d) Lends constants (A-constant/SF/ACD-constant/a0･a1･a2)
Enter various lends constants for IOL according to the formula. This
instrument is able to calculate up to 4 constants for 1 formula
simultaneously. The formula (1) corresponds to the lends (2) and (3), and
the formula (4) corresponds to the lends (5) and (6). There are 2 ways to
enter the values. One is to enter it directly by using “numerical” keys, and
the other is by selecting it from the IOL data list.
● Entering through keypad:
The lens constants a0, a1, and a2 in the HAIGIS optimized formula cannot
be entered directly using “numerical” keys. Refer to “Entering through IOL
data list” below.
