At which settings should the calibration of the Goldmann applanation tonometer be checked?

The correct calibration settings for the Goldmann applanation tonometer are indeed 0, 2, and 6. This device is designed to measure intraocular pressure (IOP) by flattening a specific area of the cornea. Regular calibration is essential to ensure accurate readings, as errors in IOP measurement can lead to misdiagnosis or improper management of glaucoma and other ocular conditions.

In the calibration process, specific pressure points act as benchmarks to verify the device's accuracy. The selected points—0, 2, and 6—are chosen because they represent a range that allows the technician to confirm that the tonometer is functioning correctly across different pressures that are clinically relevant. This ensures that readings taken during patient examinations will be reliable and valid.

This focus on appropriate calibration underscores the importance of routine maintenance and checks in ophthalmic instruments to maintain the integrity of patient care. Understanding the calibration points helps ensure that the tonometer delivers precise measurements, which is vital for effective monitoring and treatment strategies in ocular health.
