Study Details

Study Description

Brief Summary

The purpose of this study is to collect the macular OCT images and preoperative and postoperative visual acuity of cataract patients who had been operated in the eye center of the Second Affiliated Hospital of Zhejiang University Medical College, and to train a model that can relatively accurately predict the postoperative visual acuity of patients by deep learing.

    Outcome Measures

    Primary Outcome Measures

    1. Uncorrected distance visual acuity [1 month postoperatively]

      The UCVA was measured by the same optometrist at each visit

    2. Best Corrected Visual Acuity [1 month postoperatively]

      The BCVA was measured by the same optometrist at each visit

    3. Macular optical coherence tomography [1 month postoperatively]

      Macular oct was measured by the same doctor at each visit
