Objective: The purpose of our research is to determine the prevalence and determinants of dry eyes in participants who undergo cataract surgery.

Methods: Liaquat University of Medical & Health Sciences Jamshoro conducted the study for six months. The study involved 150 subjects with senile cataracts and preexisting dry eye syndrome. The medical histories and ocular conditions of the subjects were evaluated in order to determine if they contributed to dry eye.

Results: Participants' mean age was 60.36±9.88 years and most (91, 60%) were male. During the first week after surgery, as a result of Schirmer's tests, the values ranged from 11 to 36 mm, and after a month, the values ranged from 7 to 25 mm. Schirmer’s test was used in preoperative clinical evaluation to assess dry eye. According to the TBUT data, the mean was 14.52±1.92 (range 11-19 s). A significant increase in dry eye risk at 1 week was seen in the phacoemulsification group with exposure times >15 minutes (p=0.007).

Conclusion: A high number of patients develop dry eye after cataract surgery, regardless of demographics and anthropometric, surgical type, microscope exposure time, and energy input. As a transient condition, this dryness subsided in one month, eventually returning to normal.
