Bishop Alignment Prism Set
The Bishop Dual Prism Alignment System is a new tool developed to provide advantages in measuring large-angle strabismus prior to correction. In strabismus, one eye looks directly at the object being viewed while the other eye is misaligned inward (esotropia), outward (exotropia), upward (hypertropia), or downward (hypotropia). When the misalignment of the eyes is large the strabismus is called “large-angle,” referring to the angle of deviation between the line of sight of the straight eye and that of the misaligned eye. Accurately measuring the degree of strabismus using prisms is critically important when preparing for strabismus correction.

Vergence Facility Prism 6D 2D
Vergence Facility testing has been shown to be one of the most important methods of detecting patients with binocular vision disorders and symptoms. Diagnosis of non-strabismus binocular vision abnormalities can be improved through the use of vergence facility testing at near.
