The lens is a highly organised, transparent structure that has evolved to alter the refractive index of light entering the eyes. With the practice of cataract extraction surgery and intraocular lens (IOL) implantation good unaided distance visual acuity is now a realistic expectation post-surgery. Monovision does not allow full advantages of binocularity, including stereopsis at near. Multifoca...

Diffractive multifocal intraocular lenses (IOLs) modulate chromatic aberration and reduce it at certain distances due to interactions between the refractive diffractive components. However, extent which computer modeling on bench measurements of IOL translate in patients implanted with these IOLs (MIOLs) is not yet fully understood. In this study, we compare difference focus longitudinal aberra...

PURPOSE To evaluate the visual performance of different types of intraocular lens (IOL) in eyes submitted to femtosecond laser (FSL) cataract surgery and to analyze whether this technology could result in spectacles independence. DESIGN Retrospective comparative case series. METHODS Consecutive eyes that were scheduled for FSL cataract surgery were included in this study. After one month po...

AIM To assess the accommodative power of a new foldable monofocal intraocular lens. METHOD A prospective randomised non-masked clinical interventional study. The study included 40 patients attending the hospital for cataract surgery and who were randomly distributed into a study group receiving a new foldable monofocal intraocular lens with flexible haptics, and a control group receiving a st...

PURPOSE The visual performance of pseudophakic eyes depends on the type of intraocular lenses (IOLs) that are implanted. Aspherical and multifocal IOLs have recently been developed to improve visual quality after cataract surgery, but multifocal IOLs can be associated with decreased contrast sensitivity (CS), halos, and glare. This study compares the visual performance of monofocal and multifoc...

AIM To evaluate the visual function after bilateral implantation of aspheric diffractive multifocal Tecnis ZMA00, aspheric monofocal ZA9003 versus spherical monofocal Akreos Adapt intraocular lenses (IOLs). METHODS Tecnis ZMA00, Tecnis ZA9003 or Akreos Adapt IOLs were bilaterally implanted in 180 eyes from 90 patients. The following parameters were assessed 3 months postoperatively: monocular...
