Publication number: 20250228658Abstract: Particular embodiments disclosed herein provide an alignment guide for aligning a toric IOL during surgery. An image with a reference axis is obtained, such as from a digital microscope, and processed, to obtain a segmented image excluding portions of the image outside of a limbus of a patient's eye. The segmented image is processed, such as using an autoencoder, to label alignment marks on the IOL and possibly other features of the IOL. The label is processed, such as using a logistic regression model, to estimate an IOL axis of the IOL intersecting the alignment marks. An output image is generated from the image that has superimposed thereon guides to a surgeon, such as a line representing the IOL axis, a rotation direction indicator, and a number or other representation of a difference between the reference axis and the IOL axis.Type: ApplicationFiled: April 7, 2025Publication date: July 17, 2025Inventors: Vignesh Suresh, Lu Yin, Ramesh Sarangapani, Tobias Jura Rapoport
