Myopia, cataracts, glaucoma, etc. are common eye diseases. Among them, myopia is the most common, with more than 1 billion patients worldwide. Cataract disease is the most dangerous and is one of the major blinding eye diseases, with 17 million people worldwide blinded by cataracts. Biomedical materials for the treatment of ophthalmic diseases include contact lenses, intraocular lenses, artificial corneas, artificial lacrimal tubes, artificial eyeballs, viscoelastic agents, artificial tibia, and long-acting medicine films for the eye. In the past three decades, the ophthalmic medical device market has developed rapidly. According to statistics, in 2010 it was 20 billion US dollars, and it is expected to reach 28 billion US dollars in 2017. 　　 International status and market Ophthalmological diseases are medically a major disease, and there are at least dozens of ophthalmic diseases that are currently known. The most common include myopia, hyperopia, presbyopia, astigmatism, cataracts, glaucoma and more. Among the various types of eye diseases, the most common is myopia, and the most dangerous is cataract. At present, the number of patients with global myopia has exceeded 1 billion. About 30% of the population (more than 300 million people) in China suffer from myopia, and the prevalence of myopia in this year has shown a sharp increase in the Chinese youth population, reaching about 80% among the 16 to 22-year-old population. Cataract is one of the world's leading blinding eye diseases. There are currently 17 million people worldwide blinded by cataracts, and this number is increasing by more than 1 million per year. In China, cataract patients have reached about 50 million people. In the past, glaucoma was mainly a disease of the elderly. In recent years, it has begun to show signs of youthfulness. Young and middle-aged people have begun to become a large group of glaucoma patients. In 2012, the number of glaucoma in the world has exceeded 66 million, and the number of glaucoma patients in China has reached 6.5 million. There are currently about 50 million blind patients with corneal disease in the world, and there are 5 million people in China. Foreign corneal donation rate is higher, and China's domestic corneal donation is only about 3,000 cases per year, far from meeting the needs of patients. In the past 30 years, with the development and application of various new biomedical materials and new medical laser equipment, the ophthalmic medical device market has developed rapidly. According to statistics, the global ophthalmic medical device market reached US$17 billion in 2006 and US$20 billion in 2010. It is expected to reach US$28 billion in 2017. The application of biomedical materials in the treatment of ophthalmic diseases covers contact lenses (commonly known as contact lenses), intraocular lenses, artificial corneas, glaucoma implants, vitreous fillers for ophthalmic surgery, viscoelastics, artificial eyeballs, artificial iliac bones, etc. . At present, the largest market is corneal contact lenses for myopia and astigmatism, followed by intraocular lenses for cataract treatment. In 2010, the global contact lens market was 6.1 billion US dollars, the US market was 2.1 billion US dollars, and China was about 300 million US dollars. It is expected that the global corneal contact lens market will increase to US$12 billion in 2017, and the Chinese contact lens market will be close to US$700 million. More than 70% of the global market is currently occupied by products produced by Cibaision, Cooperision, JNJision, and B&L. The current best treatment for cataract treatment is the implantation of an intraocular lens in the removed opaque lens capsule. The global medical device market for cataract intraocular lens surgery was $3 billion in 2010 and is expected to exceed $3.8 billion in 2017. Alcon, Abbott and B&L in the US currently have more than 60% of the global market share. In China, according to the new material “Twelfth Five-Year Planâ€, in 2015, it is estimated that the intraocular lens will need 1.2 million/year.
