"all intraocular lens implants are considered MRI safe up to 3 tesla 7. A study of 21 IOLs in 2012 found no significant torque of the implants in a 7 T field, nor any appreciable heating effect. Susceptibility artifacts may be seen with IOLs that contain platinum in their haptics 5."
"Generally all intraocular lens implants consist of two main elements: the optic, which is the functional lens element, and the haptics (or footplates) that hold the optic in situ. The implant is generally impervious to fluids and therefore does not enhance post-contrast administration."

"Structure"
"The first intraocular lenses were made from polymethylmethacrylate (PMMA), an inert plastic, this has now been superseded by flexible synthetic materials, e.g. acrylic and silicone (hydrogel), such that lenses are usually now folded, allowing a smaller incision in the lens capsule, and unfolded once inside the capsule."
