Filter by:The goal of this interventional study is to compare the efficacy of Atropine 0.05% to Atropine 0.5% treatment against progression of axial length in European children with progressive myopia, and to evaluate the safety, adherence, and reasons for nonresponse. Subjects will use Atropine eye drops for a period of 3 years, followed by a 2 year observational period.
The goal of this clinical trial is to assess efficacy and safety in patients with myopic chorioretinal atrophy. The main question it aims to answer are: • Percentage of changes in the chorioretinal atrophic area Participants will be implanted one sheet of PAL-222 into the subretinal space through pars plana vitrectomy. Researchers will compare non-therapeutic eye to see if the changes is significant different.
This was a single-blind (participant masked), interventional, prospective, direct refit, bilateral wear short-term fitting study.
This is a two-arm parallel group, non-dispensing study. Participants will be existing active CYPRESS Extension (CPRO-1802-002) subjects. Subjects will undergo additional visual performance assessments.
There was a prospective cohort observational study. Forty hyperopic children, 40 myopic children and 120 emmetropia children were randomly selected from grade 1 to grade 3, and were followed up every six months for 3 years. All patients received cycloplegic refraction examination, ocular biological test, binocular visual function test and a questionnaire related to daily eye habits. A multi-level and multi-dimensional data analysis model was constructed to explore the possible factors affecting the occurrence and development of myopia in children.
The present research focused on the effect of the age for the corneal biomechanics of low and moderate myopia patients after wearing orthokeratology (OK lens). According to age, the included cases were divided into 3 groups. Through the analysis of corneal biomechanical parameters, further learn the influence of OK lens on the patient cornea. It would help ophthalmologist and optometrist find out the potential issue and reach a better control result.
This is a single-site, prospective, single-arm, open-label, real-world evidence study with a minimal study duration of 1-year, up to 2-year follow-up to evaluate overall visual acuity.
The objective of the study is to measure the effect of Diffusion Optics Technology (DOT) spectacle lenses on the choroidal thickness and choroidal vascularity index compared to control lenses.
This study evaluates differences in postoperative visual outcomes between patients receiving Topography-Guided LASIK in one eye and Small Incision Lenticule Extraction in the other eye.
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.
