Claims
- 1. A system for treating an eye of a patient, the eye having a cornea and a pupil, the pupil having a center, the system comprising:
a laser producing a laser beam capable of ablating the cornea; delivery optics in an optical path from the laser; alignment optics aligned with the delivery optics for maintaining alignment between the laser and the pupil of the eye; and an input for designating at least one treatment center, the input operatively associated with the delivery optics, the treatment center offset laterally from the center of the pupil when the pupil of the eye is aligned with the alignment optics.
- 2. The system of claim 1, further comprising a controller operatively associated with the delivery optics, the controller directing the optics to deflect the beam laterally so as to effect a treatment profile centered about the designated treatment center.
- 3. The system of claim 1, wherein the controller comprises a library of alternative refractive therapies, the alternative therapies individually selectable for ablating the cornea about the designated treatment center, the library including a myopic treatment profile, a hyperopic treatment profile, and a cylindrical astigmatism treatment profile.
- 4. The system of claim 1, further comprising:
a controller, the controller effecting a refractive correction of the eye by selectively directing the laser with the delivery optics, the refractive correction comprising a regular refractive correction when centered at the center of the pupil, the controller centering the refractive correction at the treatment center so as to mitigate an irregular refractive error of the eye.
- 5. A system for treating an eye of a patient, the eye having a cornea, the system comprising:
a laser producing a laser beam capable of ablating the cornea; delivery optics in an optical path from the laser; alignment optics aligned with the delivery optics for maintaining alignment between the laser and a first center of the eye; and an input for designating at least one treatment center, the input operatively associated with the delivery optics, the treatment center offset laterally from the first center of the eye when the first center of the eye is aligned with the alignment optics.
- 6. The system of claim 5, further comprising a controller operatively associated with the delivery optics, the controller directing the optics to deflect the beam laterally so as to effect a treatment profile centered about the designated treatment center.
- 7. The system of claim 5, wherein the controller comprises a library of alternative refractive therapies, the alternative therapies individually selectable for ablating the cornea about the designated treatment center, the library including a myopic treatment profile, a hyperopic treatment profile, and a cylindrical astigmatism treatment profile.
