Align the Eye: Model 5010 and 5015
The Model 5010 and 5015 guides you with a green centering ring as you use the joystick to align the optics
head.
• Rotating the joystick right or left raises and lowers the optics head.
• Pushing the joystick left or right moves the optics head left or right.
• Pulling or pushing the joystick moves the optics head forward and backward.
Instruct the patient to look at the basket of the hot air balloon. Locate the right eye and use the joystick to
center the target within the patient’s pupil. Move in or out following the prompt cue at the top of the
display until “Focused” prompt appears. Then move (rotate) the joystick up and down, as well as right and
left in order to center the target within the patient’s pupil.
At this point, the target will turn green and automatically acquire a reading (Auto mode). If in Manual
Mode, there will be a “Press Joystick” prompt on the screen.
Aligning the eye, Model 5010 and 5015
Automatic or Manual Mode
In the automatic mode, the Acuitus 5010/5015 will refract the eye. After measurement, the result is
displayed. (See fig. page 10.) If you are using the manual mode, the Acuitus 5010/5015 will begin to take
multiple refractive measurements as soon as the eye is aligned. Press the button on the top of the joystick
when prompted in order to freeze the results and display them on the screen.
Clearing Results to Re-refract
The last refraction for one or both eyes remains in the instrument’s memory until another refraction is
initiated or the five-minute time-out limit is passed. There are two ways to clear refraction data from the
display immediately if you would like to re-refract an eye.
1. Reposition the optics head. If you have refracted both eyes, moving the optics head back to the first eye
will clear data for that eye and allow you to take another measurement. Results for the second eye will
remain on the display unless the optics head is moved to that eye a second time.
2. Print results. Pressing the Print button prints out the examination results, clears the patient’s data from
the refractor, and prepares the instrument for the next patient.
Turning off the power also erases all stored refraction data.
