A Combination Horizontal & Vertical Prism Bar precisely measures a condition known as ocular deviation, where the eyes aren’t properly aligned. It is made of two parts: a horizontal prism bar and a vertical prism bar.
The horizontal component can move along a channel attached to the vertical bar, ensuring both bars stay flat and at right angles to the observed object.
This tool can be used independently or together with other ophthalmic equipment. It’s accurately calibrated for two purposes: maintaining consistent results for the same eye condition and measuring both primary and secondary deviations—indicating improper eye alignment.
