IOLs or lenses implanted during cataract surgery are polymeric materials that are very stable and will not degenerate or change color over time, so these lenses can be used for life and there is no need to worry about their longevity. Unless there are serious lesions after cataract surgery, such as lens dislocation or lens displacement due to eye trauma, only in this case will the IOL need to be removed and reimplanted. Except for these cases, it can be kept in the eye for a long time, and this IOL is very compatible with the tissues and does not cause rejection. Therefore, if cataracts are present in the eye, surgical treatment can be considered and IOLs can be implanted during the surgery, which can effectively improve the vision and meet our normal life needs.
