e) Entering parameters for Clinical History Method
It is activated only when Double K SRK/T is selected as the formula.
1) Manually enter the corneal refractive power or radius of corneal curvature
before the surgery for correcting the refractive power in PreK1 and PreK2
(1). Change the unit indication according to the value entered.
2) Manually enter eye refractive power before refractive correction surgery in
PreRef (S,C)(2) and eye refractive power after refractive correction surgery
in PostRef (3).
3) When values are entered in PreK1, PreK2, PreRef (S,C), and PostRef
(S,C), the calculation starts automatically and the corneal refractive power
or radius of corneal curvature after the refractive power correction surgery
is displayed in PostK (4). However, it can also be entered manually. When
entered manually, the PreRef (S,C) and PostRef (S,C) cannot be entered.
4) Select a distance between the vertexes (V.D.) from the pull-down menu (5).
