The impact of dry eye disease on visual function and patient satisfaction: A cross-sectional study

Background: (DED) it is a prevalent ocular condition characterized by tear film instability and ocular surface inflammation, leading to symptoms such as dryness, irritation, and visual disturbances. These symptoms can significantly impair visual function and reduce patient quality of life.Aim: To evaluate the impact of Dry Eye Disease on visual function and patient satisfaction, and to investigate the associations between clinical signs, symptom severity, and quality-of-life measures in a cross-sectional cohort of 84 patients.Methods: A cross-sectional study was conducted from February 2024 to March 2025 involving 84 patients where in this Study Data collected included demographics, DED classification (Definite, Suspected, No DED), Ocular Surface Disease Index (OSDI) scores, Visual Function Questionnaire (VFQ-25) composite and subscale scores, Tear Film Break-Up Time (TBUT), Schirmer test results, and patient satisfaction with treatment additinally Statistical analyses included descriptive statistics, chi-square tests for categorical associations, and linear regression to assess predictors of visual function.Results: in this study we, the results were found ( Mean age was 52.3±10.4 years, DED Classification: 40.5% had definite DED, 21.4% suspected DED (signs only), 19.0% suspected DED (symptoms only), and 19.0% no DED in addition to OSDI Scores were Mean score 26.8±18.7; 33.3% mild, 31.0% moderate, 35.7% severe symptoms however Visual Function (VFQ-25) was Mean composite score 85.3±14.5 overall, 85.3±14.5 in DED group vs. 92.3±8.3 in no DED group, TBUT was Mean 4.7±3.5 seconds in DED vs. 10.0±2.4 seconds in no DED, Schirmer Test was Mean 4.1±3.7 mm in DED vs. 12.2±4.5 mm in no DED and in finally we concourse dry eye disease significantly impairs visual function and daily activities, with symptom severity strongly predicting reduced quality of life.
