Description

The CATS Tonometer Prism (CATS) is a modified Goldmann applanation tonometer (GAT) prism that is optimized to work with the GAT's operating system to reduce errors in the measurement due to patient anatomical variation. This is used to measure intraocular pressure by applying a known force on the globe of the eye and measuring intraocular tension by applanation. Tonometer prisms are assembled onto a GAT as a patient contacting component that is then utilized by the GAT to assess intraocular pressure.
