Abstract :
Aim: To compare incidence of dry eye between phacoemulsification and manual small incision cataract surgery.
Materials and Methods: This observational study included two groups. Group A consisted of 30 patients who had undergone manual small incision cataract surgery and Group B consisted of 30 patients who had undergone phacoemulsification. A detailed history was taken from all paricipants before they underwent a complete systemic and ocular examination which included best corrected visual acuity, slit lamp examination, intraocular pressure, and dilated fundus examination. Tests for dry eyes likes Schirmer’s test 1, tear film break up time (TBUT), tear meniscus height (TMH) was done postoperatively at 1 week, 3 weeks and 1 month postoperative. One test positive out of three was considered as a dry eye.
Results: The values of various tear film tests schirmer’s test, tear film break up time and tear meniscus height showed no significant difference between both groups (Chi square test P Value = 0.605,0.832, 1). There was no significant difference in incidence of dry eye in manual small incision cataract surgery and phacoemulsification (Chi square test p value = 0.317). On comparing the data with respect to age and sex, no significant difference in incidence of dry eye was seen between both groups or between male and female. There is high incidence of dry eye 33.33? seen in diabetic patients. (Chi square test P Value = 0.0371).
Conclusion: There is no significant difference in incidence of dry eye between manual small incision cataract surgery and phacoemulsification. We also found out high incidence of dry eye in diabetic patients.
