PURPOSE To measure in vivo and objectively the monochromatic aberrations at different wavelengths, and the chromatic difference of focus between green and infrared wavelengths in eyes implanted with two models of intraocular lenses (IOL). METHODS EIGHTEEN EYES PARTICIPATED IN THIS STUDY: nine implanted with Tecnis ZB99 1-Piece acrylic IOL and nine implanted with AcrySof SN60WF IOL. A custom-d...

purpose : the aim of this study was to investigate the effect of misalignment (tilt & decentration) of iols in cataract surgery using liu-brennan optical eye model in a simulation. methods : a phantom with the real eye parameters –liu-brennan model– and tecnis z9000 iol were used for simulation. results : results showed that with 0.4 mm decentration and more the modulation transfer function (mt...

purpose : to evaluate the outcome of iris-claw phakic intraocular lens (piol) implantation for high myopia in a subspecialty training setting methods : iris-claw phakic artisan (ophtec b.v., groningen , the netherlands) intraocular lens implanted patients were invited for an evaluation visit: 83 eyes had been operated on by a group of 10 cornea fellows under the supervision of nine anterior seg...

presbyopia is a major refractive challenge for the coming decades. a variety of surgical procedures like scleral expansion, zonal photorefractive keratectomy, and corneal inlay implantation have been investigated none have yet gained popular acceptance. implantation of intraocular lenses (iols) at the time of cataract surgery or refractive lens exchange provides another opportunity to tackle th...
