Abstract
PURPOSE: To determine the effects of topical diclofenac or betamethasone with concomitant application of topical rebamipide on the conjunctival goblet cell density in eyes after cataract surgery.
DESIGN: Randomized clinical trial.
PARTICIPANTS: Eighty patients who were scheduled for cataract surgery.
METHODS: Patients were randomized into 4 groups according to the postoperative topical drugs to be given; Group A, diclofenac alone; Group B, diclofenac and rebamipide; Group C, betamethasone alone; and Group D, betamethasone and rebamipide. Impression cytology was performed before and at 1 month after the surgery, and the mean density of goblet cells was determined.
RESULTS: The mean (± SD) density of goblet cells before the surgery in Group A was 257.0 ± 188.7 cells/mm(2), and it decreased significantly to 86.5 ± 76.7 cells/mm(2) at 1 month after the surgery (P = .002). In Group B, the goblet cell density was not statistically different between before (238.5 ± 116.6 cells/mm(2)) and at 1 month after the surgery (211.3 ± 184.4 cells/mm(2), P = .55). In Groups C and D, the mean density of goblet cells was decreased at 1 month after the surgery, but the decreases were not significant (P = .11 and P = .52, respectively).
CONCLUSION: After cataract surgery with postoperative topical diclofenac, the conjunctival goblet cell density was significantly reduced, and this reduction was blocked by the concomitant use of topical rebamipide. These results suggest that the concomitant use of topical rebamipide with nonsteroidal anti-inflammatory drugs is beneficial, especially in cases with postoperative dry eyes.
