Estimating the term…
For calculating the intraocular pressure (IOP) of an eye, an applanation tonometer comprises an applanator formed of an optics array, a force transducer, an image sensor, and a processing circuit configured to calculate an intraocular pressure of the eye using one or more pairs of measured force and applanated area. The tonometer is provided with a disposable tip that covers the applanator, thereby providing a replaceable, sterile and transmissive interface between the tonometer's applanator and a patient's eye. Preferably, the applanating surface has a matte finish. The tonometer calculates the intraocular pressure using a predetermined relationship between interocular pressure and the slope of the line defined by data relating to the forces required to applanate the eye and the geometry of applanated portions of the eye. In a preferred embodiment, the data acquisition is synchronous. The tonometer may be of the type of a portable, hand-held device or a device affixed to and used in conjunction with a slit-lamp design. Also disclosed is a method and device for applying a disposable tip to the applanator.
An applanation tonometer for measuring an intraocular pressure of an eye, comprising:
An applanation tonometer comprising:
A method of determining an intraocular pressure of an eye comprising:
A disposable tip for use with an applanation tonometer, the tip comprising:
A disposable tip for use with an applanation tonometer wherein the applanation tonometer includes an applanator having a polished smooth surface, the tip comprising
A disposable tip for use with an applanation tonometer further comprising an attachment mechanism for detachably attaching the tip to a tonometer.
An applanation tonometry system comprising:
A method of forming a disposable tip on a distal end of an applanator of a tonometer comprising the steps of
A disposable tip for a distal end of an applanator of a tonometer comprising a small sheet of thin film secured onto a distal end of an applanator via an elastic member.
