China News Online, September 18 (Wu Wenjing) "The 20th International Conference on Ophthalmology" and "The 20th International Conference on Optometry" (COOC 2020) were held in Shanghai on the 18th.
The latest survey results released by the Chinese Ministry of Education at the end of August have received widespread attention.
A survey conducted by the Ministry of Education of 14,532 people in 9 provinces showed that compared with the end of 2019, the myopia rate of students increased by 11.7% in the past six months, of which the myopia rate of primary school students increased by 15.2%, the myopia rate of junior high school students increased by 8.2%, and the myopia rate of high school students increased. 3.8%.
Liu Yue, an associate professor at the University of California, Berkeley School of Optometry and founder of the Berkeley Myopia Prevention and Control Clinic, believes that this may be largely related to the decrease in children's outdoor activities during the new crown pneumonia epidemic and the increase in the use time and intensity of electronic products.
It should be pointed out that in recent years, the prevalence of myopia has shown a rapid growth trend in China.
Studies have shown that the prevalence of myopia in the 18-year-old population has increased to 80%-90%.
To this end, Cooper Optics released MiSight® 1 Day clinical trial data during the conference, hoping to provide enlightenment for Chinese ophthalmology and ophthalmology professionals and public health related functional departments to deal with the severe situation of the rapid development of adolescent myopia.
According to reports, this is a soft contact lens specially used to slow down the development of myopia in children.
Cooper Optics' prospective multi-center randomized double-blind clinical trial enrolled 144 myopic children between 8 and 12 years old in Asia, North America and Europe.
The experiment quantitatively evaluated the effect of the daily disposable soft contact lens compared with the single-focal daily disposable soft lens in controlling myopia in adolescents over a three-year period.
Taking the relative change of the average refractive power (mydriatic refraction equivalent spherical power) as the curative effect index, the test found that the soft contact lens can delay the development of myopia by 59%; the relative difference in the average eye axis growth is used as the curative effect index to control myopia. The effect reached 52%.
After peer review, the trial results were recently published in the journal Optometry and Vision Science under the title "Three-year clinical trial of MiSight lenses for myopia control".
In addition, the three-year results showed that the dual-focus design contact lens is highly accepted by pediatric patients, and has no significant impact on their daily life such as school activities, reading, outdoor sports, and computer use compared with the control group.
During the three-year follow-up period, there were no significant reports of slit lamp signs and no significant ocular adverse events.
In addition to sharing trial results and follow-up research, Daniel McBride, President of Cooper Optics, said that he will continue to cooperate with global ophthalmologists, optometrists and medical and health authorities, including China, through conference participation, research support and clinical training activities. , To jointly promote the research, education and evidence-based treatment of myopia management.
