For high levels of correction, ICL has been demonstrated to obtain better visual outcomes compared to Lasik and long term data has confirmed safety of this modality.
The ICL is an extra lens, similar to a contact lens. The difference is that the ICL is placed inside the eye, rather than on the surface of the eye. The lens is soft and tiny, much like the natural lens, but does not replace it. The ICL is specially shaped to correct nearsightedness and farsightedness.
As the ICL is tiny and soft, it can be folded up so small that it can be injected into the eye in seconds through a tiny self-sealing opening. Once injected, the ICL unfolds into position in the liquid between the iris and natural lens. ICL corrects the eyesight usually without any further treatment being necessary (the ICL can also be removed or replaced, if required, in another simple procedure).
