Comparison of the effect of phacoemulsification with corneal incision and marginal cornea incision in the treatment of senile cataract
Objective To compare the effect of phacoemulsification with corneal incision and corneal incision in the treatment of senile cataracts.Methods A total of 80 patients with senile cataracts were randomly divided into 2 groups.Both groups underwent phacoemulsification,the corneal incision was used in the control group,and the marginal corneoscleral incision was used in the observation group.Epithelial repair time,incision repair time,naked eye visual acuity,best corrected visual acuity(BCVA),corneal astigmatism,operative keratogenic astigmatism,break-up time(BUT),corneal fluorescein staining score(FLCs),Schirmer test(SIt)and postoperative complications rate were compared between the two groups.Results The time of epithelial repair and incision repair in the observation group was earlier than that in the control group(P＜0.05),while eye visual acuity,BCVA,BUT,Sit levels in the observation group were higher(P＜0.05).Corneal astigmatism,operative corneal astigmatism,and FLC levels in the observation group were lower than those in the control group at 1 week,2 weeks,and 4 weeks after surgery(P＜0.05).The incidence of postoperative complications in two groups(18％vs 12％)was no difference(P＞0.05).Conclusion The clinical effect of phacoemulsification with marginal corneoscleral incision in the treatment of senile cataracts is good,the postoperative corneal astigmatism of patients is lower,and the stability of visual acuity and tear film function is better.
