Methods and systems for obtaining an ocular aberration measurement of an eyeof a patient are provided. Exemplary techniques involve obtaining a first inducedmetric 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 accommodationstate of the eye, and determining a natural metric of the eye based on the firstand second induced metrics. An induced metric may include a pupil size or a sphericalaberration. Techniques can also include determining a target metric for theeye base on the natural metric, determining whether an actual metric of the eyemeets the target metric, obtaining an ocular aberration measurement of the eyeif the actual metric meets the target metric, and determining a treatment forthe eye based on the ocular aberration measurement.
