The ICL is an ultra-thin contact lens that can be inserted into the space between the own eye lens and the iris. The procedure is usually performed under drip anaesthesia. However, only one eye is operated on at a time. The second eye follows 7-14 days later.
Higher refractive errors can be treated than with LASIK. The treatment is reversible; if necessary, the ICL can be removed again. Patients do not suffer from additional dry eyes after the procedure. The accommodation remains intact, as with LASIK. When the own eye lens is exchanged, as with Refractive Lens Exchange (RLE), the natural accommodation capacity is lost.
