About

The objective of this observational study was to understand the healing of corneal incision after cataract surgery in diabetic patients and its influencing factors. The main questions it aims to answer are:

Is corneal incision healing worse in diabetic patients after cataract surgery than in non-diabetic patients? What are the factors affecting corneal incision healing after cataract surgery in diabetic patients?

The results of anterior segment optical coherence tomography before and after cataract surgery in cataract patients with or without diabetes will be collected and analyzed.
