PURPOSE The purpose of this study was to compare the optical performance of diffractive multifocal intraocular lenses (DMIOLs) with visible (VIS) illumination with that of near infrared (NIR) illumination, the latter being used to test pseudophakic eyes in clinical aberrometers and double-pass systems. METHODS Two DMIOLs of different design (Tecnis +2.75 D ZKB00 and AcrySof +2.5 D SV25T0) wer...

introduction: in cases of poor satisfaction with aphakic glasses and intolerant or reluctant to use contact lenses, secondary intraocular lens (iol) implantation provide an alternative aphakic vision correction. this study aimed to evaluate surgical problems.  intraoperative and postoperative complications and visual acuity outcomes of secondary anterior and posterior chamber intraocular lens i...

purpose: to compare aspheric and spherical hydrophilic intraocular lenses (iols) in terms of contrast sensitivity and visual acuity in photopic and mesopic conditions. methods: this triple-blind randomized clinical trial was performed on 40 eyes of 40 patients at al-zahra eye center, zahedan, iran. the eyes were randomized to standard phacoemulsification procedure with spherical (adapt, b&l;) o...

the aim of this study was to report a new cause of cataract, namely snake bite induced cataract in a dog. a 3-year-old male mongrel dog was referred to our clinic for the assessment of cataract in both eyes. the dog was bitten by a snake nearly 4 months ago. a 40 dioptre acrylic lens with 13 mm haptics was implanted into the lens capsule. in the left eye, posterior synechia was detected in the ...

purpose : cataract surgery is the most common ocular surgery worldwide and in modern era of phacoemulsification with posterior chamber intraocular lens (pc iol) implantation, refractive aspects of surgery is as important as the surgery itself. after the iol implantation, the anterior chamber depth (acd) is increased and the iridiocorneal angle is widened. these changes should be considered for ...

A 83-year-old woman underwent phacoemulsification in the left eye, complicated by posterior capsular rupture and dislocation of nuclear fragments vitreous cavity. She was aphakic referred to Clinica Oculistica, Azienda Sanitaria Universitaria Friuli Centrale, Udine, Italy. After 2 days, she pars plana vitrectomy, with removal fragments, secondary intraocular lens (IOL) implantation. The used a ...

purpose : to evaluate distance and near contrast sensitivity (cs) under photopic and mesopic conditions before and after refractive lens exchange (rle) and implantation of the aspheric acrysof restor (sn6ad3 model) intraocular lens (iol) methods : sixty eyes of 30 consecutive patients after rle underwent bilateral implantation with the aspheric acrysof restor iol. the patients sample was divide...
