A Prospective, Randomized Clinical Study of Two Phakic Toric Implantable Lenses
Primary Objective: To compare the efficacy and the residual refractive error of EYECRYLTM Phakic toric versus Visian® Toric ICL in moderate to high myopic patient with co-existing astigmatism. Secondary Objectives: To evaluate and compare the safety of EYECRYLTM Phakic toric versus Visian® Toric ICL in moderate to high myopic patients …
3D Visualization System in Highly Myopic Cataract Operation
This study aims to investigate the impact of depth of field differences between the use of the 3D imaging system (NGENUITY® 3D Visualization System, Alcon, TX, USA) and conventional optical microscope in cataract surgery for highly myopic patients on intraoperative parameters and outcomes.
Fundus Effects of Repeated Low-Level Red-Light Therapy in Chinese Myopic Minors: A Randomized Controlled Clinical Trial
Research Objective: The primary objective is to investigate the short-term effects of repetitive low-intensity red light therapy on the fundus of the eyes of underage individuals with myopia. Research Design: This experiment employs a prospective, single-center, randomized, controlled clinical research design. Primary Outcome: Changes in macular sensitivity (microperimetry). Recruitment and …
The Role of Capsular Tension Rings in Intraocular Lens Stability in High Myopia Cataract Patients: A Prospective Self-Controlled Study
Study Purpose: This prospective, self-controlled clinical study aims to evaluate the impact of capsular tension rings (CTR) on intraocular lens (IOL) stability in high myopia patients undergoing bilateral cataract surgery. Each patient will receive CTR implantation in one eye, with the fellow eye serving as control. Postoperative outcomes, including visual …
Effect of IOP Lowering on Progressive HM
Currently, whether and when intraocular pressure (IOP) lowering medication should be used in progressive high myopia (HM) to control axial elongation is still a dilemma. Randomized trials are required to evaluate whether IOP lowering influences the growth of axial length in progressive HM eyes.
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 …
