简要总结
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.
详细描述
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 .

结局指标
主要结局
The position of IOL
时间窗: 6 months
Postoperatively, with the patient sitting upright,the position of IOL was assessed by slit lamp。Then ，We would calculate the rotation of IOL .
次要结局
- refraction astigmatism(6 months)
