ABSTRACT
·AIM: To evaluate meibomian gland dysfunction (MGD) after phacoemulsification surgery,and to discuss the potential impact of ocular surface. ·METHODS: A perspective, self-controlled clinical trial was conducted. Fifty-six eyes of 56 patients with MGD underwent phacoemulsification and were evaluated the ocular surface disease index (OSDI), meibography score,lid margin abnormalities, Schirmer test, tear film break - up time ( BUT ) at preoperatively and postoperatively 2wk,1 and 3mo. ·RESULTS: Schirmer test did not change significantly postoperatively ( P > 0. 05 ). The OSDI scores, meibography score, lid margin abnormalities increased at 2wk, 1 and 3mo postoperatively compared to before operation (all P<0.05);BUT decreased (P<0.05). · CONCLUSION: Meibomian gland function may be aggravated after phacoemulsification surgery.
