  • Sutureless human eye globe rotation instrument

The present instrument avoids the need for sutures or stitches to rotate the eyeball down, thereby avoiding the possibility of ptosis, and unnecessary wounds and their associated possibilities of hemorrhage, discomfort, slow healing and infection.
