From the meaning of the word artificial crystal, we have been the name, that is, synthetic materials made of a special lens called artificial crystal, its composition includes silicone, polyformaldehyde acrylic methyl finger, hydrogel and so on. The shape and function of the IOL is similar to the lens of the human eye, and it is lightweight, high optical performance, non-antigenic, inflammatory, carcinogenic and biodegradable. After cataract surgery, the cloudy lens is removed, and an IOL is implanted into the eye to replace the original lens, so that external objects can be focused and imaged on the retina, and the surrounding scenery can be seen clearly.
1Which IOL is "best"?
Cataract patients want to choose the "best" IOL before surgery, and even think that the most expensive IOL is the best, fearing that the wrong IOL will affect their vision after surgery. We already know that IOLs are implanted into the eye to replace the original crystalline lens, and to focus the image in the original position, so that the eyes can see the objects clearly. Therefore, no matter domestic IOL or imported IOL, as long as the material used to make the IOL is non-toxic, well crafted and sterilized, the effect of implanting the IOL into the eye will be the same. Moreover, the raw materials, production equipment and technology of domestic IOLs are basically the same as those of foreign manufacturers, and the price is much cheaper than that of imported IOLs. Therefore, under the premise of quality assurance, the effect of domestic IOLs and imported IOLs in cataract surgery is the same, and it is not that the most expensive one is the best one.
