Non-contact Tonometer

The measurement of intraocular pressure is part of every professional glaucoma screening. The VISUPLAN® 500 from ZEISS makes this examination very easy, and contrary to the Goldmann Tonometry method, does not require contact with the cornea or an anesthetic. Instead, the IOP is measured with a soft puff of air and can be administered by your practice team.

Intuitive operation

The measurement process runs automatically. Simply start the test via the touchscreen and choose from single or multiple measurements. You may also opt to prepare your patients for the exam by initiating a test puff. After testing, the results will appear promptly on the monitor, though you may also choose to print out the results with the integrated thermal printer or export them via the serial interface.
