Refraction: Model 5010 and 5015
To take a refractive measurement with the Acuitus 5010 and 5015 make your choices on
the refraction screen and follow the steps below. Your choices will appear in bold type on
the screen.
To turn an option off completely — if you do not want to perform keratometry, for
example — press the button until all of the choices appear in gray, not bold, type.
1. Select
Automatic
or
Manual
operation.
2. Press the button under the icon to select plus or minus cylinder.
3. Make sure refraction (
Ref
) is selected, not contact lens measurement (
CL
).
4. Press the button to select
CK
(central keratometry), both
CK
and
PK
(peripheral
keratometry), or neither. Keratometry may be done as part of a refractive examination
or separately. (See page 13 and 14 for more detailed instructions on keratometry.)
5. Seat the patient at the instrument as described on page 6.
6. Align the eye in the eye monitor by the method described on page 11. In the automatic
mode, the Acuitus 5010 and 5015 will refract the eye and display the results as soon as
the eye is aligned. If you have chosen the manual mode, press the button on the top of the
joystick.
7. Move the optics head to the second eye and repeat the process.
8. Press the Print button if in Manual Mode.
