Consistent measurement results
The Perkins Mk3 Tonometer hand-held applanation tonometer combines the same proven accuracy as the clinically trusted Perkins Mk2, but with an improved ergonomic design, longer lasting battery and excellent internal LED illumination.
Ergonomic design
Innovative LED illumination
‘Tonogrip’ prism holder
Integrated rechargeable battery
Tonosafe compatible
Clinically trusted accuracy
Improved LED illumination for an enhanced image
Innovative built-in LED illumination produces an enhanced image of the tonometer mires, permitting use regardless of ambient lighting conditions. It also produces lower operating temperatures, giving greater comfort to both the operator and the patient. In conjunction with the longer-lasting battery, less energy is required, so increased operating times of the Perkins tonometer are achieved.
Precision counter-balanced movements; convenient, safe and accurate
The hand-held Perkins tonometer is comfortable to hold and well-balanced. It has been specifically designed to examine patients who have often been difficult to assess by traditional applanation tonometry methods. These include; bed-ridden, wheelchair-bound, paediatric and community-based patients.
Goldmann applanation tonometry; use disposable or reusable prisms
The Perkins tonometer is compatible with both reusable Goldmann tonometer prisms and Haag-Streit Tonosafe disposable tonometer prisms. The easy-to-use ‘Tonogrip’ tonometer prism holder allows for straightforward placement of both sterilised Goldmann prisms and Tonosafe prisms.
