Dry eye is a significant concern following cataract surgery, impacting patients’ ocular comfort and daily activities. This prospective study, conducted over a year( from 01/01/2023 to 31/12/23 ), focused on presenile patients (30-50 years) undergoing elective cataract surgeries. The aims were to identify factors contributing to postoperative dry eye and determine its incidence. Various parameters, including incision size, topical eye drops, microscopic light exposure, and intraocular irrigation, were assessed. Results revealed a 60% incidence of dry eye after surgery. Larger incisions (7mm) and the use of preservative-containing eye drops correlated with higher dry eye percentages (40% and 80%, respectively). Prolonged microscopic light exposure (26-30 minutes) and vigorous intraocular irrigation (15 minutes) also contributed to increased dry eye cases (70% and 80%, respectively). The study highlights the importance of minimizing surgical impact on the ocular surface. Counselling patients about potential postoperative dry eye symptoms and adopting strategies such as smaller incisions, preservative-free drops, and careful irrigation may enhance overall patient satisfaction and outcomes
