Marco Tonoref II ARK with Tonometry

Brand: Marco


The Marco Tonoref II ARK with Tonometry saves time and space by combining 3 functions into one device: autorefractor, keratometer, and non-contact tonometer.

Read full product description



The Marco Tonoref II combines the technologies of autorefractor, keratometer, and non-contact tonometer into one highly accurate, space-saving device. The Tonoref II presents several enhanced features such as a smaller footprint, to save even more space, and a new exterior design, but most importantly, the Tonoref II now uses SLD (Super Luminescent Diode) and a highly sensitive CCD device to provide Zonal Ring-Image Technology. This makes it possible to now accurately measure patients with cataracts, corneal opacities, IOLs, and post LASIK.


Multi-Tilt LCD: The clear 5-inch color LCD monitor can be tilted for easy operation. If the operator needs to stand to lift the patient’s eyelid, the monitor can still be viewed.

High Speed Printer: The printer provides fast loading and automatic cutting. Simply open the door, drop in the paper, and go. No spool or paper feed needed.

User Friendly: combines the measurement of refractive power, corneal curvature and intraocular pressure (IOP) providing fast, highly accurate, reliable measurements with significantly reduced measurement time.

Gentle Air: The Tonoref II has an advanced APC (Automatic Pressure Control) – high volume-low pressure puff-function which provides a softer puff of air for accurate IOP measurements with increased patient comfort.

Motorized Chinrest: Up/Down buttons are used to adjust the motorized chinrest to the correct height for patient measurement.
