Abstract: Certain aspects of the present disclosure provide for in-situ intraocular lens (IOL) tilt determination and for providing information associated with the angle of IOL tilt intraoperatively. An example method includes imaging an IOL within a patient's eye via an ophthalmic imaging device, in-situ, after implantation of the IOL within the patient's eye; processing the image of the IOL within the patient's eye to determine an angle of tilt of the IOL; and outputting information associated with the angle of IOL tilt to a user interface.

Abstract: A multi-beam splitter enables superimposing overlay content onto an optical field of view of a microscope using a compact and flexible design that is cost-effective for many applications. The multi-beam splitter also enables capturing of the optical field of view without the overlay content.

Abstract: In certain embodiments, a system for tracking movement of an eye comprises a camera system, a computer system, and an output device. The camera system generates images of the eye. The computer system stores the images and at least one of the images as a reference image. The computer system also tracks movement of the eye within a tracking range by comparing a current image with the reference image, and by determining a movement of the eye from the comparison of the current image and the reference image. The tracking range has one or more alert points. The computer system also determines an orientation of the eye relative to at least one alert point of the tracking range. The output device outputs a range indicator that indicates the orientation of the eye relative to the at least one alert point of the tracking range.

Abstract: 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, 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. Tracking of features of the IOL may be performed across multiple images to predict the location of features not represented in a particular image.

Abstract: A system for controlling a medical device with a virtual foot pedal is disclosed herein. The system may include at least one medical device, a display screen coupled to the medical device, and a virtual foot pedal. The virtual foot pedal may be connected to the medical device and may be further operable to capture motion in a tracking area. A method for controlling a medical console is disclosed herein. The method may include displaying one or more icons disposed on a display screen disposed on the medical console. The method may further include initiating the virtual foot pedal to emit a tracking area, monitoring movement of a foot in the tracking area, and receiving a selectin of at least one icon based on movement of the foot.
