The Luxvision TN-180B mounts easily onto the slit lamp and folds down from the top of the slit lamp, allowing you to accurately measure intraocular pressure. The Luxvision TN-180B mounts easily onto the slit lamp and folds down from the top of the slit lamp, allowing you to accurately measure intraocular pressure. And, when not in use, the TN-180B does not interfere with the operation of the slit lamp. This tonometer is a Goldmann-type device, widely recognized as the most common and straightforward method for assessing IOP. The precision of the TN-180B makes it an ideal choice for any practice.
The gold standard
Goldmann applanation tonometry is the most widely used tonometer in clinical practice and remains the “gold standard” for tonometry worldwide. It was developed in the 1950s and is based on the Imbert-Fick law, which states that the pressure in a sphere filled with liquid and surrounded by an infinitely thin and flexible membrane is measured by the counter-pressure required to flatten said membrane into a plane.

Unique Design
The unique foldable design of the TN-180B was carefully developed to deliver precision and ease of use. By selecting the TN-150B, you can rely on accurate readings regardless of scleral rigidity, while also obtaining a direct and precise numerical value. Pressure measurement can also be calibrated, ensuring reliable readings and extended stability over time.

When used with a slit lamp, it allows examination of the eyes and measurement of intraocular pressure. It provides a direct reading of intraocular pressure, without the need to consult a conversion table. The measured ocular pressure is not affected by corneal rigidity.
