The cost of surgery is related to the crystal chosen, and as of December 10, 2019, on the domestic market, an IOL, the price of which ranges from a high of nearly $10,000 to a low of only a few tens of dollars.
IOLs are high-value medical devices, and companies have a high degree of autonomy in pricing. At present, the domestic market, an artificial crystal, the highest price of nearly ten thousand yuan, the lowest only a few dozen dollars. Experts say the choice of IOL varies from person to person.
The IOL, also known as an artificial lens, is a precision optical component that is surgically implanted in the eye instead of removing its own cloudy crystals, and is mainly used for cataract removal surgery and IOL implantation. Currently, IOLs on the market range in price from tens of dollars to tens of thousands of dollars according to different materials, functions and brands, and are generally categorized into four types, namely, ordinary IOLs, folded IOLs, adjustable folded IOLs (multifocal folded IOLs), and aspheric IOLs, according to their functions.
Many cataract surgery patients have a headache in choosing a "cost-effective" IOL. Dr. Xing Xiaoli, deputy chief ophthalmologist at Tianjin Medical University Eye Hospital, said that ophthalmologists usually choose the type of IOL according to the patient's condition, and then the patient decides which price and brand of IOL to choose according to his or her own financial situation, but they do not recommend it, or even replace the patient to make a choice.
Many patients believe that the more expensive the better, but this is not necessarily the case. High-end IOLs can cause problems for patients when they have other related diseases besides cataracts. High-end IOL implantation is more demanding on both the doctor and the patient. The cornea itself has a scar, will produce irregular reflections, then, even if the most expensive multifocal crystal installed instead of bringing unnecessary trouble.
