28 Clinical Trials for Myopia
The goal of this clinical trial is to evaluate the safety and efficacy of the DG1 spectacle lens for myopia progression control in children. * To assess if the DG1 lens will slow the progression of myopia through an adjusted mean difference (e.g., age and baseline SER) of approximately 0.75D in cycloplegic spherical equivalent autorefraction refractive error compared to single-vision (SV) spectacles over the study period. * To assess if DG1 lens will slow the progression of myopia through an adjusted mean difference (e.g., age and baseline SER) of approximately 0.3mm in axial elongation compared to SV over the study period. The clinical trial will compare DG1 spectacle lens to single vision spectacle lens. Participants will wear spectacle lenses and return for visits at regularly scheduled intervals through a 36-month follow up visit. All subjects who complete the 36-month visit will continue in the study for an additional 12 months for the rebound evaluation.
The goal of this clinical trial is to learn if daily brief periods of specialized soft contact lens wear work to slow the progression of nearsightedness in children. Additionally, the study will learn about the compliance and safety of specialized soft contact lens wear in children. The main questions it aims to answer are: Does wearing specialized soft contact lenses daily slow myopia progression and axial elongation? What visual/ocular problems do participants have when wearing specialized soft contact lenses? Researchers will compare two soft contact lenses to see if specialized soft contact lens wear works to treat childhood myopia progression. Participants will 1. Wear either a single type of soft contact lens or two types of soft contact lenses at alternate times daily full time in both eyes for one year. 2. Visit the clinic at 2 weeks, 1 month, 3 months, 6 months, and 12 months for checkups and tests 3. Keep a diary of the lens-wearing times.
The objective of this study is to explore the safety and efficacy of SHJ002 Sterile Ophthalmic Solution relative to atropine in myopia control SHJ002 is an antisense oligonucleotide to neutralize a specific microRNA.
The goal of this clinical trial is to study changes in eye shape of nearsighted young adults using low-dose atropine eye drops or soft multifocal contact lenses. The main questions it aims to answer are: * do low-dose atropine and soft multifocal contact lenses affect the shape of the peripheral eye? * are changes in peripheral eye shape from these interventions influenced by changes in the focusing system of the eye? Participants will: * have multiple different types of photos taken * have their prescription for glasses/contacts checked * have their eye health checked, including the use of dilating eye drops * be randomly assigned to use eye drops every night or wear special contact lenses daily instead of their typical contacts * will complete five study visits over the course of 12 months Researchers will compare young adults using low-dose atropine to those wearing soft multifocal contact lenses and to those using no intervention to see if using these interventions affects retinal shape.
Currently, optical and pharmacological interventions have been developed to prevent the progression of childhood myopia. However, no myopia control strategy has been shown to have complete efficacy in controlling myopia progression in children. One possible reason is that risk factors contributing to the development of myopia were not controlled in previous clinical studies including time outdoors and near vision behaviour. This study aims to quantify time spent outdoors and near vision behavior in myopic children and its impact on myopia control efficacy. The outcomes of this study will guide clinicians on risk management and improve responses to existing treatments for progressive myopia.
The study explores the suppression of myopia via violet light.
This is a 3-visit, single site, observational clinical study to evaluate the characterization of the central and peripheral wavefront aberration profiles in pediatric myopic subjects.
This is a conventional efficacy trial to validate the results from previous clinical trials for younger children; the 12-month efficacy results will be used to predict the 3-year treatment efficacy. This is a randomized, controlled (1:1), multisite, subject- and observer-masked, 2-arm parallel group study.
This research project aims to provide additional knowledge of pharmacological and optical methods of myopia control and to gain a better understanding of the biometry of the pediatric eye, which contributes to the onset and progression of myopia. As a result, this study will improving our best practices for myopia control in pediatric patients.
Low-level red-light technology provides a new and innovative myopia control approach. This strategy enables relatively high energies of light to be delivered at much shorter durations of exposure to induce the myopia control effect. The efficacy of the low-level red-light technology has been proven in a Chinese population. This trial demonstrated that 3-minutes per session twice a day repeated low-level red-light treatment controlled 87.7% of refraction progression and 76.8% of axial length elongation when the time of compliance to the treatment was 75%. Repeating this RCT in culturally diverse groups will confirm and translate this technology into a solution for myopia control globally.
This is a multi-center, randomized, double-masked clinical trial. All study devices are market approved/cleared in the localities where the study is conducted. Subjects will be randomly assigned to wear NaturalVue Sphere single vision contact lenses (SVCL) or NaturalVue Multifocal (NVMF) soft contact lenses for a total of three years.
This study is a Single center, single arm, prospective, observational study of clinical outcomes following bilateral cataract surgery and Clareon PanOptix implantation. Subjects will be assessed preoperatively, and at 1 and 3 months postoperatively. Clinical evaluations will include administration of the QUVID and IOLSAT questionnaires, manifest refraction, topography, as well as measurement of visual acuities at distance, intermediate, and near.
This study will be a 12-month, prospective, multicenter, open-label, non-comparative, non-randomized clinical investigation conducted at 8 to 14 sites. A total of 383 subjects will be enrolled to achieve approximately 268 treated subjects, resulting in at least 241 evaluable subjects at the point of refractive stability. After signing the informed consent, subjects meeting all inclusion and exclusion criteria in both eyes may be scheduled for surgery. The follow-up visit schedule will be the same for each operative eye.
The aim of this study is to compare the overall lens satisfaction between two soft multifocal contact lenses.

Corrective eye surgeries, such as Lasik, are widely used to correct focusing problems such as myopia, or nearsightedness. Often these patients develop other conditions like myopic maculopathy or glaucoma which require monitoring with optical coherence tomography (OCT). Since OCT is a light-based test and changes the refractive status of the eye (in the cornea or the lens), it can potentially affect the results of the OCT measurements but has not been sufficiently studied. This pilot study aims at studying the potential change in OCT parameters in the eye after undergoing such surgery.
The purpose of this study is to determine the clinical application of advanced ophthalmic imaging devices such as optical coherence tomography (OCT), retinal function imager (RFI), slit-lamp biomicroscopy (SLB), PERG in diseased eyes and normal controls. There are two phases in this study. The first phase is an observational phase which studies the eye in various conditions. The second phase is an interventional phase which studies the changes in the eyes after taking an over-the-counter medical food (Ocufolin) for 6 months.
The purpose of this study is to measure how the quality of life, the structure of eye, and vision change after treatment for the opacities in the gel (vitreous) that fills the center of eye which cause vision disturbances commonly called "floaters". In this study the vitreous floaters are treated using a Neodymium-doped yttrium-aluminum-garnet (Nd:YAG) laser. The FDA has approved the use of this laser to treat membranes in the eye.
