Title: Clinical studies on AcrySof Toric intraocular lens
Abstract: ObJective To evaluate the efficacy and rotational stability of AcrySof Toric intraocular lens implantation to correct Uygur preexisting comeal astigmatism in cataract surgery.Methods Thirty-eight cataract patients (49 eyes) from Shihezi People's Hospital with corneal astigmatism greater than 1.0D were involved in this study and randomized into two groups.Group A (Experimental group) with 15 patients (19 eyes) and group B (Control group) with 23 patients (30 eyes) both received AcrySof Toric IOL implantation.Uncorrected distant visual acuity (UCDVA),best corrected visual acuity (BCDVA),residual astigmatism,rotational stability of intraocular lens and spectacles independence were observed.Results Patients with UCDVA 0.8 or better accounted for 73.7%(14/19),84.2%(16/19),89.5%(17/19) and 76.7%(23/30),86.7%(26/30),93.3%(28/30),in group B,respectively.There were significant differences between two groups 1 week,1 month and 3 months after operation (P >0.05).There was no statistically significant differences in BCDVA between the two groups (P >0.05).There were no significant differences in preoperative comeal astigmatism and corneal astigmatism 3 months after operation in the two groups respectively (P >0.05).There were significant differences in the mean residual astigmatisms between the two groups 1 week,1 month and 3 months postoperatively (P >0.05).The mean Toric IOL axis rotation was less than 5 degrees 3 months postoperatively.Spectacles were not necessary in 89.5%(17/19) and 93.3%(28/30),cases in group A and B,respectively.No eye had intraoperative or postoperative complications.Conclusions AcrySof Toric IOL is effective in astigmatism correction which shows good rotational stability.And it is also effective option to correct preexisting corneal astigmatism in cataract surgery,No obvious racial difference.
