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) ...

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...

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 ...

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...

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.

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.

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).

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.

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

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

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.

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...
