The most critical practice for maintaining the Schiotz tonometer's functionality is daily cleaning. This is essential because the tonometer's measurement and accuracy can be significantly affected by debris, oils from the skin, and other contaminants that may accumulate on its contact surfaces. Cleaning the tonometer daily helps ensure that it remains free of any substances that could interfere with the readings, thereby promoting accurate intraocular pressure measurements.

While daily calibration, regular lubrication, and monthly inspections are important for overall maintenance and to ensure the device functions correctly, the immediate and necessary measure to protect the integrity of the tonometer’s measurement capabilities on a daily basis is cleaning. A clean tonometer not only helps in obtaining precise readings but also reduces the risk of infection transmission between patients.
