Perkins Tonometer Mark 3, For Clinic, Hospital

  The Perkins Tonometer can be used where other types of tonometer cannot. Post operative and bedridden patients in particular are difficult to examine by traditional methods or non-contact methods. The Perkins Tonometer is therefore a primary choice for many practitioners. The same prisms and test standards as the Goldmann Tonometer are used. Precision counter-balanced movements allow readings to be taken with the patient in any position without affecting the results. Every instrument is supplied with a signed and dated certificate of accuracy
