Canon TX-20P Non Contact Tonometer/Pachymeter

Description

Canon TX-20P 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 for evaluating ocular conditions that affect intraocular pressure, 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.

A Fully Automatic, non-contact tonometer combined with a Pachymeter. The TX-20P is a multifunctional ophthalmic instrument that measures IOP and Central Corneal Thickness, then automatically calculates the corrected IOP.

FULLY AUTOMATIC NON CONTACT TONOMETER & PACHYMETER

Two in one: tonometer and pachymeter in a single instrument.

Information about the actual corneal thickness is important because without, it can mask accurate readings of IOP and delay diagnosis of glaucoma. Unless taken into account, thicker corneas contribute to overestimation of IOP values and thinner corneas to underestimation.

With a simple button press, an examination will be conducted fully automatically on both eyes – from alignment to printing.

Selectable Measurement Modes

The 3D tracking system of the TX-20P features a wide range of movement, so that the examinee’s pupil can be detected easily. In Full Auto mode, the TX-20P offers one-touch 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-20P also includes Auto and Manual measurement modes.

Visual Reliability & Indicators

When a reading cannot be made, the TX-20P 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 of the next action to take, such as adjusting the chin rest or limiter.

Warning Images

Limiter Function

Pachymeter

Central corneal thickness (CCT) measurement based on a cross-sectional image of the slit image of the cornea. With the built-in pachymeter, the TX-20P is much more than just a tonometer. It reduces the risk of misreading intraocular pressure and is set to make a significant contribution to detecting potential glaucoma in patients.

Soft Air Puff & Position Safety Alert

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

Multifunctional Color LCD Monitor

The 5.7-inch color LCD monitor tilts 40°, making the TX-20P easy to use whether the operator is sitting or standing. The clear LCD display also includes multi-functional screen buttons allowing the operator to switch menus as needed.

External Fixation

External fixation is effective for patients with central vision defects and can be activated via the menus on the LCD screen.

Motorized Omni-Directional Joystick

Aligning patients is easier with the motorized omnidirectional joystick and a fine-focus dial. All positioning may be performed with one hand allowing the other hand to work with the patient, if needed. The top of the joystick includes the start button, which can be pressed immediately once the patient is properly positioned.

Input & Output Modes

The TX-20P provides data output via RS-232C and LAN connections, and data input via USB.

Printouts & Fast Built-in Printer

Internal memory provides storage for up to 10 measurements for each eye, listed in the order they were taken or by reliability. A printout can be set up to automatically print. The front-loaded built-in printer includes an auto cutter, making it simple to remove the print-out. New paper rolls can easily be inserted through the feeder.
