b) Corneal refractive power and radius of corneal curvature (K1/K2)
When keratometer measurement is completed, the measurement data is already
entered automatically and cannot be entered manually. (Refer to “3.4.3 e)
Selecting specific measurement data to be used for calculating IOL power.")
When measurement has not yet been performed, enter the data as follows.
(Fig. 1)
1) Touch the K1 input field (1) or the K2 input field (2) to activate it. The keypad
(3) appears. Touch the “Enter” key (4) to apply the data.
[Input range]
Corneal refractive power : 30.00 - 60.00D
Radius of corneal curvature : 5.00 - 11.00 mm
c) Target Ref.
(Fig. 1)
1) Touch the Target Ref. input field (1) to activate it. The keypad (2) appears.
Touch the “Enter” key (3) to apply the data.
[Input range] Angle : -30.00 – +10.00
The entered value is stored in the main unit, and is not cleared even when the
power is turned off.
d) Lens 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)
(3) corresponds to the lends (2) and (4), and the formula (5) (7) corresponds to
the lends (6) and (8). There are 2 ways to enter the values. One is to enter them
directly using the keypad, and the other is by selecting them from the IOL data list.
