Patient Question: Disease: Can I add IOLs for congenital low vision. Description：I am congenital low vision, left and right eyes are 1500 degrees myopia, astigmatism around 200 of 400. hope to provide help: please ask me can I implant an IOL to improve vision? Wang Huaizhou, Glaucoma Department, Peking Tongren Hospital, replied: IOL implantation is equivalent to making the outside of the spectacle lens smaller, smaller than the contact lens, and put it into the eye, so that once and for all, the lifetime without having to adjust the glasses. However, it is only suitable for patients who wear glasses to correct their vision well. The vision after surgery is generally slightly better than that corrected by frames, but the visual quality is better than that of frames because there is no distortion of vision. Surgery is not effective if frame glasses do not correct vision.
