Abstract

Introduction: Postoperative dry eye and meibomian gland dysfunction (MGD) is common cause of
morbidity. Its cause is still elusive and probably multifactorial. Various studies in the past have thrown
some light on its mechanism but still we are not able to prevent its occurrence. Till date no study has
analyzed the role of topical steroid as one of the factors influencing postoperative MGD and dry eye.
Purpose: The aim of this study was to compare the symptoms and signs of MGD and dry eye in postcataract
surgery patients treated with topical dexamethasone-moxifloxacin versus topical prednisolonemoxifloxacin
combination eye drops.
Materials and Methods: Seventy eyes of seventy patients of senile cataract who had no dry eye
signs preoperatively, and had undergone uncomplicated phacoemulsification surgery were selected. The
patients were divided randomly into two study groups – Group 1 patients were started on dexamethasone
sodium phosphate -moxifloxacin hydrochloride and Group 2 patients were started on prednisolone acetate
– moxifloxacin hydrochloride combination eye drops postoperatively in a tapering dose for 6 weeks. The
data collected by scoring of clinical dry eye signs (corneal staining, TBUT, Schirmer test I and meibomian
gland dysfunction assessed by meibum expressibility and meibum quality score) and symptoms scoring by
SPEED II questionnaire. The study was done in both the groups preoperatively and at 1 week, 4 weeks
and 8 weeks postoperatively. Both the groups were compared using independent paired t- test and Mann –
Whitney test.
Results: The mean values of SPEED II, TBUT, corneal staining, meibomian gland expressibility, meibum
quality were statistically significantly higher in all followup visits (at 1week, 4 weeks, and 8 weeks) in
group 2 as compared to group 1.(p<.001).
Conclusion: Post cataract surgery patients treated with dexamethasone – moxifloxacin eye drops had
statistically significantly lesser symptoms and signs of dry eye and MGD as compared to patients treated
with prednisolone-moxifloxacin combination eye drops.
