The price range for glaucoma surgery is relatively large, generally requiring between 4,000 and 15,000 RMB. The difference in price depends mainly on: i) the indications for the type of surgery used for glaucoma; ii) the type of intraoperative anesthesia; iii) whether implantable materials or medications are needed; iv) the level of the hospital where the surgery is received, with tertiary hospitals charging higher fees than secondary hospitals; v) and also the price in different provinces. In addition, if the glaucoma patient also suffers from other diseases, they may have to be controlled at the same time, and the cost will increase accordingly. Therefore, the specific cost of glaucoma surgery will depend on the specifics of the condition.
