Comparative Study Of Keratometer And Autorefractometer For Non-Invasive Tear Break-Up Time Measurement In Rural Settings

Tear break-up time (TBUT) is a crucial indicator of ocular surface health, often used in diagnosing dry eye syndrome. Traditional assessment methods may not be accessible in rural areas due to the high cost of advanced diagnostic machines. This study investigates the reliability and accuracy of keratometers and autorefractometers for measuring non-invasive TBUT in a cohort of 200 patients. Our findings indicate a strong correlation between TBUT values from these tools and the conventional invasive TBUT test, demonstrating their potential utility in resource-limited settings
