How often should the calibration of the applanation tonometer be checked?

1. Monthly

2. Every 6 months

3. Every 2 months

4. Annually

The correct answer is: Every 2 months

The calibration of an applanation tonometer should ideally be checked every 2 months to ensure accurate intraocular pressure readings. Regular calibration is crucial because even slight deviations in measurement can lead to misdiagnosis or inappropriate management of glaucoma and other ocular conditions. Given the dynamic nature of equipment used in clinical settings, checking the calibration bi-monthly allows for timely identification of potential discrepancies, which is essential for maintaining high standards of patient care and ensuring that the tonometer provides reliable results during glaucoma assessments or routine examinations. Other intervals, while may seem reasonable, do not address the need for more frequent validation, particularly in a clinical environment where consistent and precise measurements are vital.
