A method of laser eye surgery including linking retinal vessel architecture to corneal topography. This enables registration of the steep axis of the cornea in order to orient a toric intraocular lens, and/or to place astigmatic keratotomy incisions. First, a detailed pre-operative retinal image of the vasculature of the retina is obtained. In addition, a pre-operative image of the topography of the eye is obtained. The retinal image is then correlated or superimposed on the topography image to provide a reference. After the patient lies down under the laser eye surgery system, and during the surgery, the retinal vasculature is monitored which provides a reference to the surgery system about the topography of the eye. This process enables registration of the steep axis of the cornea in order to orient a toric intraocular lens and/or to place astigmatic keratotomy incisions.

Retinal imaging for reference during laser eye surgery

A system and method for measuring a characteristic of an eye of a subject receive data pertaining to the subject; assign the subject to an assigned age category based on the data pertaining to the subject; adjust a brightness level of a fixation target according to the assigned age category for the subject; provide the fixation target for a subject to view; and objectively measure at least one characteristic of the eye of the subject while the subject views the fixation target at the adjusted brightness level.
