AIM: To evaluate the effects of hyaluronic acid sodium eye drops on tear film after pterygium transposition

METHODS: All 68 cases(76 eyes)after pterygium transposition were chosen and randomly divided into two groups: the hyaluronic acid sodium group and control group. In the hyaluronic acid sodium group, the patients were treated by hyaluronic acid sodium eye drops after pterygium transposition. In the control group, the patients were not treated by hyaluronic acid sodium eye drops. The tear film break-up time(BUT), the time of tear secretion( Schirmer Ⅰ test, SⅠt)and corneal fluorescein staining(CFS)were observed by the slit-lamp before operation, 1 day, 7, 14, 30 days after operation.

RESULTS: There was no statistical difference between groups before operation and 1 day after operation(P>0.05). After treatment, the BUT, SⅠt and CFS were significantly different(P<0.05).

CONCLUSION:Hyaluronic acid sodium eye drops can be effective on functional restoration of tear film after pterygium transposition.
