Tonometers are used to measure the intraocular pressure (IOP), the fluid pressure inside the eye. The tonometer measures the pressure in millimetres of mercury. The tonometer is an important instrument in the diagnosis and management of Glaucoma. Currently there are no set regulations or guideline for Tonometer's, it is recognised by the MHRA and European Commission (MEDDEV 2.1/5) as a device with a measuring function but there are no guidelines for calibration intervals. The manufacturers of Tonometer's recommend monthly calibration (as per the instruction manual) and recommend Ophthalmologists calibrate their own units at the start of every clinic. However research has indicated that Tonometer's are being used for diagnosis purposes whilst out of calibration and 85% of ophthalmologists do not calibrate their Tonometer's and believe it to be someone else's responsibility (Goldmann tonometer calibration: a national survey, N Kumar et el, 2007).

MM Mercury are communicating with head ophthalmologist, the Welsh Assembly Government, local Universities and the MHRA in order to improve eye health services across Wales (in line with the Welsh Government "Together for Health: Eye Health Care" Delivery Plan for Wales, 2013-2018). We want clearer Tonometer calibration intervals for clinic managers and eye care professionals, education for ophthalmologist regarding equipment management and calibration and affordable preventative maintenance to keep clinics running effectively.

We want Clinic Managers/Ophthalmologists/Teachers and all other eye care professionals to be able to concentrate on delivering high quality patient care, while we take care of the fundamental equipment you use daily.

We hope you share our vision.
