Filter by:Myopia has become a global public health issue. Myopia affects the psychological health of children and adolescents and poses a financial burden. Therefore, early detection and prediction of children at a high risk of myopia development and progression are critical for precise and effective interventions. In this study, we developed a deep learning system DeepMyopia, based on fundus images with the following objectives: 1) to predict myopia onset and progression; 2) To detect myopic macular degeneration for AI-assisted diagnosis; 3) To predict the development of myopic macular degeneration; 4) evaluate its cost-effectiveness.
The purpose of the study is to use the polarization sensitive optical coherence tomography (PS-OCT) developed by Singapore Eye Research Institute, to evaluate the potential OCT scleral biomarkers capable of predicting risk of myopia progression.
The goal of this study is to compare the performance of two daily disposable silicone hydrogel contact lenses.
The purpose of this study is to assess long term performance and safety of AONDA in a real world setting when worn as daily wear or continuous wear for vision correction. This study will be used to support AONDA's marketability in Europe and other locations.
The purpose of this study is to investigate the effect of ceasing treatment with dual focus soft contact lenses.
The study objective was to gather short-term clinical performance data for two soft contact lenses.
The clinical investigation objective is to evaluate safety and performance outcomes of trifocal IOL implantation to improve vision in patients with cataract and/or ametropia (hyperopia, myopia) and/or presbyopia. Retrospective data from preoperative status up to 12 month postoperative status will be collected from patients that were implanted with Medicontur's 640PM intraocular lens: - Preoperative status: Preoperative Screening and Baseline - Surgery: IOL implantation - M1: 1 month +/- 2 weeks postoperative follow-up - M3: 3 months +/- 1 month postoperative follow-up - M12: 12 months +/- 3 months postoperative follow-up
The goal of this interventional comparative study is to assess the efficacy and safety of a novel regimen of preservative-free unit-dose topical anesthetics for controlling early postoperative pain following single-step transepithelial PRK surgery. The main research questions to answer are: - Question 1: Are topical anesthetics effective in reducing post-PRK pain? - Question 2: Are short-term topical anesthetics toxic to the cornea? - Question 3: How to prevent abuse of topical anesthetics by patients at home? Participants were planned to undergo a bilateral single-step transepithelial PRK surgery to correct their refractive errors and received a standard post-PRK treatment regimen for both eyes. Additionally, one eye was offered a preservative-free topical anesthetic as an experimental group and the other eye was offered a preservative-free artificial tear as a control group.
To evaluate and to compare the effect of orthokeratology (OK) on axial elongation in French myopic children.
A prospective, self-control, double-blind design was conducted in Tianjin. Two hundred participants were assigned to wear two kinds of spectacle glasses. To examine the effect of free-toroidal design and aspherical lens on the subjective visual quality among the myopic population.
