    Arms and Interventions

    Arm Intervention/Treatment
    Bilateral intraocular lens implantation.

    Outcome Measures

    Primary Outcome Measures

    1. Amplitude of accommodation on COAS and how it correlates with: spherical aberration on the COAS, pupil size at near as measured with COAS, spherical aberration on the topography, patient reported nead for spectacles for reading [one study visit]

    Secondary Outcome Measures

    1. Amplitude of accommodation on pushdown test - and how it compares to the COAS test results [one study visit]
