Clinical Evaluation of CATS Tonometer Prism
Prospective, open-labeled, randomized, controlled, multicenter study at two clinical investigative sites in Tucson, Arizona. The subjects will undergo intraocular pressure measurement with the CATS tonometer prism and the Goldmann applanation tonometer prism (GAT).
Of the 200 eyes, at least 10 highly astigmatic eyes (>3 D of corneal astigmatism) each in the low, medium and high IOP ranges shall have the same clinical testing and analysis of results, with the analysis kept separate from that of the main group.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Goldmann Tonometer
Goldmann Tonometer prism will be used as a based line comparator for tolerance assessment versus the active test comparator CATS tonometer prism
|
demonstrate that not more than 5% of the paired differences between the reference tonometer (CATS prism) reading and the test tonometer (Goldmann prism) reading for each pressure range
|
Experimental: CATS tonometer
CATS tonometer prism being used as the test product to assess IOP measurement versus active comparator the Goldmann Tonometer prism
|
demonstrate that not more than 5% of the paired differences between the reference tonometer (CATS prism) reading and the test tonometer (Goldmann prism) reading for each pressure range
