Kane Formula

The Kane formula is an optical theoretical formula for IOL power calculation that optimizes its performance by means of regression and artificial intelligence components. Variables used in the formula are axial length, keratometry, anterior chamber depth, lens thickness (optional), central corneal thickness (optional), and patient biological sex. A summary is given on the available publications showing the Kane formula to be one of the best among the newer IOL power calculation formulas. The Kane keratoconus formula is designed for keratoconic eyes adjusting the IOL power based on the correct anterior/posterior corneal ratio in these eyes. The Kane toric formula calculates the toric IOL power using theoretical optics, regression, and artificial intelligence.
