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 ...

purpose: to evaluate the efficacy and safety of the artisan phakic intraocular lens (piol) for the correction of high myopia. methods: in this prospective study of 22 eyes of 14 patients with high myopia, artisan piols (ophtec bv) were implanted. uncorrected visual acuity (ucva), best corrected visual acuity (bcva), refraction, astigmatism, safety, and predictability were analyzed. results: the...

PURPOSE To compare experimental optical performance in eyes implanted with spherical and aspheric intraocular lenses (IOLs). METHODS Corneal, total, and internal aberrations were measured in 19 eyes implanted with spherical (n=9) and aspheric (n=10) IOLs. Corneal aberrations were estimated by virtual ray tracing on corneal elevation maps, and total aberrations were measured using a second-gen...

PURPOSE To evaluate the efficacy and reliability of a microincision intraocular lens (IOL) and its use in biaxial microincision cataract surgery (MICS). SETTING Atatürk Training and Research Hospital, Ankara, Turkey. DESIGN Prospective clinical study. METHODS A microincision IOL (Akreos MI60) was implanted after cataract extraction by the biaxial MICS technique. Over a postoperative follo...

PURPOSE To evaluate visual function after bilateral implantation of a zonal refractive aspheric multifocal intraocular lens (IOL). SETTING Private practice surgery center, Valencia, Spain. DESIGN Cohort study. METHODS Consecutive eyes with cataract had bilateral implantation of Lentis Mplus LS-312 multifocal IOLs. Distance, intermediate, and near visual acuities; contrast sensitivity; def...

PURPOSE To report the results of a new technique for intraocular lens scleral fixation of temporary haptic externalization and four-point fixation for enhanced stability. METHODS Two 10-0 polypropylene strands were fixed at two points 2 mm apart on each haptic of a conventional three-piece intraocular lens, using our previously reported method of temporary haptic externalization after injecto...

The use of intraocular lenses was a great advance in visual recovery after cataract surgery. Although usually with good biocompatibility, some alterations in the intraocular lens material may occur after implantation. Polymethylmethacrylate was the first intraocular lens material to be used on a large scale and assumed to be inert and well-tolerated. We present a rare case of late opacification...

purpose: in the present study we have tried to find the most reliable intraocular lens (iol) power calculation formula in patients with keratoconus (kcn) and cataract. methods: in a prospective case series between october 2010 and march 2012, eligible patients with cataract and kcn underwent phacoemulsification with iol implantation. preoperatively, based on iol master keratometric data iol pow...
