One advantage of the ICL is that it offers treatment flexibility and it is entirely reversible If there is any change is the vision, which is extremely rare, the ICL can easily be removed and replaced. If necessary, another procedure can be performed at any time. Patients can wear glasses or contact lenses as needed following treatment with the ICL. The implant does not treat presbyopia (difficulty with reading in people 40 and older), but you can use reading glasses as needed after receiving the ICL.
