Patent ID: 8398238

Claim:
An ophthalmic docking system, comprising: an ophthalmic imaging system, comprising an optical coherence tomographic imaging system, configured to image a portion of an eye of a patient during a docking of a patient interface to the eye, and an image processor configured to determine a location and an orientation of the imaged portion of the eye by analyzing the image; and a guidance system, coupled to the ophthalmic imaging system, configured to guide the docking based on the determined location and orientation before the patient interface is docked to the eye, wherein: the imaged portion of the eye comprises an imaged portion of a lens of the eye; and the image processor is configured to perform an image recognition process to recognize a scan-image of an anterior capsular layer of the lens and a scan-image of a posterior capsular layer of the lens in the image; and wherein: the image processor is configured to determine an anterior maximum depth and an anterior minimum depth of the anterior capsular layer and a posterior maximum depth and a posterior minimum depth of the posterior capsular layer along a scanning variable, and to determine the location and the orientation of the lens from the anterior maximum depth, the anterior minimum depth, the posterior maximum depth, and posterior minimum depth.
