• A practice surgery device used for training novice ophthalmic surgeons employs an inflatable bladder that supports a human bank scleral shell. The sclera is used for placement of sutures. A.light source and universal joint to support a syringe are mounted on a 25 × 15-cm base. Glycerin-preserved sclera is available from many eye banks. Up to 100 practice sutures may be placed in each scleral shell. This device allows the beginning surgeon the opportunity to obtain a feel for needle passage through tissue. Technique for the use of loupe or microscope magnification can also be developed. In addition, a deflation of the scleral "globe" occurs when a needle is placed too deeply. This emphasizes the need of superficial suture placement.
