DESCRIPTION
BS EN ISO 8612:2009
This standard BS EN ISO 8612:2009 Ophthalmic instruments. Tonometers is classified in these ICS categories:
- 11.040.70 Ophthalmic equipment
This International Standard, together with ISO 15004-1, specifies minimum requirements and the design compliance procedure for tonometers intended for routine clinical use in the estimation of intraocular pressure (IOP).
This International Standard takes precedence over ISO 15004-1, if differences exist.
NOTE The true intraocular pressure is seldom directly measured since it would require invasion of the eye. Since the true IOP cannot be clinically measured, alternative methods are specified for determining a reference IOP (Annex A and Annex B).
