My formula uses the Universal II, which is a method of predicting IOL power to work out where the lens is and uses that to calculate what is the effect of the cylinder power at the cornea. The toric calculator by Barrett is based on his well proven Universal II formula. a. Dynamic calculation of the lens position for cylinder power transformation to the corneal plane as well as consideration of the anterior and the posterior corneal curvature for cylinder power and axis calculation. b. Considering the thickness and shape of the lens as well, which provides a more sophisticated way of predicting and translating the cylinder power, he said. c. The formula is able to predict posterior corneal curvature without actually measuring it.
