AIM: To investigate the effect of 1g/L diclofenac sodium eye drops after corneal stem cell transplantation in the treatment of pterygium.

METHODS: From January 2009 toApril 2012, 76 cases 104 eyes which underwent corneal stem cell transplantation in the treatment of pterygium in our hospital were randomly divided into diclofenac sodium eye drops group(trial group)and control group. The corneal irritation, healing of epithelium, corneal scar, conjunctival wound healing time and recurrence were observed and compared between the two groups.

RESULTS: There was much lighter symptom of corneal irritation in the trial group than in the control group on 1^st, 3^rd and 5^th day after operation(P<0. 05), but the others have no significant difference(P>0. 05).

CONCLUSION:1g/L diclofenac sodium eye drops is effective and safe in reducing corneal irritation after cornealstem cell transplantation in the treatment of pterygium.
