Positioning The Patient; Refraction: Model 5000 - Zeiss Acuitus 5000 Manual Del Usuario

Positioning the Patient

Seat the patient comfortably. Raise or lower the power table until the Acuitus forehead
rest is lined up with the patient's forehead. Ask the patient to place his or her forehead
firmly and comfortably against the forehead rest while the chin rests on the chin rest.
Raise or lower the chin rest until the patient's eye is at the same level as the eye position
marker on the forehead rest
Important: For reasons of hygiene, be sure to wipe the forehead and chin rest with
an alcohol swap after each patient.

Taking refractive measurements with the Acuitus 5000 is easy.
1. Press the button under the icon to choose plus or minus cylinder. Your selection will
appear in bold type.
2. Seat the patient at the instrument as described above. Instruct the patient to look at the
basket of the hot air balloon.
3. Align the eye in the eye monitor as described on page 7.
4. As soon as the eye is aligned, the Acuitus will automatically begin to take multiple
refractive measurements. Press the button on the top of the joystick to freeze the
results.
5. Repeat the process for the other eye. Results for both eyes are shown on the same
screen.
6. Press the Print button.
Note: The Acuitus is designed to operate in most lighting conditions. Subdued lighting is
recommended for difficult patients or those with very small pupils. The use of mydriatics
may make refraction possible with patients who cannot be measured otherwise because of
very small pupils or cloudy media.
