Abstract：Objective To investigate the value of maximum meridional incision combined with limbus relaxing incision(LRI)in cataract phacoemulsification surgery.Methods 100 cataract phacoemulsification patients who received treatment in the Ophthalmology Department of the Third People's Hospital of Nantong from January 2022 to December 2023 were selected and evenly divided into 2 groups with 50 cases each according to random number table method.The control group was treated with conventional corneal incision+astigmatism intraocular lens,and the observation group was treated with maximum meridian incision combined with LRI+aspherical intraocular lens.Naked eye visual acuity,best corrected visual acuity,residual corneal astigmatism,peripheral corneal thickness and complication rate were compared between the two groups before surgery,1 week,1 month and 6 months after surgery.Results 1 month after operation,the IOP and VAS scores of observation group were lower than the control group(P<0.05).The observation group had higher naked eye visual acuity and best corrected visual acuity at 1 week,1 month and 6 months after surgery than the control group(P<0.05).The residual astigmatism value and peripheral corneal thickness in the observation group were higher than the control group at 1 week,1 month,3 months and 6 months after surgery(P<0.05).The incidence of complications in the observation group was lower than the control group,the intergroup dif-ferences are statistically significant.(P<0.05).Conclusion The maximum meridian incision of the cornea combined with LRI has an obvious effect in cataract phacoemulsification surgery for patients with low-degree astigmatism.The naked eye vision and astigmatism of patients are significantly improved,and complications can be prevented,which can be referenced and promoted in clinical practice.
