title: Choyce intraocular lens placement under gonioscopic control.
abstract: Various gonioscopic lenses were tested in the operating room for viewing the size and foot placement of the Choyce Mark VIII intraocular lens. The Tennant and the Worst fiber optic devices were fairly adequate. The Thorpe surgical gonioscope was the easiest to handle, and provided a good view with the operating microscope.
