ICLs are designed to be a permanent implant, and many patients enjoy clear vision for many years after the procedure. However, there is no guarantee that an ICL will last a lifetime. Some patients may experience a loss of clarity or other vision changes over time, and in some cases, the lens may need to be replaced. The lifespan of an ICL can depend on a variety of factors, including the patient’s age, overall eye health, and the quality of the initial implantation.
