Eligibility Criteria
Inclusion Criteria:
- Sphere more than -6.0D;
- Cornea astigmatism from -1.0 D to -4.0D;
- Clinical diagnosis of complicated cataract;
- Ask for and accept refractive lens exchange surgery;
- Accept AcrySof Toric intraocular lens .
Exclusion Criteria:
- Other eye diseases induces impaired vision ,such as retinal detachment,keratoconus,pterygium,glaucoma,choroidal detachment,vitreous hemorrhage,congenital cataract,lens dislocation,anterior uveitis ,pupil deformation and so on;
- Previous corneal or intraocular surgery;
- Refuse surgery;
- Refuse to use AcrySof Toric intraocular lens .

Outcomes
Primary Outcome Measures
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 .
Secondary Outcome Measures
refraction astigmatism
We would like to evaluate the improvement of refraction astigmatism after surgery.

5. Study Description
Brief Summary
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.
Detailed Description
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 .
