The Correlation of Quality of Life Impact of Refractive Correction Score with Visual Disturbances and Contrast Sensitivity in Spectacle Wearers: A Preliminary Study

ABSTRACT

@#Introduction: This study aimed to evaluate the correlation between Quality of Life Impact of Refractive Correction (QIRC) score with visual disturbances and contrast sensitivity in spectacle wearers. Methods: A total of 21 spectacle-corrected moderate myopes was recruited. Subjects completed the QIRC questionnaire for quality of life assessment. The functional and emotional QIRC scores were analysed separately. Visual disturbances were evaluated using the Halo and Glare Simulator, and contrast sensitivity was measured by the M&S Smart System II. All measurements were taken binocularly in 1 lux illumination. Spearman’s test was employed to evaluate the correlations. Results: The most common visual disturbance was diffuse glare. The functional QIRC score was significantly correlated with glare intensity (r = -0.54, P = 0.01). Whereas, the emotional QIRC score was significantly correlated with contrast sensitivity (r = 0.45, P = 0.04). Conclusion: The functional QIRC score is lower when the glare intensity is greater, and the emotional QIRC score is higher in person with greater contrast sensitivity. Hence, glare intensity and contrast sensitivity measurements are suggested to predetermine spectacle wearers’ functional vision and well-being, respectively
