Filter by:The prevalence of myopia is seemingly increasing, and it is one of the major causes of blindness. High myopia is defined as a refractive error with spherical equivalent exceeding -6 diopters and/or the axial length longer than 26.5 mm. The global prevalence of high myopia is estimated to rise from 2.7% of the world population in 2010 to 9.8% of the world population in 2050. High myopia is characterized by axial length elongation, and consequent stretching of the posterior eye wall (thin retina and choroid). There are many complications of high myopia such as posterior staphyloma, lacquer cracks and myopic choroidal neovascularization. Normal labour may cause the ocular complication in pregnant women with high myopia, such as macular hemorrhage. Therefore, the caesarean section with epidural anesthesia is recommended. Moreover, there is no standard screening guideline for pregnant women with high 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 purpose of this study is to report the changes in accommodation, aberrations, and myopia in patients wearing multifocal soft contact lens for various durations. The study objectives are to: 1. Determine the effects of wearing multifocal soft contact lens on accommodation and aberrations over a 12-month period. 2. Determine the effect of wearing multifocal soft contact lens on myopia over a 12-month period.
Corneal asphericity is expressed numerically as the "Q-value". A minus value means that corneal curvature flattens towards the periphery and the cornea is prolate in shape, but when the curvature steepens towards the periphery, the cornea is oblate in shape and has a positive Q-value. The current study evaluates the effect of LASIK eye surgery on corneal asphericity by comparing 2 software treatment platforms; the Q value customized ablation versus the conventional Wave-front optimized ablation in a fellow eye study pattern.
The purpose of this multicenter randomized clinical trial is to evaluate the adjunctive effect of repeated low-level red-light therapy (RLRL) and orthokeratology (ortho-k) on myopia control in ortho-k non-responders who have undergone ortho-k treatment but were still experiencing fast myopia progression.
Successful treatment of residual refraction 6 months after IOL Implantation with Relex-Smile.
The objective of the study is to measure the difference in the lag of accommodation between DOT spectacle lenses and control spectacles.
Objective: to evaluate the efficacy of different concentrations of atropine eye drops in controlling the progression (diopter, axial length) of high myopia in young children, and to compare the compliance, adverse reaction and regression rate of different concentrations of atropine eye drops in myopia control. Intervention: Group 1 (0.01% atropine group), Group 2 (0.04% atropine group), Group 3 (0.1% atropine group). During the 2-year intervention period after entering the group, each concentration of atropine eye drops were given every night at a fixed time before going to bed, one drop each time, implemented by parents (supervision), and the wechat small program was completed.
The aim of this study is to assess visual and refractive outcomes after laser vision correction (LVC) - ReLex Smile to correct residual myopic refraction after 6 months of pseudophakic (IOL) implantation. 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.
The objective of this study is to determine whether the remote monitoring of myopia patients with the EyeQue Insight (visual acuity test) can replace regularly scheduled follow-up visits.
