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.
