Keratoplasty is a Class III medical device, a rigid gas permeable contact lens with a reverse geometric design. By wearing them, the curvature of the central area of the cornea can be flattened within a certain range, thus reducing myopia by a certain amount, and it is a reversible non-surgical physical orthopedic treatment.
Currently, China has approved the marketing of keratoplasty lenses with a maximum corrective refraction of 600 degrees. The product is mainly for patients who want to maintain good vision without glasses at a certain time of the day. Due to environmental and individual differences, there is still a risk of eye diseases such as corneal endothelial cell reduction and macropapillary conjunctivitis even with proper use of keratoplasty lenses.
If you do not follow the requirements of the fitting, it is more likely to lead to increased ocular secretions, eye congestion, excessive tearing, visual changes, foreign body sensation and other abnormalities increase, which will increase the risk of a number of ocular diseases, such as delayed treatment may also occur permanent visual impairment. In the use of eye discomfort, consumers should receive timely professional treatment. In case of violation of the law, you can promptly report to the food and drug regulatory authorities.
