Surgical treatment for senile cataract patients usually costs from $5,000 to $20,000, depending on the type of IOL chosen and the area and hospital visited. Age-related cataract is a degenerative change of the aging lens, which is the result of a combination of factors such as age, occupation, gender, ultraviolet radiation, etc. Surgery is the main treatment to remove the degenerated lens and then implant a transparent IOL to restore vision. The cost of cataract surgery mainly includes the hospitalization fee for surgery and related examination and medication change, as well as the cost of the IOL implanted inside the eye. The price of the implanted IOL can vary greatly, ranging from $1,000 to $15,000, and there are even more expensive IOLs. Prices can also vary from region to region and from hospital to hospital. So overall, patients can expect to pay anywhere from $5,000 to $20,000 for cataract surgery. It is recommended that patients go to the ophthalmology department of their local hospitals for detailed consultation, and choose the right hospital and IOL at the right price under the guidance of their doctors according to their actual situation.
