At present, the effective method to treat cataract is surgery, and the choice of intraocular lens in surgery is directly related to the postoperative visual effect of patients. Cataract is a common eye disease, which leads to blurred vision due to lens opacity. The lens, like the "lens" of the eye, plays an important role in human vision.

Cataract surgery must first remove the turbid lens and then implant the intraocular lens. Implanted intraocular lens is not the more expensive the better, but it should be suitable for yourself. Implantation of intraocular lens with appropriate degree and good quality plays a decisive role in postoperative effect.

Intraocular lens is implanted in the eyeball to replace the function of the original lens. Under the same performance, whether domestic or imported, as long as the manufacturing materials are non-toxic, the technology is excellent and the disinfection is strict, the effect is the same after implantation in the eye. Postoperative vision of patients mainly depends on the function of retina, which is not the most expensive or the best.

There are two main considerations in choosing intraocular lens. First, the eye condition. Generally speaking, choose the appropriate intraocular lens according to the condition. Secondly, according to economic conditions, the better the performance of intraocular lens, the higher the price and the more the operation cost. High-end intraocular lens requires high eye conditions.
