Study 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.

Inclusion Criteria: * Senile cataract patients, with or without macular disease, the impact of cataract on vision has affected the daily life of patients. Exclusion Criteria: * Glasses can obviously improve eyesight * In addition to macular disease, combined with other eye diseases that seriously affect vision, resulting in no significant improvement in postoperative vision * Complicated cataract surgery due to trauma and other reasons * Combined with other eye diseases not suitable for intraocular lens implantation * Patients with systemic diseases who cannot tolerate surgery

Primary outcome measure(s)

The UCVA was measured by the same optometrist at each visit
Best Corrected Visual Acuity — 1 month postoperatively
The BCVA was measured by the same optometrist at each visit
Macular optical coherence tomography — 1 month postoperatively
Macular oct was measured by the same doctor at each visit
