When the IOL is not damaged and there is no eye disease involving the IOL, the IOL can generally last a lifetime. When the cloudiness of the lens affects the vision, you can choose to have an IOL implanted, and most of the lenses used have good stability, so the IOL can be used for a lifetime in general and does not need to be replaced. However, when pupil dilation, uveitis or eye trauma occurs, the IOL may be dislocated or shifted, thus affecting the service life of the IOL. It is important to protect your eyes from eye trauma and eye diseases in your daily life, and to go to the hospital for regular checkups.
