Reichert Tono-Pen VET — Used Veterinary Applanation Tonometer

The Tono-Pen VET reads IOP from 5 to 80 mmHg, runs on 2 Ocu-Cel VET batteries, and is validated across more than 40 dog and cat breeds along with widely used in equine, exotic, and zoo medicine. The handheld form factor (6.25″ long, 71 g) means a single technician can capture IOP on a fractious patient in seconds without a slit lamp setup.
Per a National Library of Medicine-indexed study (Vet Ophthalmol, 2015) directly comparing the Tono-Pen Vet applanation tonometer with the TonoVet rebound tonometer in dogs and cats, the Tono-Pen Vet remains the established applanation reference for veterinary IOP measurement.
Why Veterinary Practices Choose the Tono-Pen VET
Validated across 40+ dog and cat breeds — clinically proven calibration; not a repurposed human tonometer.
- Applanation reference, not rebound — clinicians who want the Goldmann-correlated measurement methodology rather than the bouncing-probe rebound approach.
- 5–80 mmHg range — covers normotensive and glaucomatous animals plus the broader exotic/zoo range.
- Handheld and self-contained — no slit lamp, no chair-stand, no exam-lane setup; works at the patient regardless of restraint position.
- Disposable Ocu-Film+ tip covers — minimizes cross-contamination between species and patients.
- Battery-powered — 2 Ocu-Cel cells last hundreds of measurements; no daily calibration step.
- Reads in seconds — short measurement window critical for patients who won’t tolerate prolonged restraint.
Clinical Applications
- Routine glaucoma screening in companion animal practice (dogs, cats)
- Equine ophthalmology — IOP capture during ambulatory and barn exams
- Exotic and zoo medicine — birds of prey, reptiles, primates where slit-lamp work is impossible
- Pre- and post-surgical IOP monitoring (cataract, glaucoma, intraocular procedures)
- Sedation/anesthesia monitoring in patients undergoing prolonged general anesthesia
- Field/farm calls and mobile veterinary practice
Who This Is For
- Veterinary ophthalmologists building or replacing handheld IOP capability
- General veterinary practices wanting to add glaucoma screening without a slit-lamp investment
- Equine veterinarians needing a portable, durable IOP tool for ambulatory work
- Zoo and exotic medicine teams measuring IOP across diverse species
- Veterinary teaching hospitals and residency programs needing a clinical workhorse
