One advantage of the Visian ICL is that it offers treatment flexibility. If your vision changes dramatically after receiving the implant, your surgeon can remove and replace it. If necessary, another procedure can be performed at any time. Patients can wear glasses or contact lenses as needed following treatment with the Visian 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 Visian ICL.
