Posterior capsule opacification

Survey of Ophthalmology, 1992
A complication of extracapsular cataract extraction with or without posterior chamber intraocular lens (PC-IOL) implantation is posterior capsule opacification. This condition is usually secondary to a proliferation and migration of residual lens epithelial cells.

Posterior capsule opacification

Experimental Eye Research, 2009
Posterior Capsule Opacification (PCO) is the most common complication of cataract surgery. At present the only means of treating cataract is by surgical intervention, and this initially restores high visual quality. Unfortunately, PCO develops in a significant proportion of patients to such an extent that a secondary loss of vision occurs.

Posterior Capsule Opacification in Pseudophakic Eyes

Ophthalmology, 1983
Posterior capsule opacification following extracapsular cataract extraction is a manifestation of proliferation of anterior lens epithelium onto the posterior capsule. In addition to Elschnig pearl formation, vision is decreased in two ways. Multiple layers of proliferated epithelium produce a frank opacity.

Posterior capsule opacification and anterior capsule opacification

Current Opinion in Opthalmology, 2001
Posterior capsule opacification (PCO) is still the most frequent complication of cataract surgery. A variety of studies has led to a better understanding of the pathogenesis of PCO, and strategies of molecular biology have produced new therapeutic options, such as immunological techniques or gene therapeutic approaches.

Posterior Capsule Opacification

Archives of Ophthalmology, 1985
Posterior capsule opacification results from migration of lens epithelial cells onto the posterior capsule, where they produce collagen and contract to cause wrinkling of the capsule. We have designed an in vitro model that reproduces the process of opacification.

Posterior capsule opacification

Current Opinion in Ophthalmology, 1991
Posterior capsule opacification is a frequent complication of extracapsular cataract extraction (ECCE). Recent efforts aimed at elucidating the mechanism of capsular opacification include demonstration of in vitro fibroblastic transformation of lens epithelial cells and the observation that ...

Posterior capsule opacification

Current Opinion in Ophthalmology, 2006
This paper assesses the factors that contribute to the formation of an effective capsular bend as a deterrent to posterior capsule opacification. Its goal is to assist the practicing ophthalmologist in separating current understanding of this process from various working models previously proposed.While a square-edge design appreciably improves ...

Posterior capsule opacification

Current Opinion in Ophthalmology, 2000
Posterior capsule opacification (PCO) is the most common complication following primary cataract surgery. Advances in intraocular lens (IOL) designs that have reduced the amount of PCO following surgery have been made. The understanding of how the IOL design effects PCO has also advanced.

Capsulorhexis size and posterior capsule opacification

Journal of Cataract and Refractive Surgery, 1996
Posterior capsule opacification (PCO) after intraocular lens (IOL) implantation has a multifactored pathogenesis. Capsulorhexis and capsular bag implantation of a one-piece, biconvex poly(methyl methacrylate) (PMMA) IOL are likely to reduce the PCO incidence.

Posterior Capsule Opacification

2010
Posterior capsule opacification (PCO), also known as after-cataract and secondary cataract, is the most prevalent complication following cataract surgery. The basis of the condition is a pronounced wound-healing response from residual lens epithelial cells, which colonize the lens posterior capsule, deform the matrix, and form cell aggregates.
