Prism Nomograph/Rotation Guide Kit

Now available, a kit that assists you in achieving a combined horizontal and vertical deviation correction by a single prism with its apex placed in an oblique position.
The rotation guide assists in aligning the Press-On prism on the patients lens when rotation is required.
Both the nomograph and rotation guide are printed on an erasable card which can be re-used. 

Included also are step-by-step instructions to ensure the correct prism and angle is identified and the prism is then cut at the correct angle and applied correctly and a fine point non-permanent marker.
