Patient: A few days after birth, it was found that the lens of the right eye was partially grayish white, irregular, and the lens of the right eye was a little smaller than the lens of the left eye. However, when he is looking at something, he feels he can see it, just don’t know if the vision is the same as the left eye and how big is the gap right. I don’t know when and how to treat it, the cost of the surgery, whether it can be eradicated, and whether the surgery will have any bad effects on the child in the future. Wang Fengxiang: The surgery should be done as early as possible. Cataract extraction should be done first, and IOL implantation should be done after three years old.
