It depends on the surgical method and hospital you choose. Different levels of hospitals charge different fees, and so do private and public hospitals. Generally speaking, the cheapest one is only a little more than 2,000 to 3,000 yuan, but it is used for extracapsular cataract extraction. Because non-folding intraocular lens can be used for extracapsular cataract extraction, the cost is low, and it is usually done by bright train or the like. Phacoemulsification for cataract varies from 3,500 to15,000, mainly using foldable intraocular lenses. There are many kinds of intraocular lenses, including blue light crystals, aspherical crystals, multifocal crystals, and even recently, crystals with adjustment function. These crystals range from 1000 yuan to more than 8,000 yuan, so the prices vary greatly. Before operation, you can consult an ophthalmologist about the specific functions of these crystals and choose them according to your own needs and economic conditions.
