Degree gauge featuring 11.7mm inner diameter with beveled face with marking in 5 degree increments and four notches on internal edge to align with cardinal positions; for use with K3-7912 or K3-7936

The Henderson Degree Gauge features an open 11.7mm diameter design which allows the surgeon to visualize the entire cornea and limbus while marking the axis. Notches at the four cardinal positions coincide with the landmarks produced by the Henderson Alignment Marker (K3-7908), allowing the proper centration and orientation of the gauge. Additionally, the beveled face with lines at 5 degree increments provides excellent visibility without glare for greater accuracy.
