PURPOSE To demonstrate differences in human lens epithelial cell adhesion to different intraocular lens biomaterials in vitro and to determine whether these differences can be influenced by coating the intraocular lens surface with commercially available fibronectin. METHODS A prospective laboratory-based study comparing human lens epithelial cell adhesion to silicone (n=18), polymethylmethac...

A doublet intraocular lens optimized for both chromatic and monochromatic aberration correction in pseudophakic eyes is presented. Ray-tracing techniques were applied to design the lens in white light within a chromatic eye model. Combinations of two materials, already commonly used in intraocular lenses, as acrylic and silicone, were used. Iterative optimization algorithms were employed to cor...

Objective: Evaluate the effectiveness and efficiency of cataract task forces for underprivileged communities, in a follow-up of 4 years, with the use of low price intraocular lens. Methods: Retrospective study, based on a database of a sample of 58 patients randomly selected, submitted to a cataract task force in a rural area of Pernambuco, Brazil. All surgeries were performed by the same surge...

purpose: to report three cases of alport syndrome in one  family with anterior lenticonus and retinal flecks. patients and findings: three members of one family with consanguineous parents are presented who had renal and ocular involvement. they had anterior lenticonus and a beaten bronze appearance in the macula. reduced visual acuity and photophobia were the chief complaints of these patients...

We report a case of a 58-year-old man presenting with a spontaneous and late in-the-bag intraocular lens dislocation to the vitreous. A previous uneventful extracapsular cataract extraction with can-opener style capsulotomy and implantation of a polymethylmethacrylate three-piece lens was performed and, two years after the surgery, the patient developed capsule contraction syndrome with a fibro...

This article compares methods of axial length measurement for determining intraocular lens power and describes bimanual micro incision phacoemulsification for refractive lens exchange and routine cataract surgery, which offers an enormous advantage of maintaining a more stable intraocular environment during lens removal. This advantage may be especially important in high myopes who are at a gre...
