An interventional study of Cataract Surgery in Cataract, sponsored by Wenzhou Medical University. Completed at 1 site in China. Open to participants aged 30 Years to 80 Years. Per ClinicalTrials.gov, last updated 2012-07-06.

The purpose of this study is to evaluate the stability and efficacy of The AcrySof Toric intraocular lens in the bag in high myopic subjects.
According to numerous estimations, 15% to 29% of patients with cataract have≥1.5 diopters (D) of refractive astigmatism. New toric IOL designs (Acrysof © toric IOL; Alcon), approved by the US Food and Drug Administration (FDA) at the end of 2005, have been found to be more stable and safety in the capsular bag in subjects with normal axis length of eye. Then,this study aims at the confirmation of the stability of The AcrySof Toric intraocular lens in the bag in high myopic subjects.Then we may find a more effective treatment for the high myopic patients with complicated cataract and sever cornea astigmatism .
1,726 studies on the registry are indexed under Cataract; 230 are open to participants now.
This study's enrollment of 30 is below the median of 80 across 1,171 interventional studies indexed under Cataract.

Exclusion Criteria:
Take the operation of phacoemulsification and implant the AcrySof Toric intraocular lens into the capsular bag in high myopic subjects.
Also known as: refractive lens exchange surgery
The position of IOL
Postoperatively, with the patient sitting upright,the position of IOL was assessed by slit lamp。Then ，We would calculate the rotation of IOL .
Time frame: 6 months
refraction astigmatism
We would like to evaluate the improvement of refraction astigmatism after surgery.
Time frame: 6 months
