Abstract Aim of the work: The aim of this study is to evaluate changes in tear film function to detect dry eye disease (DED) in patients after uncomplicated phacoemulsification surgery for cataract removal. Patients and Methods: This is a retrospective clinical cohort study. The study included 30 eyes of 30 patients who underwent uncomplicated phacoemulsification surgery for cataract removal. Evaluation of lacrimal tear function was done using tear film break up time (TBUT), tear meniscus height (TMH) and Schirmer I test. All patients were followed up for one week, 1 & 3 months postoperatively with recording of the previously mentioned parameters. Results: The mean preoperative Schirmer I test, TBUT and TMH values were 12.36±3.1mm, 11.6±2.12 seconds, 336.2 ± 67.5μm, respectively decreased to 10.2±2.05 mm, 8.26±1.95 seconds, 321.8±60.9μm, respectively, at first postoperative week and to 8.61±1.72 mm, 8.49±2.14 seconds, 312.1±59.8μm, respectively, at the first month postoperatively. Then elevated after 3 months postoperatively to 11.1 ± 1.93 mm, 10.05 ± 1.98 seconds, 327.3 ± 63.5 μm, respectively. This decrease was statistically significant in all parameters except TMH. Conclusion: Dry eye disease is common after phacoemulsification surgery for cataract removal. The tear film changes are mostly temporary and became near to normal values approximately after 3 months.
