Imaging-based guidance system for ophthalmic docking using a location-orientation analysis

摘要

An imaging-guided docking system can separate the tilt and location of an imaged ophthalmic target and present them in an intuitive manner for an ophthalmic surgeon. The docking system can include an ophthalmic imaging system to image a portion of an eye of a patient, an image processor to determine a location and an orientation of the imaged portion of the eye, and a guidance system, coupled to the ophthalmic imaging system, to guide an ophthalmic docking based on the determined location and orientation. In some implementations, the imaging system images an internal eye-structure to determine its orientation and a video-imaging system video-images a frontal eye-structure to determine a location of the frontal eye-structure. The determined orientation and location can be displayed for the surgeon. The alignment of ophthalmic procedures can also be assisted with this imaging capability, e.g. the placement and centration of IOLs into the lens capsule.
