Though it is generally agreed that accurate identification of the magnitude and axis of astigmatism is essential in order to choose the right toric power and correctly position it, there is no strong consensus about which measurement is best to base magnitude and axis decisions. Results from a recent clinical survey support this trend.
Alcon recently launched Toric Pro, a new app that gives cataract surgeons a number of tools in a single app intended to improve their knowledge on toric IOL procedures for treating astigmatism at the time of surgery.
The ratio of the anterior to posterior corneal curvature is not constant for astigmatism. By factoring in the contribution of the posterior cornea based on population data, the Baylor toric IOL nomogram can improve surgical outcomes following toric IOL implantation.
