The price of eye lens implantation surgery, there are two types of lens implantation, one is small incision cataract extraction with IOL implantation and the other is ultrasonic cataract extraction with lens implantation. The cost of small incision cataract extraction with IOL implantation varies slightly from province to province, and in Anhui Province it is about 1700 RMB. For ultrasonic emulsion cataract extraction with IOL implantation, the cost of the procedure is between RMB 1,800 and 1,900. In addition, the surgery requires the use of 3 knives of ultrasound, and the corresponding IOLs as well as viscoelastic. The above consumables, for example, are about 100 RMB for one of the 3 ultra-milk knives, about 300 RMB for the 3 knives, and about 100 RMB for the viscoelastic.
