AIM:To conduct a comparative assessment of effects of AcrySof Toric intraocular lens(IOL) implantation and spherical IOL implantation combined with corneal limbus lysis in cataract surgery for the correction of corneal astigmatism.METHODS:A total of 53 patients(60 eyes)who underwent cataract surgery in cataract treatment center of our hospital from March 2008 to March 2009 were selected,all patients were complicated with regular corneal astigmatism,and their astigmatism was greater than 1D.According to the different surgical procedures,the subjects were divided into two groups.26 patients(30 eyes) were in simple phacoemulsification cataract extraction combined with AcrySof Toric IOL implantation group(including senile cataract of 24 patients(27 eyes),complicated cataract of 2 patients(3 eyes),while 27 patients(30 eyes) were in spherical IOL implantation combined with corneal lumbus lysis group(including senile cataract of 24 patients(27 eyes),complicated cataract of 3 patients(3 eyes).Before and 1st day,1st week and 3rd month after cataract surgery,two groups of subjects were measured uncorrected visual acuity,best corrected visual acuity(BCVA),computer optometry,and subjective refraction and recorded the spherical degree,cylinder degree and astigmatism axis and other data.And statistical analysis and observation of intracapsular stability of AcrySof Toric IOL were conducted.RESULTS:Followed-up for 6 months,AcrySof Toric group:uncorrected visual acuity more than 0.5 accounted for 93%,more than 0.8 accounted for 67%.Limbus lysis group:uncorrected visual acuity more than 0.5 accounted for 73%,more than 0.8 accounted for 50%.Optometry results before and 3 months after operation were compared and showed cylinder degree of small pupil optometry significantly reduced in both groups 3 months after operation,postoperative corneal astigmatism in AcrySof Toric group was lower than limbal lysis group,differences between the two groups was statistically significant(P<0.05),and stability of AcrySof Toric IOL implantation in the capsular bag was good,no more than 6 degrees of rotation was found during the follow-up of 3 months.CONCLUSION:AcrySof Toric IOL implantation can significantly improve uncorrected visual acuity and best corrected visual acuity in patients,at the same time can effectively reduce the postoperative astigmatism and improve visual quality.It has stable effect of surgery and is an effective way for treatment of cataract patients with astigmatism.
