Methods: In this observational study, 503 patients were screened for dry eye on the basis of questionnaire adopted from Dry Eye Workshop questionnaire which included five symptoms. On the basis of two or more than two symptoms, patients were divided into two groups Group I and Group II respectively. All patients underwent routine ophthalmological examination along with evaluation of tear parameters like Schirmer's test I, tear film break-up time, slit lamp assisted tear meniscus height measurement, Rose Bengal staining and tear film thinning time. On the basis of questionnaire and tear parameters, 235 patients were found eligible for the study. Final grading of dry eye into four grades was done according to Dry Eye Workshop. Severity of dry eye was divided into three grades as mild, moderate and severe with total score of 4 respectively. The data was analysed by using Pearsonís correlation of coefficient and multiple comparison tests with SPSS 22 version. P value
