Abstract: The disclosure provides a system that may: receive data associated with multiple locations associated with a cornea of an eye; adjust at least one lens, based at least on diameter information of the data associated with at least one of the multiple locations, to set a diameter of a laser beam; and for each location of the multiple locations: determine if the eye has changed from a first position to a second position; if the eye has not changed from the first position to the second position, adjust, based at least on the location, at least one mirror; if the eye has changed from the first position to the second position, adjust, based at least on the location and based at least on the second position, the at least one mirror; produce the laser beam; and direct the laser beam to the location for a period of time.

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.

Abstract: In certain embodiments, a patient interface apparatus for ophthalmic surgery comprises an annular member and an evacuation conduit. The annular member has an outer side, an inner side, a distal side, and a proximal side. The inner side defines an opening that allows for a laser beam to reach a treatment region of an eye free from reflection or refraction. The proximal side has a contact surface shaped to affix to a surface of the eye, and a groove that defines a suction chamber with the surface of the eye. The evacuation conduit is capable of fluid communication with the suction chamber, and conducts fluid away from the suction chamber to affix the contact surface to the surface of the eye.

Abstract: An eye model comprises a sclera simulation which is made of a bright plastic material and a pattern which contrasts in color with the sclera simulation, the pattern simulating an eye pupil and/or an iris structure. The eye model is used to calibrate an eye tracking system.

Abstract: A surgical system corrects a surgical parameter based on a nomogram specific for a refractive laser surgery system to provide a nomogram-based corrected surgical parameter; stores the surgical parameter and the nomogram-based corrected surgical parameter as data for a patient or for one or both eyes of the patient; and compares the surgical parameter and nomogram-based corrected surgical parameter to generate a graphical representation of the surgical parameter, a target outcome parameter associated with the surgical parameter, or both, and the nomogram-based corrected surgical parameter, to generate a warning based on a comparison of the nomogram-based corrected surgical parameter to the surgical parameter or an absolute value, or both.

Abstract: The present disclosure provides a refractive laser surgery system including a processor having access to memory media storing instructions or sets of instructions executable by the processor to identify a surgical parameter; correct the surgical parameter based on a nomogram specific for the refractive laser surgery system to provide a nomogram-based corrected surgical parameter; store the surgical parameter and the nomogram-based corrected surgical parameter in the memory media as data for a patient or for one or both eyes of the patient; and compare the surgical parameter and nomogram-based corrected surgical parameter to generate a graphical representation of the surgical parameter, a target outcome parameter associated with the surgical parameter, or both, and the nomogram-based corrected surgical parameter, to generate a warning based on a comparison of the nomogram-based corrected surgical parameter to the surgical parameter or an absolute value, or both. Methods of using the system are also provided.
