• A curved, hinged ruler for measurement along the surface of the globe during strabismus surgery has been designed. A modification of a previously described curved ruler, the current model has a hinge for greater ease of maneuverability and a "T" piece on one end to facilitate measurement and marking of both poles of the muscle without repositioning the ruler.
