A fiducial is generated on an internal anatomical structure of the eye of a patient with a surgical laser. A toric artificial intraocular lens (IOL) is positioned so that a marker of the toric IOL is in a predetermined positional relationship relative to the fiducial. This positioning aligns the toric IOL with the astigmatic or other axis of the eye. The toric IOL is then implanted in the eye of the patient with high accuracy.

Disclosed is an ophthalmological treatment apparatus for modifying a shape of a corneal surface of a human eye. The apparatus includes a surgical laser device for implementing tissue cuts. The apparatus further includes a computerized control device in operative coupling with the surgical laser device, the control device being designed to control the laser device to implement tissue cuts according to a cut geometry with a primary tissue cut and a secondary tissue cut, wherein the primary tissue cut is a relief cut and extends into the depth of the conical eye tissue, and wherein the secondary tissue cut lies within the conical eye tissue, such that the secondary tissue cut adds to the relieving effect of the primary tissue cut.

Generation of treatment recommendations for topographic-based excimer laser surgical procedures is described that includes generating accurate cylinder compensation and spherical compensation values that are adjusted to compensate for unique characteristics of topographic-based excimer laser surgical systems. Generating treatment recommendations generally includes determining a topographic vector, a posterior astigmatism vector and an anterior astigmatism vector, and generating an internal astigmatism vector using the topographic vector, the posterior astigmatism vector, the anterior astigmatism vector, and a manifest astigmatism vector. In embodiments, the cylinder compensation is generated using multiple vectors while subtracting the internal astigmatism vector and the posterior astigmatism vector which remain in the eye after treatment, and the spherical compensation is generated using an initial spherical compensation modified by addback modifiers and a regression analysis nomogram. In procedures where the corneal epithelium is removed, an epithelial refractive vector is determined from an epithelial thickness/topography map and added to the other vectors.
