Cataract surgery is needed when the clouding of the lens affects normal vision and interferes with work and life. During the surgery, the IOL has to be replaced, and this is all within the normal scope of surgery. Therefore, the medical insurance in each place is within the scope of the reimbursement catalog, and you will be reimbursed according to the medical insurance conditions and reimbursement rate you should enjoy. However, IOLs are consumables, and there are special rules for them. The price of IOLs varies, and the reimbursement rate varies, and the standard is different from place to place. But within this range, the higher the price of the IOL, the higher the reimbursement rate, with reimbursement rates ranging from 90% down to 85%-70%. This decreases in order, meaning that the higher the unit price of the IOL, the lower the reimbursement rate may become, but it is generally reimbursed.
