MRI AND INTACS

Q. I live in new york.I have had intacs on my eyes to correct keratoconus. I recently was advised a MRI for my shoulder. My radiologist asked me to check it with a corneal intacs specialist
A. Intacs are ring segments made from PMMA, a kind of plastic. They do not have any metal in them. They come in different sizes. Since they do bot have any metal incorporated it is safe to do a X-ray, ct scan or even an MRI.
