ACCOMMODATION COMPENSATION SYSTEMS AND METHODS
First Claim
1. A method of obtaining a residual accommodation measurement of an eye of a patient, the method comprising:
- obtaining a first induced metric for the eye that corresponds to a first viewing condition;
obtaining a second induced metric for the eye that corresponds to a second viewing condition;
determining if a difference between the first induced metric and the second induced metric exceeds a threshold;
determining an accommodation characteristic of the eye if the difference between the first induced metric and the second induced metric does not exceed the threshold; and
determining the residual accommodation measurement of the eye based on the accommodation characteristic.

Abstract
Methods and systems for obtaining an ocular aberration measurement of an eye of a patient are provided. Exemplary techniques involve obtaining a first induced metric for the eye that corresponds to a first accommodation state of the eye, obtaining a second induced metric for the eye that corresponds to a second accommodation state of the eye, and determining a natural metric of the eye based on the first and second induced metrics. An induced metric may include a pupil size or a spherical aberration. Techniques can also include determining a target metric for the eye base on the natural metric, determining whether an actual metric of the eye meets the target metric, obtaining an ocular aberration measurement of the eye if the actual metric meets the target metric, and determining a treatment for the eye based on the ocular aberration measurement.

8. A method of determining a natural metric of an unaccommodated or minimally accommodated eye, the method comprising:
-
inputting a first induced metric for the eye that corresponds to a first accommodation state of the eye; inputting a second induced metric for the eye that corresponds to a second accommodation state of the eye; and determining the natural metric of the unaccommodated or minimally accommodated eye based on the first and second induced metrics and the first and second accommodation states of the eye. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
