Purpose

To compare the changes of pupil parameters and visual quality after cataract surgery and explore their potential correlations.

Methods

This retrospective cohort study analyzed clinical data of Han Chinese patients who received cataract surgery from June 2016 to October 2016.

n = 110 eyes

AUC of 0.71

Results

AUC of 0.71

this indicates the ability to predict poor vision from pupil size in dim light

n = 110 eyes

More results

Under both photopic and mesopic conditions, pupil diameter and pupil shift at 1d and 1mo after surgery were significantly lower than baseline levels.

Corneal aberrations decreased postoperatively.

More results

Photopic and mesopic modulation transfer function derived from higher-order (higher-order) aberrations increased significantly from postoperative day 1 to postoperative month 1.

Conclusion · 1 of 2

Pupil parameters and visual quality alter significantly after cataract surgery, and moderate correlations exist between pupil diameter and visual quality at each time point.

Conclusion · 2 of 2

Preoperative pupil diameter is correlated with 1-month postoperative visual quality.
