designed to study cataract patients who underwent cataract surgery between 2003 and 2006 in farabi eye hospital, tehran, iran. random sampling was done. those with a history of uveitis, intraocular surgery, and eye trauma were excluded from the study. the patients were then invited for follow-up visits and study of the results. postsurgical pco percentage was calculated, and its association with variables like sex, age, history of cataract surgery, type of surgery, and type of lens was studied. results : the incidence of pco in patients was 14.2% (11.3 to 17.0 ci=95%) with an incidence of 8.7% and 19.9% in males and females, respectively (p<0.001). pco was not significantly correlated with age. the incidence of pco in those who had undergone cataract surgery at least one year ago was 10.9% while it was 22.7% in those who had received surgery at least 4 years ago (p=0.005). pco incidence in those with and without partial opacity was 31% and 13.2%, respectively (p=0.011). the highest and lowest incidence of pco belonged to those who were operated on with small incision cataract surgery (sics) and phacoemulsification techniques, respectively (p=0.009). the incidence of pco was 24.2% and 12% in cases in whom pmma and foldable lenses were used, respectively (p=0.002). of those with pco after cataract surgery, 31.6% (21.5 to 41.8 ci=95%) needed nd:yag laser capsulotomy. conclusion : in our study, the incidence of pco after cataract surgery was relatively low with a higher incidence in females. preoperative corneal opacity, surgical technique and the lens type can be factors affecting the incidence of pco. iranian journal of ophthalmology 201224(2):3-8 © 2012 by the iranian society of ophthalmology

متن کاملAssessment of Posterior Capsule Opacification after Cataract Surgery
Posterior capsule opacification (PCO) is the most common long-term complication with more than 25% overall incidence within 5 years after cataract surgery of the human eye. The goal of the project described in this paper is to devise a fully automated, objective measure of grades of PCO from so-called retroillumination photographs. We review the current state of the art of existing PCO grading ...
متن کاملCytological factors relating to posterior capsule opacification following cataract surgery.
Simulated extracapsular cataract extractions on cadaver eyes were performed which demonstrated that the cells of the anterior capsule remain largely intact and that only a small amount of cortical lens matter remains postoperatively. Human lens epithelial cells from normal and cataractous lenses were grown in culture. There was no appreciable difference in growth rate between cells from normal ...
متن کاملComparison of hydrophobic and hydrophilic intraocular lens in preventing posterior capsule opacification after cataract surgery
BACKGROUND Posterior capsular opacification (PCO) is a common long-term complication of cataract surgery. Intraocular lens design and material have been implicated in influencing the development of PCO. This study evaluated the association of hydrophobic and hydrophilic intraocular lenses on preventing PCO. METHODS Medline, Cochrane, EMBASE, and Google Scholar databases were searched until Au...
متن کاملObjective quantification of posterior capsule opacification after cataract surgery, with optical coherence tomography.
PURPOSE To evaluate posterior capsule opacification (PCO) in humans after cataract surgery with intraocular lens (IOL) implantation, by using optical coherence tomography (OCT-1). METHODS Sixty-six eyes with PCO and 20 eyes with a normal posterior capsule were analyzed. A 3-mm-long horizontal scan of the posterior capsule was obtained. Measurements at three points and their average were recor...
متن کاملPOSTERIOR CAPSULE OPACIFICATION AND POSTOPERATIVE ENDOPHTHALMITIS FOLLOWING CATARACT SURGERY Predictive and Protective Factors
Modern cataract surgery with implantation of an intraocular lens (IOL) is an increasingly safe and successful procedure, though complications still occur. This thesis addresses the most common complication, posterior capsule opacification (PCO) and the rare but serious complication postoperative endophthalmitis (POE). The pathogenesis of PCO is multifactorial and several surgical and IOL-relate...
