Which tonometer has the advantage of being portable, fast, and comfortable to hold?

• A. Goldmann Tonometer
• B. Tono-Pen
• C. Icare Tonometer
• D. Reichert Tonometer

Answer: (B)

The device that best fits portable, fast, and comfortable use is the Tono-Pen. This handheld instrument is compact enough to hold in one hand and take out in various settings, from small clinics to bedside checks, without needing a slit lamp or extensive setup. The measurement is quick—typically just a few seconds—so you can obtain multiple readings rapidly and move on. The probe tip is small and designed for brief corneal contact, which tends to feel more comfortable for patients than the longer, more involved process required by bench-mounted tonometers. While other tonometers have their own advantages, the Tono-Pen’s combination of handheld portability, speed, and ease of use makes it the most suitable choice when those attributes are the priority.
