The Riester Schiotz tonometer, meticulously crafted in Germany, is a time-tested and reliable instrument for measuring intraocular pressure (IOP). This mechanical indentation tonometer operates based on the principle of corneal indentation under a known weight. The degree of indentation, read from a scale, is then converted to IOP using conversion tables specific to the instrument.

Renowned for its accuracy and durability, the Riester Schiotz tonometer is a fundamental tool in ophthalmology for glaucoma screening, diagnosis, and monitoring. Its straightforward design and ease of use have made it a trusted instrument for decades. While newer tonometry methods exist, the Schiotz remains valuable, particularly in settings where advanced equipment may not be readily available or as a reliable backup. The German engineering ensures precision and longevity, making it a cost-effective and dependable solution for IOP measurement. Its portability also makes it suitable for use in various clinical settings and outreach programs.
