Abstract:
Objective To compare the changes of corneal endothelial cells in early recovery period after 1.8 mm small incision phacoemulsification nucleus chopping and conventional incision phacoemulsification for cataract.Methods Fifty-three patients with cataract were divided into the observation group and control group according to different operation methods.The observation group was treated with 1.8 mm small incision phacoemuisification nucleus chopping while the control group was treated with routine incision phacoemuisification.The visual acuity,degree of astigmatism,corneal endothelial cell indexes and complications were observed.Results The effective ultrasound time and average ultrasonic energy of the observation group were significantly less than those of the control group (all P ＜ 0.05).Compared with 1 day before operation,the visual acuity,degree of astigmatism,corneal endothelial cell area (ECA) and coefficient of variation (CV) were significantly increased at 1 week and 4 weeks after operation,and corneal endothelial cell density (ECD) was significantly decreased (all P ＜ 0.05).The visual acuity and ECD levels of the observation group at 1 day,1 week and 4 weeks after operation were significantly higher than those of the control group,while the degree of astigmatism,ECA and CV were significantly lower than those of the control group (all P ＜ 0.05).Conclusion Compared with the traditional incision phacoemulsification,the damage of 1.8 mm small incision phacoemulsification nucleus chopping to corneal endothelial cells is significantly milder,can reduce the effective ultrasound time and average ultrasonic energy,decrease the degree of astigmatism,improve the visual acuity and decrease the corneal edema.
