Abstract:
Objective To observe the effect of limbal incision before and after phacoemulsification corneal astigmatism degree.Methods 46 patients with cataract (76 eyes) were randomly divided into two groups.23 cases (40 eyes) in group A received a temporal clear corneal incision phacoemulsification.23 cases (36 eyes) in group B received the upper clear corneal incision cataract ultrasound breast surgery.Results In group A,preoperative corrected visual acuity was (0.13 ±0.10)D,after 3 months of corrected visual acuity was (0.79 ± 0.13)D.In group B,preoperative corrected visual acuity was (0.14 ± 0.11)D,after 3 months of corrected visual acuity was (0.76 ± 0.15)D,the patients after 3 months corrected visual acuity was significantly improved than before treatment (t =4.127,P ＜0.01),the postoperative visual acuity was not statistically significant(t =0.605,P ＞ 0.05).Two groups postoperative corneal anterior surface,surface astigmatism values were gradually reduced,3 months after operation in group A after corneal anterior surface,surface astigmatism value were (0.45 ± 0.24) D,(0.09 ± 0.06) D ; those in B group were (0.52 ± 0.25) D,(0.09 ± 0.07) D,which were significantly lower than 1 week after operation and postoperation(t =2.232,2.128,all P ＜ 0.05).The remaining time two groups of corneal astigmatism value had no significant difference (P ＞ 0.05).Conclusion Temporal clear corneal incision phacoemulsification recovery of visual acuity is better,and less than the above changes of corneal astigmatism corneal incision operation.
