Abstract Details

Purpose:

To evaluate the results of high-cylinder toric intraocular lens (IOL) implantation in patients with cataract and high astigmatism.

Setting:

Department of ophthalmology, Eye and ENT hospital of Fudan University, Shanghai, China.

Methods:

72 eyes of 51 patients with cataract and more than 3.5 diopters (D) astigmatism were included in this retrospective study. All of the eyes underwent phacoemulsification and Acrysof toric IOL (SN6AT6, SN6AT7, SN6AT8, or SN6AT9) implantation and completed the follow up of at least one year. Uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), manifest, refractive and corneal cylinder (MC, RC, CC), surgically induced astigmatism (SIA), and complications were assessed. Rotation of the IOL and the grade of anterior capsular opacification (ACO) were evaluated after mydriasis.

Results:

19 patients were diagnosed as congenital cataract, and 34.59% had high myopia. Postoperatively, the mean UCVA was 0.65 �Â�± 0.21and the mean BCVA, 0.82 �Â�± 0.27. The mean preoperative corneal astigmatism and the average manifest refractive astigmatism at the last visit were 4.927D and 0.935D, respectively. The mean absolute rotation of the IOL was 7.21�Â�±4.29�Â�°. Toric IOL rotation was significantly and positively correlated with the degree of residual astigmatism in the T8 and T9 groups. Toric IOL rotation was positively correlated with axial length (AXL) and negatively correlated with ACO grade.

Conclusions:

Implantation of the high-cylinder toric IOL seems to be an effective, predictable, and safe procedure in patients with cataract and high astigmatism. Long AXL is a risk factor for toric IOL rotation, while higher ACO grade may improve the rotational stability of a toric IOL.
