The Canon TX-20 Full Auto Tonometer easily measures Intraocular Pressure (IOP) allowing doctors to perform simple eye exams efficiently while enhancing patient comfort with a soft air puff. This test is important in evaluating ocular conditions that affect the pressure inside of an eye, such as Glaucoma. Whenever high IOP is detected, a warning message is displayed. The operator can enter any threshold value on the unit’s settings screen to activate the warning system for that value. The TX-20 Tonometer is compact and lightweight at approximately 33 pounds, making it easy to transport and install.
