A laser surgery system having a computer control system coupled to a laser subsystem and a patient seat. The control system is coupled to the laser through a laser alignment system. The control system can be coupled to the patient seat through a patient alignment system. The control system sends a nominal position signal to move the patient seat, laser subsystem, or both so that the patient's first eye is moved into substantial alignment with the laser beam axis. The control system can send a second nominal signal to move the patient's second eye into substantial alignment with the laser beam axis. The control system can optionally comprise both an operator display and an assistant display. The assistant display provides real-time information to an assistant positioned at an assistant station adjacent the patient seat. The control system can be programmed to display edit fields with different colors to provide an obvious indication of the refractive information of the eye. The control system can comprise an operator input for providing a pre-determined secondary ablative treatment. If it is determined that the first ablative treatment did not completely remove the epithelial layer from a target region, the operator actuates the operator input to deliver the secondary ablative treatment.

What is claimed is: 1. A laser refractive system comprising: a laser comprising laser delivery optics, the laser produces a laser beam having a longitudinal axis; a patient seat contoured to support a patient in a patient position so that first and second eyes of the patient are near first and second nominal optical axes, respectively; and a patient alignment system coupling the seat to the laser, the alignment system moving at least one of the patient seat or the laser delivery optics in response to a nominal position signal so that the laser beam longitudinal axis is substantially aligned with the first nominal optical axis. 2. A laser refractive system as recited in claim 1 wherein the alignment system is configured to automatically move at least one of the patient seat and the laser delivery optics to a second nominal position in response to a second nominal position signal so that the laser beam longitudinal axis is substantially aligned with the second nominal optical axis. 3. A laser refractive system as recited in claim 1 wherein the patient seat comprises an adjustable vacuum pillow that is adjustably configured to conform to patient's head, wherein the adjustable vacuum pillow is coupled to a vacuum source with a tubing. 4. A system as recited in claim 1, wherein: the patient seat is movable along at least X and Y horizontal directions; and the alignment system includes a control system configured to automatically position the patient seat at the first nominal position in the X and Y directions. 5. A laser refractive system as recited in claim 1 wherein the patient seat comprises an adjustable vacuum pillow that is adjustably configured to conform to patient's head, wherein the adjustable vacuum pillow is coupled to a vacuum source with a tubing. 6. A system as recited in claim 1, further comprising a computer program having a tangible medium and computer-readable code, wherein the control system uses the computer program to automatically align the patients second eye with the laser beam longitudinal axis. 7. A system as recited in claim 1, wherein the first nominal position is substantially near a center of the X and Y horizontal directions. 8. A system as recited in claim 7 wherein the patient seat is movable along the X, Y, and Z directions, wherein the control system is configured to automatically position the seat at a nominal position of the X, Y, and Z directions. 9. A system as recited in claim 1, the alignment system further comprising a fine adjustment mechanism for aligning the laser beam with the patient's first eye, wherein the fine adjustment mechanism moves the patient seat or a laser delivery optics. 10. A system as recited in claim 9, wherein the fine adjustment mechanism comprises an activating motor, wherein the activating motor is coupled to the patient seat and the control system such that the activating motor moves the patient seat in response to a signal from the control system. 11. A system as recited in claim 3, wherein the activating motor moves the patient seat in response to the signal that is generated from manual actuation of an input device. 12. A system as recited in claim 9, wherein the fine adjustment mechanism comprises an activating motor, wherein the activating motor is coupled to the laser delivery optics and the control system, such that the activating motor moves the laser delivery optics in response to a signal from a control system. 13. A system as recited in claim 12, wherein the activating moves the laser delivery optics in response to a signal that is generated from manual actuation of an input device. 14. A system as recited in claim 9, wherein the alignment system further comprises a gross adjustment mechanism that is independent of the fine adjustment mechanism, wherein the gross adjustment mechanism substantially aligns the first nominal optical axis with the laser beam longitudinal axis by moving the patient seat. 15. A system as recited in claim 14, wherein the gross adjustment mechanism comprises an activating motor, such that the activating motor moves the patient seat in response to the nominal position signal from the control system. 16. A system as recited in claim 15, wherein the activating motor moves the seat in response to the nominal position signal that is generated from manual actuation of an input device. 17. A system as recited in claim 14, wherein the control system actuates the gross adjustment mechanism, the fine adjustment mechanism, or both, to automatically substantially align a second eye of the patient with the laser beam longitudinal axis. 18. A system as recited in claim 17, wherein the control system substantially aligns the second eye of the patient with the laser beam longitudinal axis after the first eye has been treated with the laser. 19. A system as recited in claim 18, wherein the control system substantially aligns the second eye with the laser axis in response to an input into the control system.
