Efficacy comparison of two different surgery incisions on original corneal astigmatism in cataract surgery / 局解手术学杂志

ABSTRACT

Objective To compare the efficacy of two different surgery incisions on original corneal astigmatism in cataract surgery. Methods 300 patients (300 eyes) of cataract surgery from August 2012 to August 2013 in our hospital were included in the study,of which 150 patients in the observation group treated with transparent cornea incision in the steep axis of astigmatism,and the control group of 150 pa-tients received lateral ( right) or on the nose by the temporal side ( left) transparent cornea incision. Results In the third day,first month, third month,sixth month and 12th month after surgery,the average corneal astigmatism in the observation group was significantly lower than that before the surgery,which after a month the lowest ( +0. 79 ± 0. 92)D;average corneal astigmatism of patients in the control group were significantly higher than that before the surgery,corneal astigmatism after 3 days to reach the highest,( -5. 65 ± 0. 89)D,3 days after sur-gery,1 month, 3 months, 6 months and 12 months,patients in the observation group were significantly higher visual acuity patients,the differ-ence was statistically significant (P<0. 05). Conclusion Phacoemulsification clear corneal incision along the steep axis IOL implantation for cataract surgery can correct astigmatism original extent a certain extent,and to promote the recovery of visual acuity in patients with a grea-ter degree.
