Toric Intraocular Lens Calculation Considering Anterior Surgically Induced Astigmatism and Posterior Corneal Astigmatism

PURPOSE: ). METHODS: calculation approaches: (A) considering only significant centroids after stratification, (B) all centroids after stratification and (C) a single centroid without stratification. RESULTS: addition to PCA estimation only reduced the centroid for oblique preoperative astigmatism. CONCLUSIONS: derived from the anterior corneal surface should not be combined with PCA estimation for IOL power calculations.
