| description | Applanation tonometers.
An applanation tonometer with a replaceable prism for contacting a cornea has emitter and detector ports arranged opposite each other on opposite sides of a longitudinal axis, with the ports aimed at about 45° to the longitudinal axis. Light from an emitter confronting one of the ports is incident on the applanation surface at about 45° so that light reflecting internally of the prism from the applanation surface is directed toward the opposite port for detection. The portion of the light internally reflected from the applanation surface provides a signal indicating the size of the applanated area, from which intraocular pressure is determined. |
