Tonometers

A tonometer measures intraocular pressure (IOP) — the key metric for glaucoma screening and management. Accurate, repeatable IOP readings are essential in any optometry or ophthalmology practice, making a reliable tonometer one of the most frequently used instruments in the exam room.

Several types are in common clinical use: non-contact tonometers (NCT or air-puff) are fast and require no anesthesia, making them ideal for high-volume screening; handheld and rebound tonometers like the TonoPen offer portability for bedside or mobile use; and applanation tonometers remain the gold standard for precision in specialist settings. Digital Eye Center carries a rotating selection of used and refurbished tonometers across all major types, from manufacturers including Reichert, Nidek, Topcon, iCare, and Diaton. Condition varies by unit — each listing specifies whether it is used or refurbished, and every unit is verified by a certified technician before shipping.
