ABSTRACT

Objective To compare the effect of small incision non -phacoemulsification and phacoemulsifi-cation surgery in the treatment of cataract.Methods 90 patients with cataract were selected and randomly divided into ultrasound group and non -ultrasound group,45 cases in each group,who received small incision non -phac-oemulsification and cataract phacoemulsification surgery,respectively.The effect,dry eye symptom score,tear film breakup time and Schirmer test in the two groups were compared.Results The overall response rate in the ultrasound group (93.33%)was obviously higher than that in the non -ultrasound group(62.22%),the difference was statistically significant(χ2 =12.60,P <0.05).The dry eye symptom score[(3.34 ±0.31)points,(3.13 ±0.14)points]in the ultrasound group were significantly lower than those in the non -ultrasound group[(3.89 ±0.26)points,(3.46 ± 0.19)points]at postoperative 1 month and 3 months(t =9.12,9.38,all P <0.05).After the treatment,the tear film breakup time and Schirmer test [(7.34 ±0.45 )s,(5 .56 ±0.54)min]in the ultrasound group were significantly better than the non -ultrasound group[(5.55 ±0.42)s,(2.45 ±0.44)min](t =19.51,29.96,all P <0.05). Conclusion Phacoemulsification surgery exerts obvious effect in the treatment of cataract and induces non -obvious postoperative dry eye symptoms,it is significantly better than small incision non -phacoemulsification and has clinical significance.
