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.

Features:

Selectable Measurement Modes 

The three-dimensional tracking system of the TX-20 Tonometer features a wide range of movement, so that the examinee's pupil can be detected easily. When in Full Auto mode, the TX-20 Tonometer is a one touch operation for IOP measurement for both eyes. Just press the start button and the unit automatically aligns and measures the intraocular pressure of both eyes. For added flexibility, the TX-20 Tonometer also includes Auto and Manual measurement modes.

Soft Air Puff & Position Safety Alert 

For many patients, the only thing significant and worrisome about tonometry is the air puff. The TX-20 Tonometer employs a delicate air puff for patient comfort. When the Safety Alert is set, the TX-20 Tonometer automatically prevents the optical head from making physical contact with the patient.

Visual Reliability & Indicators 

When a reading cannot be made, the TX-20 Tonometer display will show a snapshot of the examinee's eye along with the measurement error. The operator will know immediately whether it was an eyelid, eyelash or the eye being out of position that caused the error. The operator will then be informed on the next action to take such as adjusting the chin rest or limiter.

External Fixation 

The external fixation is effective for patients with central vision defects and can be activated using the menus on the LCD screen.
