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.

Inclusion Criteria:

Patients who experience blurred vision and painless visual acuity decline, and are diagnosed with cataract (with or without diabetes) through reliable intraocular pressure, visual acuity and slit lamp examinations, and for whom phacoemulsification of cataract can be considered.

Exclusion Criteria:

• Use multiple eye drops before surgery.
• Complicated by other eye diseases that affect corneal healing, such as keratitis, uveitis, glaucoma, etc.
• Moderate to severe dry eye.
• History of eye surgery.
• Moderate to severe dry eye.
• Grade 5 nuclear cataract.
• Severe systemic diseases (such as chronic renal failure requiring dialysis, severe neurological diseases, immune diseases), pregnancy or lactation.

Patients who were initially diagnosed with cataract and treated with phacoemulsification and intraocular lens implantation at Zhongnan Hospital of Wuhan University from April 1, 2024 to December 31, 2024.
