The cost of a trifocal IOL implant is usually around $20,000 dollars. The advantage of trifocal IOL compared with traditional IOL is that patients can see clearly no matter whether they are looking at far, near or intermediate distance, unlike monofocal IOL which can only see far, but blur when looking at near, and need to wear myopia glasses for correction. However, the cost of the trifocal IOL itself is relatively high, usually ranging from $15,000 to $20,000, and with the expenses required for hospitalization, the overall cost is around $20,000 yuan. Patients also need to be examined first to determine if their eye conditions are suitable for trifocal IOL implantation. For example, if there is a subluxation of the lens, or if the pupil is too small, then the implantation of a trifocal IOL is not suitable. The cost of IOL implantation is also related to the price level of the region and the level of the hospital. You need to consult the local hospital for the exact cost.
