Technical Spec.

Goldmann applanation tonometry is the gold standard for accurate and reproducible measurement of the intra ocular pressure. The AT 900 tonometer fits all Haag-Streit slit lamps and most copies (contact Haag-Streit service for more information on adaptation possibilities). There are special mounts for every Haag-Streit slit lamp available, ensuring the best ergonomic operation of the tonometer on the slit lamp.

The AT 870 tonometer fits most Zeiss-type slit lamps. In its “ parked ” position it does not interfere with normal diagnostic use of the slit lamp.

Haag-Streit Goldmann applanation tonometers are the most cost efficient solution to measure intra ocular pressure. The competitive price, durability and minimal need for maintenance, paired with the reusable tonometer prisms, ensure a good return on investment. For use with infectious, or other “ special ” , cases we also offer a disposable prism – “ Tonosafe ” .
