Abstract
Methods and systems for treating presbyopia involve ablating a corneal surface of a first eye of a patient to enhance vision of near objects through a central zone of the first eye and ablating a second eye of the patient to enhance vision of near objects through a peripheral zone of the second eye. The optical power of the first eye is increased in the central zone, while the optical power of the second eye is increased in the peripheral zone. In the first eye, a peripheral zone is used primarily for distance vision. In the second eye, a central zone is used primarily for distance vision. Systems include a laser device and a processor for directing the laser device to ablate the two eyes of the patient.
