Image alignment in ophthalmic refractive surgery systems for refractive treatment of eye involves aligning two images of eye having spatial relationship, for performing refractive treatment

摘要

Diagnostic measurement of patient's eye (12) is done. An image having an iris image (120) of the patient's eye is obtained. A spatial relationship between the image and the diagnostic measurement is determined. A refractive treatment is developed based on the diagnostic measurement. Another image of patient's eye is aligned to obtain spatial relationship with the previous image for performing refractive treatment. Independent claims are also included for the following: (a) A system for aligning a refractive correction instrument with a patient's eye; (b) Method for providing a course of refractive treatment; (c) Method of aligning a refractive correction instruments with a patient's eye; (d) System for aligning refractive diagnostic and treatment data; (e) Method of aligning refractive tools; (f) Method for eye alignment and characterization; (g) System for alignment and photo refractive treatment of eye; (h) Laser system
