Metalic particles into the cornea
Dear Friends:

We are working in a Ophthalmology Department at Institut Universitari Dexeus-USP in Barcelona.

We received a patient who was treated for myopia some time ago using a LASIK technique ( Laser In situ Keratomileusis) as you probably know, cornea was sliced and lasered using a microkeratome however blade oscilation in the past eventually spread into the interface particles comming from steel inox blade´s.

Could this affect an MRI of Head, is this a contraindications, ( particles are microscopic/multiple and are interlamellar into cornea )

Thank you for your input

Kind Regards

 For my personal opinion, it is not to expect that these microscopic steel particles are a contraindication for an MRI of the head. An injury of the patient by dislocation or
torque presents not a real risk because of the small size.
The possibility of heating is minimal and can be additional lowered by reducing the SAR. Artifacts may reduce the image quality a little, but diagnostic brain imaging is certainly possible. The use of a mid or low field MRI machine will also reduce any risks.
Hope this will help.
