We purchased our TONOVET several years ago primarily for equine work. It’s easy, accurate, fast and not probe to artifact. We then started to use it on cats. They are a species that don’t tolerate exam room insults. The greatest insult to a cat is topical anesthesia. It stings when it goes in and the exam is over! Cats tolerate pressure checks with the TONOVET. Birds, reptiles, tortoises and other exotics are the same. Our technicians perform most of the tonometery and much prefer the TONOVET rebound tonometry on all species because of the reliability and lack of artifact. We will be moving to rebound tonometry as a sole means of pressure assessments. I am a convert.
