Predicting Lens Tilt Using Optical Coherence Tomography and Partial Least Squares Regression Modelling

Misalignment of IOLs can cause severe loss of visual quality. Different types of misalignment are known. Tilt is one type of misalignment that is thought to play a negative role for the optical performance in eyes with IOL designs, especially, if they have aspheric, toric or multifocal optics. Due to the fact that tilt has an influence on visual quality, the prediction of the post-operative tilt could improve IOL power calculaton significantly especially for toric IOLs. the Aim of this study is to measure tilt with two modern OCT based devices and one Scheimpflug camera and to predict the post-operative tilt using partial least squares regression.
