PURPOSE To report non-organic visual loss (NOVL) following cataract surgery with multifocal intraocular lens (IOL) implantation. METHODS After reviewing consecutive cases of NOVL diagnosed by a single neuro-ophthalmologist over a one year period, two patients reported herein attributed their visual symptoms to cataract surgery and multifocal IOL implantation. RESULTS In both patients variab...

purpose : to compare visual outcome of aspheric and spheric intraocular lenses (iols) implantation in patients with age-related cataract in terms of visual acuity (va), contrast sensitivity (cs) and spherical aberration methods : in this prospective randomized interventional study, 59 consecutive cases of senile cataract who had been admitted for cataract surgery to farabi eye hospital, tehran,...

We evaluated the microstructure of the edges of currently available foldable intraocular lenses (IOLs). The methodology used assisted an IOL manufacturer (Hoya, Japan) to optimise the edge profile of its lenses. Ten designs of hydrophobic acrylic, six designs of silicone and 24 designs of hydrophilic acrylic IOLs were imaged under scanning electron microscopy (SEM), and the photographs were imp...

AIM To assess patients' visual performance with glistenings in one piece soft hydrophobic acrylic intraocular lenses (IOLs) (Alcon) 2 years postoperatively. METHODS This cross section trial included 120 eyes with one piece IOL at 2 years postoperatively. Glistening was classified in 4 groups, ranging from 0 (none) to 3 (most evident) according to their severity in IOLs optics observed under a...

PURPOSE To retrospectively evaluate the incidence of neodymium: YAG (ND:YAG) laser capsulotomies for posterior capsule opacification (PCO) seen with hydrophobic and hydrophilic acrylic intraocular lens implants 18 months after surgery. METHODS One hundred and five eyes that had phacoemulsification with a continuous curvilinear capsulorhexis and implantation of either a hydrophobic or a hydrop...

A heterogeneous group of conditions can cause changes to the intraocular lens (IOL) during or after implantation in uneventful cataract surgery. We describe a series of 5 patients presenting distinctive deposits on the surface of hydrophilic intraocular lenses, implanted during routine cataract surgery, with a follow-up of 1 to 24 months. Disposable forceps were found to be the source of the pi...

Intraocular lens (IOL) is an efficient implantable device commonly used for treating cataracts. However, bioadhesion of bacteria or residual lens epithelial cells on the IOL surface after surgery causes postoperative complications, such as endophthalmitis or posterior capsular opacification, and leads to loss of sight again. In the present study, zwitterionic polymer brushes were fabricated on ...

Introduction: The selection of intraocular lens is still debatable in paediatric eye. Due to low cost and fewer intra-operative complication hydrophilic acrylic are implanted volume income countries. There lack comparative study this type with hydrophobic population.
 Aims: To compare the outcomes cataract surgery.
 Methods: Out 48 eyes included study, Group A (n =24) were lens, B len...

purpose: to evaluate the safety, efficacy, stability and predictability of posterior chamber collagen copolymer phakic intraocular lens (piol) implantation to correct myopia and myopic astigmatism in keratoconus-affected patients. methods: uncorrected (ucva) and best-corrected (bcva) distance visual acuity, refraction and complications were evaluated in 22 keratoconic eyes of 14 patients who un...
