Clement Clarke originally developed the popular Perkins tonometer during the 1970s. Over time, it has been updated and improved, creating an ergonomic design, as well as giving the instrument an integral rechargeable battery.
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 & 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 sterilized Goldmann prisms and Tonosafe prisms.
