Abstract
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.
