Application of Strong Axis Corneal Incision in Phacoemulsification in Cataract Patients
Objective:To investigate the effect of phacoemulsification with strong axis corneal incision in cataract patients.Methods:260 cataract patients who were treated in the hospital from October 2021 to October 2022 were selected as the research objects.All patients were treated with phacoemulsification.According to different surgical incisions,they were divided into observation group(n=146,strong axis corneal incision)and control group(n=114,right superior or temporal clear corneal incision).The surgical incision was 3 mm.The best corrected visual acuity(BCVA)and corneal astigmatism were compared between the two groups before surgery,1 month and 3 months after surgery.Results:BCVA was higher and corneal astigmatism was lower in the observation group than that in the control group at 1 month and 3 months after operation(t=2.975,2.055;t=7.019,9.427;P＜0.05).Compared with the control group,the total incidence of complications such as hyphema,corneal incision burn,posterior capsule rupture and posterior corneal edema was lower in the observation group(χ2=4.572,P＜0.05).Conclusion:The strong axis corneal incision is a good incision for phacoemulsification,which is helpful to the recovery of visual acuity.It has little effect on corneal astigmatism and can reduce the incidence of postoperative complications.
