of high attenuation. The prosthetic lens is also thinner, only about 12 mm thick. It is otherwise in the same anatomic position and orientation as a native lens.

It is theoretically possible that a similar appearance may be seen with posttraumatic cataracts with associated spontaneous phacolysis and valious types of phacectomy, as a residual capsular membrane may be present [4]; however, we have not yet encountered such examples.
