PREDICTED VERSUS MEASURED POSTERIOR CORNEAL ASTIGMATISM AND THE IMPACT ON TORIC IOL POWER CALCULATIONS IN STANDARD CATARACT SURGERY

A majority of comparative studies using the Barrett toric IOL calculator are suggesting that the use of predicted and measured PCA does not impact clinical outcomes. One report showed benefits of utilizing predicted PCA in refractive outcomes of eyes with WTR and ATR astigmatism. Two reports supported the use of measured PCA in eyes with high PCA of more than 0.8D and a whole group analysis but not in the subgroup analysis of WTR, ATR and oblique eyes.
