purpose: to compare the effect of implantation of a single-piece hydrophilic foldable acrylic intraocular lens (iol) with rectangular optic edge and a single-piece polymethyl methacrylate (pmma) iol with rounded optic edges on posterior capsular opacification )pco(. methods: this randomized clinical trial study comprised 74 eyes with senile cataract in an otherwise normal eye in patients older ...

Post-operative capsular opacification is a multifactorial physiological consequence of cataract surgery. Opacification involving the central posterior capsule has a significant impact on high and low contrast acuity and low contrast sensitivity. The assessment of Posterior Capsule Opacification (PCO) on cadaver eyes, experimental studies, culture models and in clinical studies has provided an u...

PURPOSE To investigate the relative merit of retroillumination and of reflected light slit-lamp-derived photographs in the assessment of the opacification of the posterior lens capsule. METHODS Retroillumination and slit-lamp-derived reflected-light photographs were taken on 23 consecutive eyes with posterior capsule opacification (PCO) in uncomplicated pseudophakia. Subjective grading was pe...

Posterior capsular opacification (PCO) is the most frequent complication of cataract surgery. Advances in surgical techniques, intraocular lens materials, and designs have reduced the PCO rate, but it is still a significant problem. The only effective treatment for PCO, Nd:YAG laser capsulotomy carries vision-related complications and risks and puts a significant financial burden on the health ...

The most common complication after cataract surgery is postoperative capsular opacification, which includes anterior capsular opacification (ACO) and posterior capsular opacification (PCO). Increased adhesion of lens epithelial cells (LECs) to the intraocular lens material surface promotes ACO formation, whereas proliferation and migration of LECs to the posterior capsule lead to the developmen...

Received for publication January’ 2009 ... ........................... Purpose. The objective of this study is to compare the frequency of Neodymium YAG laser capsulotomy in eyes receiving silicon foldable posterior chamber intraocular lenses with those receiving acrylic foldable posterior chamber intraocular lenses. Material and Methods. This Comparative study was carried out at Ophthalmology ...

PURPOSE To establish an optical section-assisted in vivo rabbit model for capsular bend and posterior capsule opacification (PCO) investigation. METHODS A total of 10 rabbits underwent phacoemulsification surgery and intraocular lens (IOL) implantation. On the basis of the relationship between the anterior capsule and IOL, the rabbits were divided into complete overlap and incomplete overlap ...

One of the most common cause decrease vision in a pseudophakic patient is formation posterior capsular opacification (PCO) which affected by several factors like design implanted intraocular lens (IOL) and material IOL. PCO incidence has been reported to be 20.7% at 2 years & 28.5% 5 years. Decrease because necessitates capsulotomy with neodymium yttrium aluminum garnet (Nd-YAG) laser create sm...

PURPOSE We define the ideal anterior capsulotomy through consideration of capsular histology and biomechanics. Desirable qualities include preventing posterior capsular opacification (PCO), maintaining effective lens position (ELP) and optimising capsular strength. METHODS Laboratory study of capsular biomechanics and literature review of histology and published clinical results. RESULTS Pa...
