First of all, there is no economic, safe and effective international standard for the surgical treatment of moderate and severe floaters. Many people with floaters go to the hospital, and doctors are actually helpless. What they can do is to appease the patients and tell them to ignore what is in front of them and divert their attention. If the number increases to an unbearable level, they will check and evaluate it. Secondly, it is not that we don't pay attention to it, because the current medical means are not enough to solve the disease well, and there is a high risk of sequelae. The existing methods, such as YAG laser, are only used to try to treat patients who are extremely troubled by floaters. Strictly speaking, this surgical method is not to remove floaters in the eyeball, but only to remove or deviate from the visual axis. The limitations of this method are actually controversial in the medical field. In addition, YAG laser can also cause some complications that damage vision, such as macular damage, retinal detachment and cataract, which have been reported in clinic. Compared with floaters, these diseases are much more serious. Considering the pros and cons and risks, YAG laser is not popular, and other surgical methods such as vitrectomy also have the risk of serious complications. Finally, let's be happy and look forward to the future. There are some new ideas and methods in the medical field at home and abroad. Not long ago, at the APAO20 17 (Asia-Pacific Ophthalmology Society Conference), Dennis Lam, a Daniel in the field of ophthalmology, mentioned a future treatment trend of floaters: the use of cataract phacoemulsification anterior segment glass cutter for treatment, which received good clinical feedback in some areas. The operation process of this method does not exceed 10 minutes. DL Daniel has done more than 200 cases, and 95% of the patients are satisfied. So far, there is no sequelae. If you are interested, you can look over this paper by Daniel. Imagine that cataract needs to be mature to operate, and now it can be operated as soon as possible. In the future, floaters will be 10 minutes.
