Clinical trial of sodium hyaluronate combined with recombinant human epidermal growth factor in the treatment of patients with dry eye after cataract operation
Objective To evaluate the effect of sodium hyaluronate combined with recombinant human epidermal growth factor(rhEGF)in the treatment of dry eye after cataract surgery.Methods Patients with dry eye after cataract surgery were divided into treatment group and control group.The control group was treated with sodium hyaluronate eye drops via dropping into the conjunctival sac,a drop per dose,tid,for 4 weeks.On this basis,the treatment group was treated with rhEGF eye drops via dropping into the conjunctival sac,1-2 drops per dose,tid,for 4 weeks.The two groups were compared on overall clinical efficacy,dry eye symptoms before treatment and after 4 weeks of treatment.Tear-film breakup time(BUT),basic tear secretion test(schirmer Ⅰ test,SⅠT),corneal fluorescein staining(CFS)score,meibomian gland yield secretion score(MGYSS),and the levels of tear inflammatory factors were compared between two groups before treatment and after 4 weeks of treatment.The safety was evaluated.Results Finally,41 cases and 39 cases were included in the treatment group and the control group,respectively.After treatment,the total effective rates in the treatment group and the control group were 95.12％and 79.49％,with statistically significant difference(P＜0.05).After 4 weeks of treatment,dry eye symptom scores of the treatment group and control group were 1.42±0.18 and 2.31±0.26;BUT were(11.89±1.26)and(10.46±1.27)s;SⅠT were(10.12±1.35)and(8.45±0.87)mm;CFS scores were 0.83±0.11 and 1.94±0.25;MGYSS scores were 10.85±1.17 and 12.43±1.56;interleukin-1β levels in tears were(35.26±3.53)and(74.12±7.55)ng·L-1;interleukin-6 levels were(8.35±0.86)and(12.41±12.56)pg·mL-1.Compared with the control group,the above indexes in the treatment group were statistically significant(all P＜0.05).The incidence rates of adverse drug reactions in the treatment group and the control group were 12.20％and 10.26％,without statistically significant difference between the groups(P＞0.05).Conclusion Sodium hyaluronate combined with rhEGF can significantly improve dry eye symptoms after cataract surgery,enhance the stability of tear film,reduce tear inflammatory factors,and protect the integrity of meibomian gland.
