Abstract: corneal shaping lens is designed for myopia patients with keratoconus and other myopia patients with special corneal diseases. If an experienced ophthalmologist has a problem at the sight of this sentence, it is obvious that the author confused corneal plastic lens with RGP. Although both belong to rigid corneal contact lenses, their images are completely different., The corneal shaping lens is made of breathable hard corneal contact lens material for the treatment of myopia. By using a specially designed corneal shaping lens, the shape of the central surface of the cornea can be changed symmetrically and gradually to reduce myopia. But now there are many dangers of using corneal plastic lenses. How to correctly understand them?, I. corneal shaping lens is designed for myopia patients with keratoconus and other myopia patients with special corneal diseases. If an experienced ophthalmologist has a problem at the sight of this sentence, it is obvious that the author confused corneal plastic lens with RGP. Although both belong to rigid corneal contact lenses, their images are completely different. Corneal shaping lens is mainly used for children with myopia less than 600 degrees. Those who meet the conditions can effectively control the development of myopia and improve naked vision. RGP is mainly used for patients with high myopia and keratoconus above 600. Obviously, what the post says is RGP, not corneal shaping lens., 2. Both FDA of the United States and the State Food and Drug Administration of China stipulate that corneal shaping lens is the third type of medical device. The third kind of medical equipment is the medical equipment with the highest risk level. How can the medical device with the highest risk level (corneal plastic lens) be used for general myopia in children? 1. Firstly, the author also acknowledges that corneal plastic lens is certified by FDA and China’s State Drug Administration, so its legitimacy is recognized. You can search for “corneal plastic lens” on the website of the State Food and drug administration , there is the applicable scope of relevant products, which clearly shows the function of correcting myopia., 2. The reason why it should be classified into the scope of class III medical devices is that the state has strict requirements on this technology, which can not be done by any institution. It belongs to a strict medical behavior. It must obtain the qualification certificate of class III medical devices and carry out it in qualified optometry professional fitting institutions in accordance with relevant national regulations., 3. There is no age limit for the applicable population of corneal plastic lens. The main test rate is the children’s own operation ability. The general requirement is 8-40 years old., III.

corneal shaping lens is made of breathable hard corneal contact lens material, which is used to treat myopia. Through the use of specially designed corneal shaping lens, the shape of the central surface of the cornea is changed symmetrically and gradually to reduce myopia. But now there are a lot about the harm of using corneal plastic lens. How to correctly understand it?
1. Corneal shaping lens is designed for myopia patients with “keratoconus” and other myopia patients with special corneal diseases. If an experienced ophthalmologist has a problem at the sight of this sentence, it is obvious that the author confused corneal plastic lens with RGP. Although both belong to rigid corneal contact lenses, their images are completely different. Corneal shaping lens is mainly used for children with myopia less than 600 degrees. Those who meet the conditions can effectively control the development of myopia and improve naked vision. RGP is mainly used for patients with high myopia and keratoconus above 600. Obviously, what the post says is RGP, not corneal shaping lens.
II. The US FDA and China’s State Food and drug administration all stipulate that corneal shaping lens is the third type of medical device. The third kind of medical equipment is the medical equipment with the highest risk level.
1. First of all, the author also acknowledges that the corneal plastic lens is certified by the FDA and the State Drug Administration of China, so its legitimacy is recognized. You can search the medical device on the website of the State Food and drug administration “Corneal shaping” has the scope of application of relevant products and clearly shows the role of correcting myopia.
2. The reason why it should be classified into the scope of class III medical devices is that the state has strict requirements on this technology, which can not be done by any institution. It belongs to a strict medical behavior. It must obtain the qualification certificate of class III medical devices and carry out it in qualified optometry professional fitting institutions in accordance with relevant national regulations.
3. There is no age limit for the applicable population of corneal shaping lens. The main test rate is the children’s own hands-on operation ability. The general requirement is 8-40 years old.
III. If you are not careful, the corneal plastic lens will make the cornea inflamed, perforated and blind.
aims at this problem, which is also the most concerned one of all parents. Since the introduction of this technology in 1998, millions of people have received this treatment. In the first 2-3 years, due to the lack of medical management and standardized operation, the hospitals carrying out this technology did not have a deep understanding of keratoplasty in the treatment of myopia, the fitting experience and technology were very limited, the compliance of consumers was poor, the exaggerated publicity and misleading of media advertisements and product salesmen, and some unqualified companies and glasses stores also carried out it one after another, The sale of corneal shaping lenses as ordinary commodities has formed a chaotic situation of good and bad, and the relevant parts failed to strictly supervise the quality of corneal shaping lenses, resulting in some serious adverse phenomena of corneal shaping technology among Chinese wearers in the first few years, which has attracted the close attention of relevant domestic and international media. Of course, this problem has a lot to do with the patient’s improper operation and failure to review on time.
and
so now the Internet is full of adverse reactions about wearing corneal shaping glasses. Many of them appear at that stage rather than at this stage. At present, corneal shaping lens has developed to the latest fourth generation product. At present, there are few reports on serious adverse conditions of wearing corneal shaping lens in the media. Qualified optometrists, strict fitting + qualified lenses + qualified users (patients) = safe and effective.
