Comparison of Defocus Incorporated Multiple Segments® (DIMS®) Lenses Alone Versus Monofocal Lenses + Atropine 0.05% Eyedrops on the Evolution of Ocular Axial Length at 2 Years in Myopia Control in Children: Single-centre Prospective Randomised Controlled 1:1 Open-label Non-inferiority Study

Summary: Myopia is the most common refractive disorder in the world. Many strategies have been developed to control myopia in children. Among them, the instillation of low-concentration atropine eyedrops has been proven to be effective in numerous publications. Nevertheless, the spreading of atropine use is limited by: (1) its uneven availability, (2) a proportion of children with no or poor response, (3) ...

Prospective Randomised Controlled Study in 2 Parallel Arms Comparing Corneal Haze, Visual and Refractive Outcomes and Postoperative Pain According to the Mode of De-epithelialisation (Laser Versus Manual Alcohol) During Photorefractive Keratectomy

Summary: surgical correction of ametropia. A number of improvements have been introduced to overcome the side effects and complications such as corneal haze, epithelial irregularities induced by wound healing, pain and delayed visual acuity recovery associated with PRK surgery. During traditional PRK, the corneal epithelium is mechanically debrided before stromal ablation is performed. Alcohol PRK is frequ...

The Initiating Factors of Myopia Among Primary and Secondary School Students in Tianjin

Summary: 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 ...

Binocular Vision Alternations and Functional Magnetic Resonance Imaging Activation After Implantable Collamer Lens Implantation for High Myopia

Summary: Implantable collamer lens (ICL) is one of the most effective operation for high myopia. Due to refractive correction changed, and prism effect of the spectacle removed, in the early stage after ICL implantation, binocular function might be dysfunction, leading to asthenopia, blurred vision, double vision and so on. This study will recruit the high myopia subjects that scheduled for ICL implantatio...

Prevalence and Environmental Factors for Myopia Among Chinese School-aged Children and Adolescent in Tianjin

Summary: The high prevalence of myopia has become a global public health problem. The study amied to investigate the prevalence and progression of myopia associated with social environmental factors in Tianjin, a Chinese megacity in north China.

Clinical Investigation of the CHEETAH SYSTEM FOR THE CORRECTION OF MYOPIC REFRACTIVE ERRORS WITH AND WITHOUT ASTIGMATISM

Summary: This study will be a 3-phase, 12-months, prospective,single arm, multicenter, open-label, non-comparative, clinical investigation conducted at up to 7 sites. Up to 20 subjects will be enrolled in phase I, up to 30 subjects in phase II, and up to 200 subjects in phase 3 to achieve up to 350 treated eyes.

Post-Market Evaluation of the EVO ICL

Summary: The objective of this study is to assess the rate of early intraocular pressure (IOP) increases following implantation of EVO/EVO+ Implantable Collamer Lens (ICL).

A Visual Outcome Comparison of Topography Guided LASIK Versus Small Incision Lenticule Extraction: A Prospective Contralateral Eye Study

Summary: 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.

A Phase III, Randomized, Double-masked, Placebo-controlled, Parallel-group, Multicenter Study of the Safety and Efficacy of OT-101 (Atropine Sulfate 0.01%) in Treating the Progression of Myopia in Pediatric Subjects

Summary: 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

Surgical Outcomes and Intraoperative Parameters Evaluation of 3D Visualization System for Vitreoretinal Diseases in Highly Myopic Eyes

Summary: To investigate the surgical outcomes and intraoperative parameters evaluation of 3D visualization system for vitreoretinal diseases in highly myopic eyes

A Clinical Study of Short-term Clinical Performance of Multifocal Soft Contact Lens

Summary: The study is aimed to observe the short-term clinical performance of MiSight™ multifocal soft contact lens compared with Proclear™ 1day, including objective examination, subjective acceptability of wearers, and doctors' evaluation of the clinical manifestations of lenses.

The Effect of Sun-like Spectrum With Different Spectrum Composition on Retinal Blood Flow in School Students: a Randomized Controlled Trial

Summary: In 2020, the overall myopia rate among children and adolescents was 52.7% in China. The COVID-19 pandemic has increased students' time of indoor eye-using, and it showed that the light exposure intensity of myopic students is lower than that of non-myopia students. Studies have found that in addition to exposure to light intensity, the occurrence and development of myopia is also related to the co...
