Surgical practice kit. Ophthalmic suture simulator
E. M. Helveston and A. C. Coffey
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 X 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.
