Comparison of the effect of small incision non-phacoemulsification and phacoemulsification surgery in the treatment of cataract

Abstract

Objective To compare the effect of small incision non-phacoemulsification and phacoemulsification 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-phacoemulsification 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.
