New equipment for measuring intraocular pressure have been introduced lately. One of these is the Keeler Pulsair non‐contact tonometer which uses pressurized air in measurement. It is found to be safe and easy to use in practice, but it seems to give 1.5–2.0 mmHg lower reading than the Goldmann applanation tonometer. This was confirmed by the present study, where non‐contact tonometry was controlled by applanation tonometry with a 2–3 week delay between the measurments. However, for screening procedures the accuracy of the apparatus can be considered as sufficient.
