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. Intr
aocular 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. (C) 1999 Elsevier Science Ltd. All rights reserved.
