Method and device for ocular alignment and coupling of ocular structures
First Claim
1. A system for defining a reference axis of a patient'"'"'s eye in an external coordinate system, comprising:
- an eye guide adapted to be coupled to the patient'"'"'s eye;
a light source for directing a light beam on a reflective surface associated with the patient'"'"'s eye;
an imaging system for recording an image of a limbus of the patient'"'"'s eye and an image formed by a reflection of the light beam on the reflective surface; and
a guide-alignment assembly configured to adjust the eye guide until a position of the reflection is coincident with a center of the limbus.

Abstract
Embodiments provide method and systems for determining or measuring objective eye alignment in an external-coordinate system so as to define a reference axis. Additional embodiments provide a method and system of aligning an objectively determined reference axis of the eye in a selected relationship to a therapeutic axis of an ophthalmic therapeutic apparatus and/or a diagnostic axis of an ophthalmic diagnostic apparatus. Embodiments provide a method and system for planning an ophthalmic treatment procedure based on objective eye alignment in an external-coordinate system so as to define a reference axis of an eye to be treated. The reference axis may be used to position a therapeutic energy component, for example, an orthovoltage X-ray treatment device, e.g., positioned to provide treatment to tissue on the retina, such as the macula.
