Abstract
A system for positioning an eye for laser surgery includes a first and a second line generator positioned, respectively, to emit a first line and a second line orthogonal to the first line, the line generators positioned in a predetermined relation to a laser surgical system. A position of the eye is adjustable along an axis that is substantially perpendicular to the lines to achieve a positioning wherein the lines form a cross. The location of the cross is a preferred position for the eye relative to the laser surgical system for the laser surgery. The method of the present invention includes generating the orthogonal lines of radiation and adjusting a position of an eye to be along an axis substantially perpendicular to the lines to form a cross on a cornea of the eye in a plane.

A system for relatively positioning an eye and a surgical system for laser surgery comprising:
- a first and a second line generator positioned, respectively, to emit a first line and a second line orthogonal to the first line, and further positioned in a predetermined relation to a laser surgical system;
- and
- means for adjusting a relative position of the first and the second line generators relative to the eye to achieve a preferred position for laser surgery.
A method for positioning an eye for laser surgery comprising the steps of:
- generating a first and a second line of radiation, the first line substantially orthogonal to the second line;
- directing the first and the second lines to a position having a predetermined relation to a laser surgical system;
- and
- adjusting the position of the first and the second lines relative to an eye to achieve a preferred position of the eye relative to the laser surgical system for laser surgery.
