System for characterizing cataract density

Abstract

An ophthalmic surgical system includes an item of ophthalmic surgical equipment and one or more computing devices. The one or more computing devices are configured to receive a three-dimensional image of an eye of a patient; process the three-dimensional image using a machine learning model to obtain a density map of a crystalline lens of the eye of the patient; and control the item of surgical equipment according to the density map. The item of surgical equipment may be a treatment laser or phaco-vit tool. Aspiration pressure of the phaco-vit tool may be controlled based on a position of a distal end of the phaco-vit tool and a corresponding density in the density map.
