Visual Quality Assessment of Posterior Capsule Opacification Using Optical Quality Analysis System (OQAS)
Objective To evaluate intraocular scattering in eyes with posterior capsule opacification by means of an objective scatter index (OSI) obtained from double-pass images of optical quality assessment system (OQAS TM II) and to determine the indication for laser capsulotomy when patients report visual disturbances without decreased visual acuity. Methods In this prospective, observational, and n...
متن کاملSystems of analysis of posterior capsule opacification.
This paper demonstrates the wide variety of systems for the analysis of posterior capsular opacification (PCO). No single system has been proved to be a gold standard and it is difficult to comment on the advantages of one system over another with the limited current knowledge on the effects of PCO on vision. There are few studies that actually compare the different systems of analysis. Researc...
متن کاملPosterior Capsule Opacification: An Overview
DOS Times Vol. 12, No. 4 October, 2006 Posterior capsule opacification (PCO) and posterior chamber intraocular lens (PC IOL) decentration still remain two major complications of successful extracapsular cataract surgery (ECCE) or phacoemulsification. Ridley, who performed the first intraocular lens implantation in 1949, himself noted these complications in his earliest patients.7 In his initial...
متن کاملThe effect of posterior capsule opacification on visual function.
PURPOSE To investigate how posterior capsule opacification (PCO) affects visual function in pseudophakic eyes. METHODS One hundred and six eyes that had undergone uncomplicated phacoemulsification were recruited sequentially. Patients with surgical complications or other ocular disease were excluded. PCO was assessed by a digital retroillumination camera using a software program based on the ...
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 ...
