1. A method implemented in an ophthalmic measurement and laser surgery system for measuring a patient's eye, the method comprising:
by a laser source, producing a pulsed laser beam;
by a controller, operating a corneal topography determining subsystem of the ophthalmic measurement and laser surgery system to obtain corneal surface information of the eye;
by the controller, operating an axis determining subsystem of the ophthalmic measurement and laser surgery system to identify one or more ophthalmic axes of the eye;
by the controller, operating an optical coherence tomographer (OCT) of the ophthalmic measurement and laser surgery system to sequentially scan the eye in a plurality of OCT scan patterns, the plurality of scan patterns configured to determine an axial length of the eye;
by the controller, operating a refractive index determining subsystem of the ophthalmic measurement and laser surgery system to determine an index of refraction of one or more ophthalmic tissues of the eye; and
by the controller, modifying structural information of at least one of the corneal surface information, ophthalmic axis information, and axial length based on the determined index of refraction of the one or more ophthalmic tissues of the patient's eye.
