Study Details

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.

Condition or Disease Intervention/Treatment Phase
  • Procedure: Cataract Surgery
N/A

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 .

Outcome Measures

Primary Outcome Measures

  1. The position of IOL [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 .

Secondary Outcome Measures

  1. refraction astigmatism [6 months]

    We would like to evaluate the improvement of refraction astigmatism after surgery.
