Diaton Glaucoma Tonometer

The Diaton Tonometer is a revolutionary, non-invasive glaucoma screening device that measures intraocular pressure (IOP) through the eyelid (transpalpebrally), bypassing the cornea entirely. Unlike traditional tonometers, the Diaton eliminates the need for topical anesthesia, eye drops, or direct corneal contact, making it a safe, quick, and patient-friendly solution for routine glaucoma screening and IOP monitoring.

Manufactured by BiCOM Inc., the Diaton Tonometer is ideal for use in a variety of settings, including primary care, optometry, ophthalmology, emergency rooms, and field screenings, especially where sterile conditions or access to complex equipment may be limited.

Key Features & Benefits:

• Transpalpebral Technology (Through-the-Eyelid Measurement):

  • Measures IOP without touching the cornea, reducing the risk of infection or complications.

  • Ideal for patients with corneal pathologies, post-surgery, contact lens wearers, and children.

• No Drops or Anesthesia Required:

  • Completely painless and non-invasive, enhancing patient comfort and compliance.

  • Simplifies the workflow and allows for rapid screening in busy clinical or outreach environments.

• Portable & User-Friendly:

  • Lightweight, handheld design makes it suitable for bedside use, field screenings, and mobile clinics.

  • Digital LCD display with intuitive controls for fast and accurate readings.

• Accurate & Reliable Readings:

  • Proven clinical performance in a wide range of patient populations.

  • Reduces false readings caused by corneal abnormalities or recent eye surgeries.

• Cost-Effective & Low Maintenance:

  • No need for disposable covers, calibration fluids, or frequent maintenance.

  • Long-lasting device with minimal operational costs.

Applications:

• Glaucoma screening and monitoring

• IOP measurement in patients with corneal disorders

• Pediatric and geriatric eye care

• Mobile and field-based eye health programs

• Emergency and post-operative settings
