Determinants of Posterior Corneal Astigmatism Orientation With Emphasis on High Against-The-Rule Anterior Astigmatism: Insights From 17,860 Eyes.
PURPOSE To identify determinants of posterior corneal astigmatism (PCA) orientation, including anterior corneal astigmatism (ACA) orientation and magnitude. METHODS In this retropective cross-sectional observational study, anonymized swept-source optical coherence tomography biometry measurements (IOLMaster 700) were...
