Elizabeth Yeu, MD Comparison of Toric IOL Results between Multicolor LED Total Corneal Analysis versus Nomogram-Adjusted Keratometry

Elizabeth Yeu, MD Comparison of Toric IOL Results between Multicolor LED Total Corneal Analysis versus Nomogram-Adjusted Keratometry:

Nomogram adjustment methods may suffer from inaccuracies by not taking into account or by assuming a fixed location of the steep meridian of the posterior corneal astigmatism. Directly measuring posterior corneal astigmatism with Cassini Total Corneal Astigmatism (TCA) can provide superior results as compared with nomogram adjustment methods.
