In this randomized controlled trial, 96 eyes of females with dry eye will be recruited through random sampling. Dry eye assessments will be done including TBUT, Schirmer test 1, and OSDI questionnaire. 96 eyes will be divided into 3 groups (32 eyes each) and will be provided intervention which is Polyethylene Glycol 400 0.4%-Propylene Glycol 0.3%. , Dextran 0.1%Hypromellose 0.3%, and placebo(normal saline) through randomization by an unmasked investigator. Changes in central and peripheral corneal thickness will be evaluated by corneal topography. Patients will be evaluated at baseline, after 15 days, after 1 month, and re-evaluated after 1 month of cessation of treatment.
The purpose of this research is to the determine effect of dry eye and to compare the effect of artificial tears on central and peripheral corneal thickness.
