The price of cataract surgery varies mainly according to the function and brand of the selected lens, the surgical method, the level of the hospital and local policies, with the price ranging from one thousand dollars to tens of thousands of dollars. Due to the national cataract sight restoration project and other programs, the IOLs are heavily subsidized, so if you choose a basic domestic IOL, it costs one or two thousand dollars, or even less because of some local policies. If you want to choose more advanced, stronger or imported lenses, most of them cost tens of thousands of dollars. The most popular cataract surgery is the extracapsular ultrasonic emulsification, which is less invasive, has a shorter recovery period, and is less expensive than intracapsular extraction. Intracapsular extraction is more commonly used in cases of severe trauma and is more expensive due to more tests and treatments and a longer recovery period. Prices also vary depending on the level of the hospital and local policies. The cost of cataract surgery is determined on a case-by-case basis.
