The position of the posterior chamber intraocular lens.

Six human cadaver eyes were used for intraocular lens (Shearing) insertion, and the results were photographed. It was found that with the posterior capsule intact, insertion was relatively simple and the feet were found to lie in the ciliary body sulcus with good fixation. Some decentering was common and difficult to correct, but not optically important. With the posterior capsule torn or missing, misplacement was common. After correct insertion, the lens was well fixated without pseudophakodonesis, and there was still found to be room for an additional 1.5 to 2.0 mm of movement.
