Cataract surgery for the elderly is generally not free, especially in public hospitals, and even less free, and the conditions for free are very demanding. Generally, it is mainly the elderly people who are in precise poverty alleviation or the five guaranteed households that may be free of charge, but all others are not free of charge. In private hospitals, many times when engaging in seasonal promotions and other promotional activities, they will shout out the slogan of free cataract surgery for the elderly, but in actual activities are not free, but let the elderly choose the more expensive IOLs, which need to pay for themselves, and make up for the cost of surgery. So, nowadays, saying that cataract surgery for the elderly is free is just a publicity stunt, not really free.
