Background

An artificial lens is a special lens made of artificial synthetic materials, and comprises silica gel, polymethyl methacrylate, hydrogel and the like. The shape and function of the artificial lens are similar to those of human eyes, and the artificial lens has the characteristics of light weight, high optical performance, no antigenicity, inflammation, carcinogenicity, biodegradability and the like. The cloudy lens is removed after cataract surgery, and the intraocular lens is implanted into the eye to replace the original lens, so that the external object is focused and imaged on the retina, and the surrounding scenery can be seen clearly. Intraocular lens (IOL) implantation has evolved over half a century to become a conventional means of treating lens disorders such as cataracts. The original lens is removed by means of extracapsular extraction or phacoemulsification, and then an IOL capable of replacing the refractive function of the original lens is implanted, so that the vision of the patient is recovered. With the continued advancement of cataract surgery and IOL manufacturing techniques, there is an increasing demand for the therapeutic effects of IOL implants, which have been limited initially to regaining vision, and which have evolved to achieve more comprehensive and better vision, and even to restore vision levels in healthy young people.
