Description
Chenghai Wang and co-authors present a 2025 comparison of three devices that measure pressure inside the eye. Rebound tonometers tap the cornea with a tiny probe and read the bounce; they are quick and need no drops. Three brands were tested head to head in rabbits.
Pressure in ten rabbit eyes was set by a saline column from about 11 to 86 millimeters of mercury. Each device took readings across that range, giving 298 data sets in all. Average readings from the three agreed closely, and all tracked the true pressure well. Small trends differed: one read slightly low at high pressure, another crossed over near the low twenties. The new iFalcon device proved stable. The authors advise care when switching brands mid-study.
