The Diaton tonometer is the only one in the market that measures the intraocular pressure through the eyelid.

Diaton tonometer is a hand held non contact tonometer device measuring IOP through the eyelid and over the sclera with no contact to the cornea & causing no discomfort to the patient.  This  tonometer masures IOP within seconds without the need for anesthesia or sterilization.

Transpalpebral scleral tonometry has no other  alternative in the world. It is the best method to carry out preclinical medical research of the population and works in complicated clinical cases when it is impossible to use classical tonometry methods.

Diaton is a helpful tool for ophthalmologists faced with pediatric patients or who have corneal abnormalities such as corneal edema, erosions or keratoprosthesis.

Approved by the FDA in 2006, this instrument has been the subject of numerous clinical trials, where it has been found to be comparable with the gold standard, the Goldmann tonometer, and with many other devices.

It’s a safe & easy-to-use screening tool which makes it possible to identify patients at risk for glaucoma & refer them to ophthalmology.

Over 4.5  million people all over the world are blind due to glaucoma and this number is on the rise.
