The lifespan of a lens implantation is affected by the age of the individual and how it is used. Typically, after lens implantation in children, the lens will need to be removed and replaced in adulthood; after lens implantation in adults, the lens has a longer lifespan and can theoretically be used for a lifetime if there is no trauma, intraocular infections or other problems. If the implanted lens is young, the implanted lens may not be able to meet the individual’s needs as he or she gets older, and the implanted lens will need to be removed and replaced with a style suitable for adults when they reach adulthood. Therefore, the life span of the lens implanted during childhood is relatively short. Adults who undergo lens implantation have a relatively long lifespan, ranging from 10 to 60 years, if the lens is well used. However, if there are problems such as trauma or infection in the eye during use, it may be necessary to remove the lens for a second implantation. In order to prolong the service life of the lens after implantation, it is important to take good care of your eyes and maintain eye hygiene in order to minimize the chance of eye infections.
