Comparing Refraction Data

One of the advantages of a digital refractor is the ability to quickly and easily compare different
refractions with the push of a button, enabling patients to see the difference between their old and new
prescriptions, or the difference between two possible prescriptions.
After completing a refraction, you can switch the measurements in the storage boxes and the current
measurements, as needed, enabling comparison of different prescriptions. Once you transfer the data
to the large active data field, the Phoroptor Head changes the lenses to reflect that data. This allows for
easy comparison.
The two methods to compare refraction are as follows: (Please refer to Figure IU-44.)
• Press the gray buttons at the top left of the Keypad to switch between different types of refraction
data, including Final (CC), Subjective, Unaided (SC), Auto Refractor (AR), and Lensmeter (LM).
• Touch the drop-down list at the top of the main refraction data area to select and compare
different types of refraction data, including Final (CC), Subjective, Unaided (SC), Auto Refractor
(AR), Lensmeter (LM), Mem 1, Mem 2, and Mem 3.
