DOI: https://doi.org/Background: Diabetes mellitus is associated with ocular surface abnormalities that can affect outcomes of cataract surgery. This study compares preoperative ocular surface tests between 50 diabetic and 50 non-diabetic patients.
Methods: Measures included Schirmer test (mm), tear break-up time (TBUT) and Ocular Surface Disease Index (OSDI). Independent t-tests, Mann–Whitney U, and chi-square tests were used.
Results: Diabetics had significantly lower Schirmer, shorter TBUT, higher OSDI (all p < 0.01). Dry-eye prevalence was 76% in diabetics versus 8% in controls.
Conclusion: Diabetic patients exhibited significantly worse ocular surface parameters preoperatively, supporting careful assessment and optimization before cataract surgery.
