Purpose: To assess the depth of field (DOF) by means of defocus curve analysis applying different visual acuity criteria in patients following cataract surgery and bilateral implantation of a new trifocal diffractive intraocular lens (IOL).
Methods: Fifty eyes of 25 consecutive patients who underwent implantation of the Asqelio™ trifocal IOL (AST Products Inc., USA) were enrolled in this observational prospective study.
To evaluate depth of field (DOF) provided by different presbyopia-correcting intraocular lens (IOL) designs, comparing the results obtained using different criteria for defining the defocus tolerance. A total of 150 eyes undergoing cataract surgery were enrolled and divided into 6 groups depending on the IOL implanted: AT.LISA Tri (Carl Zeiss Meditec), FineVision (PhysIOL), PanOptix (Alcon Laboratories), Tecnis Symfony (Johnson & Johnson Vision), Miniwell (SIFI MedTech) and Tecnis Synergy (Johnson & Johnson Vision).

Setting: Private university hospital (QuironSalud, Madrid, Spain).
Design: Retrospective case series.
Purpose: The purpose of this study is to develop and assess the accuracy of a new intraocular lens (IOL) power calculation method based on machine learning techniques.
Methods: The following data were retrieved for 260 eyes of 260 patients undergoing cataract surgery: preoperative simulated keratometry, mean keratometry of posterior surface, axial length, anterior chamber depth, lens thickness, and white-to-white diameter; model and power of implanted IOL; and subjective refraction at 3 months post surgery. These data were used to train different machine learning models (k-Nearest Neighbor, Artificial Neural Networks, Support Vector Machine, Random Forest, etc).
Purpose: To evaluate the refractive and functional outcomes of the trifocal 1stQ AddOn (Medicontur) supplementary intraocular lenses (IOLs) designed for implantation into the ciliary sulcus.
Patients And Methods: The study included 18 eyes of 11 pseudophakic patients with uncomplicated previous implantation of monofocal capsular bag IOLs. These patients had a desire for spectacle independence.
Purpose: To evaluate different intraocular lens (IOL) designs and to determine whether extended depth of focus (EDOF) lenses provide a higher depth of field (DOF) than the rest considering both subjective and objective measurements.
Methods: A total of 100 eyes undergoing cataract surgery were divided into six groups depending on the IOL implanted: bifocal designs were Tecnis ZMB and ZLB (Abbott Laboratories, Illinois, USA), trifocal designs were Finevision (PhysIOL, Liège, Belgium) and AT LISA Tri (Carl Zeiss Meditec., Jena, Germany) and EDOF designs were Symfony (Abbott Laboratories, Illinois, USA) and MiniWell (SIFI MedTech, Catania, Italy).
Purpose: To evaluate the refractive predictability obtained with an extended range of vision intraocular lens in eyes with previous myopic laser in situ keratomileusis, confirming which intraocular lens power formula provides the most accurate calculation.
Methods: The study enrolled 71 eyes with previous successful myopic laser in situ keratomileusis surgery of 43 patients undergoing cataract surgery with implantation of the extended range of vision intraocular lens TECNIS Symfony (Johnson and Johnson Vision). Intraocular lens power was calculated using all American Society of Cataract and Refractive Surgeons formulas, and their average value was selected for implantation.
Purpose: To evaluate the development of visual acuity, dysphotopsia phenomena, and subjective sensations in patients implanted with the Tecnis(®) ZMB00 (Advanced Medical Optics Inc, Santa Ana, CA) multifocal intraocular lens.
Methods: In a sample of 70 eyes, distance and near visual acuity, with and without correction, contrast sensitivity, and patient satisfaction, were analyzed at 15, 30, and 60 days post-surgery.
Results: Mean uncorrected distance visual acuity (logarithm of minimum angle of resolution) at 15, 30, and 60 days was 0.
Purpose: To evaluate visual performance in relation to time after implantation of the multifocal Tecnis intraocular lens (IOL) in patients with cataract.
Methods: This prospective case series involved 250 eyes of 137 patients with cataract aged 68.5+/-9.
Purpose: To compare the visual quality after implantation of multifocal intraocular lenses (IOLs).
Setting: Departments of Ophthalmology, Hospital Quirón and Hospital Clínico San Carlos, Madrid, Spain.
Methods: In a prospective nonrandomized consecutive trial, patients had bilateral implantation of Acri.
