To study the image of contact lenses and intraocular lens implants in vitro and in vivo by CT and MRI prospectively. Soft and rigid contact lenses can be seen in vitro in both methods but in vivo imaging was insensitive. Intraocular lens implants were detected in CT and MRI in vitro. In vivo, intra ocular lens implants were detected in all CT, but were harder to detect by the MRI.
