3.4 Capturing
Faulty fixing of the sight, eyelid drooping, trichiasis,
corneal diseases, etc. may affect the measurement
result.
When the measurement image is unclear, select or
measure another image.
Be sure to touch the “New Patient” button on the
Capture screen of the personal computer to delete
the measurement data for the previous patient before
measuring a new patient. If new measurement is started
without deleting the previous data, the measurement
data for the previous patient may be included.
3.4.1 Patient's eye height adjustment
When moving the head and/or chin rest of the
instrument, pay attention to the position of the patient's
face, hands, and fingers. The patient may be injured
by the movement of the head or chin rest.
The chin rest paper is provided to keep the chin rest
clean. Use this paper for the chin rest as well as the
patient to use this instrument comfortably.
Peel off the top sheet of chin paper and clean the
forehead pad with a clean cloth before measuring
the next patient. Clean the forehead pad with a cloth
dampened with alcohol as needed.
1) Have the patient place their face on the chin rest (1).
Adjust the chin rest height so that the height of the
corner of the eye is aligned with the eye level mark (2).
Pressing the UP (4) and DOWN (5) buttons on the
membrane button panel moves the chin rest up and
down respectively.
2) When the patient's eye height is determined, lightly
push the patient's forehead against the forehead pad
(3) to secure the patient's position.
