Optometrists at all 4 practices at Optivision have passed a national qualification that allows repeat IOP's to be measured using the gold standard of Goldman applanation tonometry. This is carried out if the IOP is found to be over 21mmHg using any other method of tonometry.


Tonometry is the procedure carried out to measure IOP.

The Pulsair blows a little puff of air on to the front of the open eye to measure the pressure. No anaesthetic drops are required.

The Pulsair

This is the gold standard for measuring eye pressure. Anaesthetic eye drops have to be used to numb the cornea. A small probe is then placed onto the eye to measure the intraocular pressure.

The Goldman

This test measures the pressure inside the eye. High intraocular pressure can be associated with glaucoma. It is usually performed on those over the age of 40 or with a family history of glaucoma. There are several instruments to measure the intraocular pressure.

The Icare

The tonometer is based on a new measuring principle, in which a very light probe is used to make momentary contact with the cornea in slow motion. The measurement is barely noticed by the patient and often does not even cause corneal reflex. The single-use, disposable probe guarantees microbiological safety.
