Abstract
A non-invasive, continuous applanation tonometer for measuring intraocular pressure is disclosed. The instrument comprises a flexible contact lens which includes an inflatable applanating chamber; a reservoir of a substantially noncompressible fluid connected to the applanating chamber by a thin, flexible tube; a pump for moving the substantially noncompressible fluid between the reservoir and the applanating chamber; and a pressure transducer to measure the fluid pressure.
