• Ensure that the patient's eyelashes or eyelid are not in the applanation area and the
patient's eye is not watery.
These factors cause measurement errors or decrease the accuracy of measurements.
If the patient's eyelashes or eyelid are within the applanation area, lift the patient's lid, paying attention not
to press against the eyeball.
If the eye is watery, have the patient blink his or her eyes or wipe tears.
