[0005] Despite Advances in Imaging Systems, Performing Eye Surgery Remains Challenging
In particular, surgeons viewing stereomicroscope images may have difficulty discerning precisely how deep a surgical tool is inserted into the eye and its proximity to specific tissues, such as the retina

Abstract

An ophthalmic surgical system is disclosed that includes an imaging unit configured to generate a fundus image of an eye, and a depth imaging system configured to generate a depth-resolved image of the eye. The system also includes a tracking system communicatively coupled to the imaging unit and the depth imaging system, the tracking system including a processor and memory configured to: analyze the fundus image to determine the location of the distal tip of the surgical instrument in the fundus image, analyzing the depth-resolved image produced by the depth imaging system to determine the distance between the distal tip of the surgical instrument and the the distance between the retinas of the eye, a visual indicator is generated to cover a portion of the fundus image, the visual indicator indicates the determined distance between the distal tip and the retina, the visual indicator is modified in real time Changes in the position of the distal tip within the fundus image are tracked, and the visual indicator is modified to indicate changes in the distance between the distal tip of the surgical instrument and the retina in real time.

Description

technical field [0001] The present disclosure relates generally to surgery, and more particularly to ophthalmic surgery visualization systems and methods. Background technique [0002] Many microsurgical procedures require precise cutting and / or removal of body tissue. For example, certain ophthalmic surgeries require cutting and / or removing the vitreous humor, a clear, jelly-like material that fills the back segment of the eye. The vitreous humor, or vitreous, is composed of microscopic fibrils that are usually attached to the retina. Cutting and removing the vitreous must be done with extreme care to avoid pulling on the retina, detaching the retina from the choroid, tearing the retina, or in the worst case cutting and removing the retina itself. Delicate procedures such as mobile tissue management (eg, cutting and removing the vitreous near a detached portion of the retina or a retinal tear), vitreous base dissection, and cutting and removing membranes are particularly ...
