AI Technical Summary

Problems solved by technology

The resulting force can distort the shape of the cornea and reduce the accuracy of corneal measurements in at least some cases
Deformation of the cornea associated with placement of the patient interface can limit the accuracy of corneal measurements and alignment for corneal surgical procedures
Also, images obtained with prior laser systems configured to be coupled to the eye with a patient interface may in at least some cases be at least partially distorted, which may distort images from the prior laser surgery system from images such as corneal topography and tomography. Combinations of prior eye measurement systems such as imaging systems are less than ideal in at least some cases

Embodiment Construction

[0086] Methods and systems related to laser eye surgery are disclosed. In many embodiments, lasers are used to make precise incisions in the cornea, lens capsule, and / or lens nucleus. While specific reference is made to tissues for laser eye surgery, embodiments as described herein may be used in one or more of numerous ways in many surgical procedures and devices, such as orthopedic, robotic, and microscopic Corneal lamellar knife.

[0087] Embodiments as described herein are particularly well suited for treating tissue, such as in the case of surgical treatment of tissue. In many embodiments, the tissue includes optically transmissive tissue, such as tissue of the eye. Embodiments as described herein can be combined in many ways with one or more of the many known refractive surgery procedures such as cataract surgery, corneal incisions, including for example laser assisted in situ keratomileusis (hereinafter "LASIK"), All Laser LASIK, Femto LASIK, Orthokeratology, Astigma...

Abstract

The methods and apparatus are configured to measure the eye without the eye contacting the patient interface, and use these measurements to determine the alignment and placement of the incision when the patient interface contacts the eye. The pre-contact position of one or more structures of the eye may be used to determine a corresponding post-contact position of one or more optical structures of the eye when the patient interface has contacted the eye such that the laser incision is placed at a location that promotes normal vision of the eye . The incisions are positioned relative to the pre-contact optics of the eye, such as the astigmatic axis, the nodes of the eye, and the visual axis of the eye.

Description

[0001] cross reference [0002] This application claims priority to U.S. Provisional Application No. 61 / 813,613, filed April 18, 2013, and U.S. Provisional Application No. 61 / 873,071, filed September 3, 2013, entitled "Corneal topography measurement and alignment of corneal surgical procedures" ; the contents of which are incorporated herein by reference for all purposes. Full Paris Convention priority is therefore expressly reserved.
