Filter by:This is a monocenter, randomized, controlled, parallel-group, double-masked clinical trial to evaluate the effectiveness of test lens in slowing myopia progression with respect to axial length elongation at baseline compared to a single vision spectacle lens (control). A total of 80 children will be recruited where 40 subjects will be allocated either to wear test lenses (group 1) or control lenses (group 2) for 1 year through randomization.
Clinical trial to evaluate the safety and effectiveness of two kinds of ring band cylindrical lens in delaying the progression of myopia
Based on the RE-AIM framework, this project intends to integrate the prevention and control measures of myopia and obesity, and establish a set of key suitable technical packages and guarantee systems for the "comorbidity-common-cause-common prevention" of myopia and obesity in children and adolescents. Dong cheng ,Tongzhou and Changping District in total selected 18 intervention schools and 18 control schools to apply the application, integrate the resources of the "family-school-community-medical institution", and establish a comprehensive combination of myopia and obesity in children and adolescents In the prevention and control demonstration area, intervention study was conducted to evaluate the comprehensive intervention effect of myopia and obesity in children and adolescents in the demonstration area, and to promote it through the regional monitoring system in Beijing. This project is the first time to establish a district-level comprehensive prevention and control demonstration area for children and adolescents with myopia and obesity that can be promoted, including key appropriate technology packages and promotion and application strategies. Healthy Beijing 2030" plan laid the foundation.
The study is aimed to observe the short-term clinical performance of MiSight™ multifocal soft contact lens compared with Proclear™ 1day, including objective examination, subjective acceptability of wearers, and doctors' evaluation of the clinical manifestations of lenses.
The purpose of this trial is to investigate the safety and efficacy of MyopiaX - a digital treatment intended to slow the progression of myopia in children and adolescents.
This is an open-label, controlled, multisite, two-arm parallel group clinical trial of 36-month duration to evaluate the continued safety and efficacy of SightGlass Vision Diffusion Optics Technology (DOT) Spectacles in reducing the progression of juvenile myopia.
This is a phase III, randomized, double-masked, placebo-controlled, parallel-group, multicenter safety, tolerability, and efficacy study of atropine sulfate 0.01% (OT-101) as an investigational treatment for myopia in pediatric subjects
The residual hypermetropic refraction on pseudophakic(Trifocal IOL) patients is difficult to treat surgically. In addition, there are not many suitable options to offer such patients presenting with this condition. Two current common surgeries to treat residual hyperopic refraction are refractive lens exchange (RLE) and excimer laser ablation (LASIK or PRK). Laser procedures: Photorefractive keratectomy (PRK); Laser assisted in situ keratomileusis (LASIK); Risks of LASIK include abnormalities of the corneal flap, epithelial ingrowth, corneal ectasia, refractive surprises, irregular astigmatism, decentration, visual aberrations, a loss of BCVA, infectious keratitis, symptoms, and diffuse lamellar keratitis. Refractive lens exchange (RLE); The risks of RLE are similar to those of cataract surgery and include endophthalmitis, a loss of accommodation, vitreous loss with posterior capsular rupture, and retinal detachment. The method used at the EYE Hospital Pristina using fresh lenticule implantation by ReLex-SMILE is safe and effective method, since there is no flap this prevents invasive damage to the anterior surface of the cornea contrary to the LASIK where flap is present posing risk for epithelial ingrowth. Before SMILE,YAG-laser capsulotomy should be performed on all patients, regardless of posterior capsule ossification, in pseudophakic patients with residual refraction. When the YAG-laser is applied after the SMILE,there will be a diopter change.
To assess the improvement in myopia with phototherapeutic intrastromal corneal collagen cross-linking (PiXL) without epithelial debridement (epi-on) in high oxygen environment for low grade myopia. The study compares two 3.5-mm central ring-shaped zone protocols; 10 min illumination time vs 16:40 min illumination time.
This randomized clinical trial study aims to investigate the efficacy of novel SEED's EDOF based mid-lens design in controlling the myopia progression in Indian children with these specific objectives: 1. To investigate the efficacy of SEED's 1-day pure extended depth of focus lenses controlling myopia progression in Indian children through a one-year randomized clinical study. 2. To investigate the role of SEED's 1-day pure extended depth of focus lenses in altering peripheral refraction of the eye to control myopia progression. 3. To determine if there is any specific cohort that shows better efficacy in myopia control with 1-day pure extended depth of focus lenses based on central and peripheral optics (degree of myopia and optical parameters). 4. To investigate the qualitative assessment of comfort and visual experience with the SEED's EDOF contact lenses through the questionnaire method.
