摘要
An applanating member is provided for use in an applanation tonometer and comprises an optical element (4) replaceably held in a tubular carrier (2). The element is formed as a replaceable plastics moulding with integral means (20,22) for locating it in the member axially and rotationally. Such an optical element can be used disposably so as to achieve higher standards of hygiene without excessive costs.
