AIM:To evaluate the effect of Yangxue Runmu formula combined with sodium hyaluronate on dry eye after cataract surgery by ocular surface analyzer.

METHODS: Totally 80 patients with dry eye after cataract surgery in our hospital from June 2019 to December 2020 were selected and divided into control group and observation group by random number table method, 40 cases in each group. The control group was treated with sodium hyaluronate eye drops, and the observation group was treated with Yangxue Runmu formula combined with sodium hyaluronate eye drops. The index levels of ocular surface analyzer and fluorescein staining(FL)score were compared between the two groups.

RESULTS: After treatment, the wet length of tear film, first non-invasive tear break-up time(NIBUTf), average non-invasive tear break-up time(NIBUTav)and tear meniscus height(LTMH)in the two groups were markedly higher than those before treatment(all P<0.01), and the observation group were markedly higher than those in the control group(P<0.05); after treatment, the conjunctival hyperemia score, meibomian gland loss score, FL score in the two groups were markedly lower than those before treatment(all P<0.01), and the observation group were markedly lower than those in the control group(all P<0.01); there were no obvious adverse reactions in the two groups.

CONCLUSION: Through the evaluation and analysis of ocular surface analyzer, Yangxue Runmu formula combined with sodium hyaluronate can effectively improve the ocular surface function of patients after cataract surgery, and has good safety.
