Filter by:In this non-interventional retrospective and prospective observational study, the long-term evolution of clinical and iconographic characteristics of patients with pathological myopia will be considered Changes of some specific clinical, tomographic and angiographic variables evaluated on the baseline and after a minimum of 5 years follow-up will be studied.
The purpose of this study is to evaluate the performance of DAILIES TOTAL1 daily disposable contact lenses with regards to subjective symptoms (comfort, dryness, vision) in lens wearers who use identify themselves as substantial digital device users (at least eight hours of digital device use per day).
A Study to Evaluate the Safety and Efficacy of the Bausch + Lomb Myopia Control Lens for the Correction of Myopic Ametropia and Slowing the Progression of Myopia in Children
The goal of this clinical trial is to compare pharmacological and non-pharmacological treatment effects on the children with different predicted myopia progression rate measured by modified multifocal electroretinogram. The main questions it aims to answer are: - the effectiveness of using 0.05% atropine and prescribing DIMS lens for myopia control in children with different myopia progression rates - the contribution of L/M cones in juvenile myopia progression and changes of retinal activities under atropine and DIMS treatment. Participants will have baseline and follow-up eye examinations and given either pharmacological treatment with 0.05% atropine or non-pharmacological treatment with DIMS lens for myopia control. Researchers will compare the changes of refractive errors and axial length after different types of interventions and investigate the relations between the parameters of mfERG responses and the thicknesses of retinal layers and choroid.
The research project titled "A Comparative Study on the Clinical Efficacy, Quality of Life, and Cost of Use of Peripheral Defocus Spectacles, Frame Glasses, and Orthokeratology Lenses in Myopic Children and Adolescents" aims to evaluate different non-surgical myopia correction methods in children. It focuses on assessing the impact of peripheral defocus spectacles, frame glasses, and orthokeratology lenses on the quality of life, clinical effectiveness, and costs associated with each method. The study is a prospective cohort study involving 300 children aged 13-17 years with myopia ranging from -1.00D to -6.00D. It aims to compare the psychological, social, and educational aspects of these correction methods, alongside their costs and clinical outcomes over a period of one year.
This study intends to conduct a relatively comprehensive binocular visual function examination and follow-up on two groups of myopic subjects, one receiving autostereoscopic 3D vision training and the other receiving 2D vision training as a control. The aim is to explore the impact of autostereoscopic 3D vision training on the accommodation and convergence functions of myopes. Additionally, synchronized EEG-fNIRS signals will be collected to investigate whether changes in binocular visual function are accompanied by corresponding alterations in brain function.
Previous Studies reported that low concentration atropine eye drops may be effective in increasing the choroidal blood flow and thickness and this slows myopia progression. purpose of the study is to compare changes in axial length, anterior chamber depth, choroidal thickness, central corneal thickness and anterior scleral thickness among myopic children receiving atropine 0.05% or 0.01% and placebo.
This study aims to investigate the impact of depth of field differences between the use of the 3D imaging system (NGENUITY® 3D Visualization System, Alcon, TX, USA) and conventional optical microscope in cataract surgery for highly myopic patients on intraoperative parameters and outcomes.
The goal of this post-market clinical follow up Study is to demonstrate the efficacy, safety, acceptability, and quality of life implications of Essilor® Stellest® spectacle lenses in slowing myopia progression in European children and adolescents. Participants will receive Essilor® Stellest® at inclusion visit and will be asked for a full time wear (>12 hours daily) for 24 months. The primary endpoints are the change in axial length and cycloplegic autorefraction from baseline to 24 months compared to expected change based on axial length and refraction centile positions at baseline.
This study was designed to gather short-term clinical performance data for 2 soft contact lenses.
