Abstract
An ophthalmic laser surgical system for treating an eye includes a laser device, one or more cameras, and a computer. The eye has anatomical features, including the cornea with the anterior corneal surface. The laser device directs a laser beam towards the eye. A camera generates images of the anatomical features, including the anterior corneal surface. The computer facilitates docking a patient interface onto the eye by accessing eye information describing the eye. The eye information comprises an eye model describing the anatomical features. The computer determines from the eye model the predicted corneal surface position when the eye is aligned to dock the patient interface onto the eye. The computer detects from the images the actual corneal surface position prior to docking the patient interface onto the eye, and compares the predicted corneal surface position with the actual corneal surface position to detect misalignment.
