Several intraocular lens (IOL) materials and types are currently available. Polymethyl methacrylate IOLs used to be the gold standard, but the inability of folding limits their use to selected countries and patients. Silicone IOLs were used more in the past because they are less suitable for microincisions. Foldable hydrophobic acrylic is the most popular material, which is also available in ye...

purpose: to assess the optical effect of the technis-z9000 iol decentration by lio-brennan mathematic-optical eye model. methods: the phantom with real eye parameters (lio-brennas) was used for iol technis-z9000 modeling with zemax code. modulation transfer function (mtf) and mtf contrast that represent the ratio of the image data to total object data in optical system were used for analysis. r...

Objective: To assess awareness, knowledge and perceptions of antenatal care-seeking women about cervical ripening (CR) and induction of labor (IOL), and their attitude towards these interventions. Methods: An observational descriptive cross-sectional study which was conducted at an Egyptian teaching hospital. A questionnaire-based interview covered items on women’s demographic and clinical data...

PURPOSE Standard evaluation of aberrations from wavefront slope measurements in patients implanted with a rotationally asymmetric multifocal intraocular lens (IOL), the Lentis Mplus (Oculentis GmbH, Berlin, Germany), results in large magnitude primary vertical coma, which is attributed to the intrinsic IOL design. The new proposed method analyzes aberrometry data, allowing disentangling the IOL...

AIM To compare characteristics of preloaded and non-preloaded intraocular lens (IOL) delivery systems during IOL delivery procedures. METHODS Total 101 human eyes were included in this prospective observational case series. Delivery characteristics of 5 types of IOLs including iSert250 NC60 (NC60), EnVista MX60 (MX60), AcrySof IQ SN60WF (SN60WF), TECNIS ZCB00 (ZCB00), and TECNIS PCB00 (PCB00)...

BACKGROUND Induction of labor (IOL) is a common practice in many parts of the world. However, the benefits and risks of preventive IOL for the mother and baby have yet to be critically assessed. This study is to investigate the effects of preventive IOL for non-urgent indications at term on maternal and neonatal outcomes. METHODS In this study, we applied a propensity score model to mimic a r...

Background The purpose of this prospective, randomised study was to interocularly compare the visual performance after implantation of two different toric IOLs with different haptic design. Methods 59 subjects with corneal astigmatism greater than 1.25 diopter (D) were implanted with an AT TORBI 709M IOL (Carl Zeiss Meditec AG) in one eye and with a Tecnis toric aspheric IOL (Abbot Medical Op...

BACKGROUND/AIM Acrylic lens size and shape may influence the rate of posterior capsule opacification (PCO) and need for Nd:YAG capsulotomy. The aim of this study is to compare the Nd:YAG capsulotomy rate of the three piece acrylic/PMMA AcrySof MA series lens with the one piece acrylic AcrySof SA series lens. METHODS 434 eyes of 329 patients who had cataract extraction and implantation of one ...

Purpose. To analyze the patients with secondary dislocation of CTR and IOL within 5 years from cataract surgery, to determine predisposing factors. Methods. 16 eyes of 15 patients aged 66.2 ± 6.7 (from 49 to 82) with CTR/IOL complex dislocation within 5 years from cataract surgery were compared with 26 patients aged 67.1 ± 7.2 (from 53 to 85), implanted with CTR during cataract surgery to manag...

AIM: To evaluate the postoperative intraocular lens (IOL) rotational stability and residual refractive astigmatism following combined 25-gauge vitrectomy cataract surgery with implantation of a plate haptic toric IOL. METHODS: In this retrospective case series, 32 eyes patients underwent phacoemulsification for vitreoretinal diseases regular corneal at least 1 diopter (D). A IOL (AT Torbi 709M,...
