The recent discussion about myopia surgery is because Cai Ruifang, an authoritative ophthalmologist in Taiwan Province Province, personally announced that he would no longer engage in myopia surgery. The reason is that Dr. Cai does have complications such as glare, decreased night vision and dry eye after surgery. Recently, he treated more than a dozen cases, mostly middle-aged people in their 40 s and 50 s. In a short time, their vision was obviously weakened, which was suspected to be related to the inability to close the corneal flap and long-term inflammation. Therefore, he decided to stop this operation to prevent the injury from expanding. And he himself introduced myopia surgery to Taiwan Province province, so there was considerable discussion about his announcement among the three places.
