Clinical Study on the Effectiveness of Diverse Segments Defocus Optimization in Spectacle Lenses for Slowing Myopia Progression
Clinical Trial The goal of this clinical trial is to evaluate the effectiveness of two types of Diverse Segments Defocus Optimization (D.S.D.O.) spectacle lenses in slowing myopia progression in children. It will also assess the safety of these lenses. The main questions it aims to answer are: Do D.S.D.O. lenses …
The Impact of Soft Contact Lenses on the Corneal Neuromediators and Optical Quality in High Myopia Prior to SMILE
To investigate the influence of Neuromediators expression in corneal stromal lenticules and corneal injury repair after small incision extraction
A Real-world Study of 650nm Low-intensity Single-wavelength Red Light for Children and Adolescents
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 …
Association of Genetic Variants With Myopia
This study aims to identify genetic factors linked to myopia, including those that influence a person's risk of developing it and how quickly it progresses (like changes in eye length). It will also examine how different treatments-such as low-dose atropine drops, orthokeratology lenses, specialized glasses, and increased outdoor time-interact with …
Evolution of Ocular Growth in Myopic Children: A Prospective Cohort Study
Myopia and high myopia are the leading causes of visual impairment and blindness worldwide. The total number of myopic people globally was estimated to be 2.6 billion in 2020, and it could reach 4.8 billion by 2050 unless preventive interventions are implemented. Strategies to slow the progression of myopia, such …
A Study of Artificial Intelligence Assisted Small Incision Lenticule Extraction (SMILE) for Surgical Design and Influencing Factors
The goal of this observational study is to learn about the difference of refractive outcomes between Artificial Intelligence and experienced surgeon predicting Nomogram assist SMILE surgical design and the influenced factors of refractive outcomes in patients who underwent Small Incision Lenticule Extraction(SMILE) at the Refractive Surgery Center of Tianjin Eye …
Measurement of Antioxidant Activity and Oxidative Stress in Patients Undergoing Ophthalmic Surgery.
This trial hypothesized that novel laser refractive surgery techniques (LASIK, KLEx) or laser-assisted cataract surgery (FLACAS) could suppress postoperative inflammation and improve recovery in patients by reducing oxidative stress generated by the surgical procedure. It is also intended to verify whether the new laser technology is necessary for clinical use …
Clinical Results of Small Incision Lenticule Extraction (SMILE) for the Correction of High Myopia
Small Incision Lenticule Extraction (SMILE) was introduced in 2011 using the VISUMAX femtosecond laser (Carl Zeiss Meditec, Jena, Germany). It is designed for correction of myopia and myopic astigmatism. It involves the creation of a corneal tissue disk called lenticule and its extraction through a minimally invasive incision, utilizing only …
An Evaluation of LASIK, SMILE and PRK Surgery in Physicians
The principle investigator is evaluating self-reported quality of vision and quality of life in physicians undergoing LASIK, SMILE and PRK surgery.
Zhejiang Adolescent Spine and Vision Health Cohort: A Longitudinal Database Analysis
The aim of study: 1. To investigate the prevalence of scoliosis, other spinal deformities, myopia, and visual impairments in adolescents (aged 6-18) in Zhejiang Province. 2.To track 8-year dynamic changes in spinal curvature and analyze associations between scoliosis, vision disorders, and potential risk factors. 3.To deliver scoliosis health education during …
