PURPOSE To evaluate the effect of ethylenediaminetetraacetic acid (EDTA) on posterior capsular opacification (PCO) of rabbits and to assess its effect on intraocular tissues. METHODS Modulation of matrix metalloproteinase (MMP) activity in the aqueous following cataract surgery in rabbits and its prevention by different doses of EDTA was determined by zymography. For evaluation of PCO, lensec...

BACKGROUND/AIMS To investigate the incidence of Nd:YAG-laser treatment for posterior capsular opacification (PCO) over a period of 5 years from phacoemulsification in an unselected population, comparing outcomes for three acrylic intraocular lenses (IOLs). METHODS Retrospective longitudinal cohort study comprising 900 eyes. Three subgroups of 300 eyes, receiving the AR40, AR40e (Abbott Medica...

PURPOSE This meta-analysis aims to evaluate the differences in performance of posterior capsular opacification (PCO) between hydrophobic acrylic intraocular lens (IOLs) and hydrophilic acrylic IOLs. SETTING Tianjin Medical University, Tianjin Eye Hospital, Tianjin Key Laboratory of Ophthalmology and Visual Science, Tianjin, China. DESIGN Systematic review of randomized controlled trials (RC...

This study analyzes the results of cataract surgery with primary intraocular lens implantation in unilateral childhood traumatic cataract following penetrating trauma and its long term follow up. It is a hospital based study of 114 children (age 3-10 years) with unilateral traumatic cataract who underwent extracapsular cataract extraction/ lens aspiration with implantation of posterior chamber ...

The lens of the eye is a flattened transparent globe, through which light must pass on its way to the retina. It consists of only two cell types, elongated fiber cells covered anteriorly by a monolayer of epithelial cells. Cataract, or loss of lens transparency, accounts for about 42 percent of all blindness. Globally, more than 20 million people now have cataract, a number that may double by 2...

S ince their clinical introduction 10 years ago, hydrophobic acrylic IOLs have gone on to become the most popular foldable IOL category worldwide. According to the annual Leaming surveys of the American Society of Cataract and Refractive Surgery membership, hydrophobic acrylic has been the most preferred IOL material since 1998, and was favoured by 63% of respondents in the 2002 poll. This sust...

I mprovements in techniques, instrumentation, and intraocular lens design appear to have been associated with declining rates of posterior capsule opacification following cataract surgery. While morbidity associated with posterior capsule opacification and its treatment, Nd:YAG laser capsulotomy, is limited, progressive opacification affects quality of vision and visual function, while capsulot...

Purpose: To assess the preclinical safety and performance of a new precision pulse capsulotomy (PPC) method. Design: Human cadaver eye studies and surgical, slit-lamp, and histopathologic evaluation in a consecutive series of 20 live rabbits. Participants: Human cadaver eyes and New Zealand white rabbits. Methods: Precision pulse capsulotomy uses a highly focused, fast, multipulse, low-energy d...
