Performance

Bringing Goldmann Applanation Tonometry to Everyday Clinical Practice

The AT-2 is designed for TAKAGI slit lamps and is compliant with ISO 8612 requirements. Goldmann applanation tonometry is employed to help ensure stable and reliable IOP measurement.

The S12-18 Measuring Prism is made of methacrylic resin, an optical plastic material known for its exceptional hardness and high transparency, for enabling bright and clear observation.

Integrated Design for Easy Cleaning

The S12-18 Measuring Prism features a seamless groove-free design integrating the corneal contact surface and surrounding area, allowing easy cleaning and repeated use.

Two S12-18 units are included as standard with the AT-2.

Streamlined Clinical Workflow

When not in use, the tonometer can be stored in a position that does not interfere with examinations, while allowing quick setup during intraocular pressure measurement.

Designed exclusively for TAKAGI 4ZL/2ZL slit lamps. A matching plated finish is applied to maintain a unified appearance with the slit lamp. Installation requires the optional TB2 Tonometer Base.
