We hypothesize that an intraocular lens (IOL) with higher-order aspheric surfaces customized for an individual eye provides improved retinal image quality, despite the misalignments that accompany cataract surgery. To test this hypothesis, ray-tracing eye models were used to investigate 10 designs of mono-focal single lens IOLs with rotationally symmetric spherical, aspheric, and customized sur...

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 evaluate blue-light attenuation in eyes with a tinted intraocular lens (IOL) or an untinted IOL. SETTING Department of Ophthalmology, University Hospital of Crete, Crete, Greece. DESIGN Comparative case series. METHODS Patients had lens extraction and implantation of an Acrysof Natural tinted or Tecnis ZA9003 or Softec III untinted acrylic IOL. The luminance ratio of green (530...

PURPOSE To compare the rotational stability and posterior capsule opacification (PCO) rate in eyes with a 1-piece or 3-piece acrylic intraocular lens (IOL). SETTING Department of Ophthalmology, Medical University of Vienna, Vienna, Austria. DESIGN Prospective randomized masked clinical trial. METHODS Patients with age-related cataract received a plate-haptic acrylic IOL (Acri.Smart 46S) i...

PURPOSE To determine the efficacy, stability, and predictability of refractive surgery for hyperopia using four different procedures: photorefractive keratectomy (PRK), laser in situ keratomileusis (LASIK), implantation of a phakic intraocular lens (PIOL), and removing the transparent lens with IOL implantation. METHODS We operated on 184 eyes with hyperopia; 56 eyes had less than +2.00 D (lo...

Phakic intraocular lens (IOL) implantation is an increasingly popular option in surgical correction of refractive error. To date, reports of long-term morbidity are infrequent in the literature. We encountered 3 patients who experienced corneal decompensation and cataract progression following angle-fixated anterior chamber phakic IOL placement.

One of the most common cause decrease vision in a pseudophakic patient is formation posterior capsular opacification (PCO) which affected by several factors like design implanted intraocular lens (IOL) and material IOL. PCO incidence has been reported to be 20.7% at 2 years & 28.5% 5 years. Decrease because necessitates capsulotomy with neodymium yttrium aluminum garnet (Nd-YAG) laser create sm...

IMPORTANCE The efficacy and safety of primary intraocular lens (IOL) implantation during early infancy is unknown. OBJECTIVE To compare the visual outcomes of patients optically corrected with contact lenses vs IOLs following unilateral cataract surgery during early infancy. DESIGN, SETTING, AND PARTICIPANTS The Infant Aphakia Treatment Study is a randomized clinical trial with 5 years of f...

BACKGROUND With increasing availability of toric intraocular lenses (IOL) for cataract surgery, real-world refractive outcome data is needed to aid the counselling of patients regarding lens choice. We aim to assess the outcomes of toric intraocular lens use in the non-specialist environment of a typical United Kingdom NHS cataract service. METHODS A retrospective cohort study conducted at th...
