Ophthalmol Update Jan ;16(4):823-5.
Background: Even after following successful cataract surgery and restoration of useful vision, the patient is not satisfied with the outcome. The main complain is burning , eye fatigue, foreign body sensation due to dry eye syndrome, which can adversely affect the quality of life. The symptoms of dry eye range from mild transient grittiness to persistent dryness, redness, itching, pain, burning sensation, ocular fatigue and visual disturbance. Aim: To evaluate the frequency of dry eyes after cataract surgery. Methodology: In our study we enrolled 200 patients from a private clinic in Hangu, District Kohat from October 2016 to September 2017. It was a conservative descriptive study. Out of them, 140 were male and 60 were female. Mostly they were in the age group of 61-70 years, Mean age was 60 +- 7 years. Result: TBUT was recorded for every patient at 1st, 2nd and 3rd week. Mean Tear Breakup Time (TBUT) was normal at 1st and 2nd week but got abnormal at 3rd week. It was probably normal first due to post-operative inflammation and glare. Difference between mean TBUT at 3rd visit was significant (P value = 0.0001). Conclusion; This study shows that TBUT one of the reliable test for dry eyes is normal immediately after surgery but gradually decreases. It may be due to prolonged use of steroids. Factors responsible for Dry Eye can be further investigated in order to eliminate them.
