Purpose:To compare objective image quality at distant, intermediate, and near foci with the corresponding visual acuity (VA) in patients symmetrically implanted with 5 different diffractive multifo...
Purpose The aim of the study is to evaluate the visual acuity and patient satisfaction at varied distances under photopic and mesopic lighting conditions in patients bilaterally implanted with aspheric diffractive multifocal one-piece intraocular lenses.
This study compares the clinical through-focus visual acuity (VA) in patients implanted with different intraocular lens (IOL) to optical bench testing of the same IOLs to evaluate the suitability of optical metrics of predicting clinical VA. Modulation transfer function and phase transfer function for different spatial frequencies and US Air Force pictures were measured using an optical bench for two monofocal IOLs, three multifocal IOLs and an extended range of vision IOL. Four preclinical metr...
Purpose To evaluate the clinical outcomes after cataract surgery with implantation of a new diffractive multifocal intraocular lens (IOL) with a lower near addition (+2.75 D.). Methods 143 eyes of 85 patients aged between 40 years and 83 years that underwent cataract surgery with implantation of the multifocal IOL (MIOL) Tecnis ZKB00 (Abbott Medical Optics,Santa Ana, California, USA) were evaluated. Changes in uncorrected (uncorrected distance visual acuity, uncorrected intermediate visual acuit...
Abstract To investigate the correlations existing between a trifocal intraocular lens (IOL) and a varifocal IOL using the "ex vivo" optical bench through-focus image quality analysis and the clinical visual performance in real patients by study of the defocus curves. This prospective, consecutive, nonrandomized, comparative study included a total of 64 eyes of 42 patients. Three groups of eyes were differentiated according to the IOL implanted: 22 eyes implanted with the varifocal Lentis Mplus L...

Hintergrund Die Wahl der passenden Kunstlinse und deren Berechnung stellt eine der grosten Herausforderungen in der modernen Kataraktchirurgie zur Bestimmung der postoperativen Refraktion dar. Diese klinische Studie vergleicht die Genauigkeit der Berechnungen zweier lasergestutzter optischer Biometriegerate, IOL-Master 500 (Carl Zeiss Meditec AG, Jena, Deutschland) und Lenstar LS900 (Haag-Streit AG, Bern, Schweiz), ohne postoperative Ergebnisse zu berucksichtigen.
PURPOSE: To describe femtosecond laser cataract surgery and discuss the published peer-reviewed articles to have a fair evaluation of this new technology and its comparisons to conventional phacoemulsification surgery. METHODS: The technology information released in this article comes from the key individuals in each of the U.S. Food and Drug Administration-approved companies and from the available commercial information. Bibliographic research was performed in PubMed and MEDLINE for the publish...

Purpose To evaluate refractive and visual parameters related to distance, intermediate, and near vision after cataract surgery and the optical quality of a new diffractive trifocal intraocular lens (IOL). Setting Vissum Instituto Oftalmologico de Alicante, Alicante, Spain. Design Case series. Methods Patients had bilateral refractive lens exchange and multifocal diffractive IOL (AT Lisa tri 839 MP) implantation. A complete ophthalmology examination was performed preoperatively and postoperativel...
Aim: To evaluate the performance of an aspheric diffractive multifocal acrylic intraocular lens (IOL), ZMB00 1-Piece Tecnis. Setting: Five sites across Europe. Methods: Fifty-two patients with cataracts (average age 68.5±10.5 years, 35 female) were bilaterally implanted with the aspheric diffractive multifocal IOL after completing a questionnaire regarding their optical visual symptoms, use of visual correction and their visual satisfaction. The questionnaire was completed again 4-6 months after...
Purpose To compare the visual performance of multifocal intraocular lenses (IOLs) and monofocal IOLs made of the same material. Methods The subjects included patients implanted with either Tecnis® monofocal IOLs (ZA9003 or ZCB00) or Tecnis® multifocal IOLs (ZMA00 or ZMB00) bilaterally. We conducted a retrospective study comparing the two types of IOLs. The multifocal group included 46 patients who were implanted with Tecnis® multifocal IOLs bilaterally. The monofocal group was an age- and sex-ma...
PURPOSE: To evaluate the performance of two intraocular lenses (IOLs). The new monofocal IOL using a higher-order aspheric optic (Tecnis Eyhance ICB00) was compared to a standard monofocal IOL (Tecnis monofocal ZCB00) of the identical platform and material. METHODS: The medical records of the patients who had undergone cataract surgery with implantation of either the ZCB00 or the ICB00 in the dominant eye from March 2020 to August 2020 and with available data from the 3-month visit were reviewed...
PURPOSE To evaluate the clinical outcomes including patient-reported outcome measures in a sample of eyes undergoing bilateral cataract surgery with implantation of a new model of presbyopia-correcting intraocular lens (IOL). METHODS This non-randomized prospective case series enrolled 206 eyes of 103 patients undergoing phacoemulsification cataract surgery with bilateral implantation of the TECNIS Synergy IOL (Johnson & Johnson Vision). High and low contrast visual acuity, refractive, defocus c...
PURPOSE To objectively analyze the optical quality of the FineVision Toric intraocular lens (IOL) with two cylinder powers when different combinations of rotations and residual refractive errors are induced. METHODS This study assessed the FineVision Toric IOL with two different cylinder powers: 1.5 and 3.0 diopters (D). Three different rotation positions were considered: centered, 5° and 10° rotated. An optical bench (PMTF) was used for optical analysis. The optical quality of the IOLs was calc...

The TECNIS Eyhance IOL(Model ICB00) was compared with a standard monofocal IOL (TECNIS monofocal, Model ZCB00). Setting European multicenter study. Design Prospective, bilateral, randomized, comparative/evaluator-masked, controlled study. Methods Adult subjects scheduled to undergo bilateral, primary phacoemulsification cataract extraction and posterior IOL implantation were randomized to receive ...
Purpose To test the performance of a new monofocal intraocular lens, intended to extend depth of focus (Tecnis Eyhance, ICB00; Johnson & Johnson Vision, Inc) (ICB-IOL), in comparison to a standard monofocal IOL (Tecnis 1-piece, ZCB00; Johnson & Johnson Vision, Inc) (ZCB-IOL) of the same platform and material. Methods Assessment of the optical performance of the two IOLs was made in vitro using an optical test bench with a model eye. The spherical aberration, modulation transfer function (MTF), a...
In this article, we review the latest research related to presbyopia management at the time of cataract surgery with attention focused on available options in the USA. With refractive cataract surgery, patient satisfaction is largely dependent on preoperative expectations with regard to spectacle independence and photic phenomena. Monovision with monofocal intraocular lenses have the highest rates of spectacle dependence but the lowest rate of photic phenomena. Extended depth of focus lenses pro...

Purpose Multifocal intraocular lenses (MIOLs) are often discouraged in patients with or at risk of retinal disorders (including diabetic retinopathy, age-related macular degeneration, and epiretinal membranes), as MIOLs are believed to reduce contrast sensitivity (CS). Concerns with MIOLs have also been raised in individuals with visual field defects, fixation instability or eccentric preferred retinal locations. The aim of this study is to review the influence of MIOL on quality of vision in pa...
