To evaluate the efficacy and safety of 650nm low-level red-light irradiation for myopia control and prevention in children under less restrictive conditions than randomized controlled trials. Participants included children(aged 7 to 18 years, spherical equivalent error of 0.5D or below) who are already myopic at recruitment, and those who are of Emmetropia or low hyperopia.
Repeated Red Light Therapy had been used as an amblyopia therapy for children as well as the myopia control in primary schools. However, ultra low lever of red light therapy with irradiance of 0.37mW and 0.60mW effectiveness and safety for 3~ 6 year-old myopia treatment or slow myopia progression are seldom reported.
The goal of this study is to compare the performance of two daily disposable silicone hydrogel lenses.
A multicenter randomized controlled trial, evaluating the efficacy and safety of 650nm low-level red-light irradiation for myopia control and prevention in children. Participants included children(aged 6 to 12 years, spherical equivalent error of 0.5D or below) who are already myopic at recruitment, and those who are of Emmetropia or low hyperopia.
Cordyceps cicadae is a traditional Asian herbal medicine with a variety of bioactive substances and curative effects similar to Cordyceps Cicadae, and it has been reported that anti-dry eye and eye protection ingredients can be extracted. With the advancement of civilization, the number of patients with high myopia is increasing year by year and suffers from complications of dry eye or other eye diseases. In this study, the subjects were provided with cicadae extract or placebo in a double-blind manner, tracked the degree of visual fatigue by regular questionnaires, and measured for visual acuity, axial length and diopter. The purpose of this study is to investigate the effect of cicadae extract on visual acuity and visual fatigue, and to evaluate its potential as a health food ingredient.
Baby Drink is a formula based on lutein, mixed with blueberry fermented liquid, vitamins and minerals. Lutein is an effective antioxidant to prevent retinal damage caused by blue light, but it cannot be produced in the human body and depends on dietary intake. Blueberry fermented liquid is rich in polyphenolic compounds with excellent antioxidant capacity and the potential to reduce oxidative damage to eye cells caused by ultraviolet rays. With the prevalence of 3C products, myopia patients are increasing year by year in various regions, and suffer from eye diseases or vision loss with different degrees of complications. In this study, the subjects were provided with Baby Drink and tracked the degree of visual fatigue by regular questionnaires, and measured for visual acuity, axial length and diopter. The aim of this study is to investigate the protection of Baby Drink on visual acuity and visual fatigue.
Low-lever red light therapy (LLLT) has been used to control myopia progression in China for a few years besides amblyopia therapy for a few decades. This study is to test the efficacy of PBM therapy to myopia children as well as to compare two types of PBM therapy to control myopia progression within one month.
To study the efficacy of myopi control with two methods: low lever red light and peripheral defocus spectacles with four groups and design with prospective, double-blind, randimized, and with control for 6 month.
Study the postoperative visual quality and safety of trifocal intraocular lenses implanted in patients with different levels of myopic maculopathy stages according to Meta-PM staging (stage 0-2).
