Whether or not the lens implantation can last a lifetime can be judged according to the individual’s health condition. Most people can last a lifetime after the lens implantation surgery, but a small number of patients need to remove the IOL if they have cloudy lens or IOL loss after the implantation of the lens. IOL implantation is suitable for patients with myopia, hyperopia, cataract and other eye diseases. Before the implantation of IOL, patients need to be tested for fundus, intraocular pressure and myopia (hyperopia), and only those who meet the criteria for the surgery can undergo IOL implantation. IOLs are biocompatible and can last for a lifetime. If the IOL is implanted and becomes cloudy or dislocated, it is often necessary to remove the IOL to improve vision and promote recovery. It is recommended that patients follow the doctor’s instructions for care after IOL implantation, have regular checkups, and seek prompt medical attention when discomfort occurs.
