Intraocular Lens Power Calculation
But it did not work in extremely long or short eyes. Thus, the formula needed to be adjusted for the axial length to be accurately factored. The second generation regression formula, the SRK II, was developed by adding a C-value to the original SRK formula: P= A - 2.5L - 0.9K + C. If the axial length is 10 to 20 mm, the C value is 3.
