IOLSTAT--a program for comprehensive intraocular lens equation comparison with statistical analysis.
A computer program that will simultaneously solve five of the major intraocular lens (IOL) equations predicting the primary implant power required for emmetropia or ametropia is presented. The program can, alternatively, predict the degree of ametropia given the power of an IOL. The resultant predictions are analyzed using weighted and unweighted statistics, predicting a mean and a standard deviation. The results are displayed in a table which lists the prediction and the percent deviation from the weighted mean for each equation. The program features automatic averaging of keratometer readings, ultrasound axial length corrections, and an algorithm for estimating postoperative anterior chamber depth.
