Primary Outcome Measures:
  • Best-corrected visual acuity (BCVA) [ Time Frame: Six months ]
    The best-corrected visual acuity is assessed with glasses after cataract operation

Secondary Outcome Measures:
  • Posterior capsule opacification [ Time Frame: Six months ]
    The posterior capsule opacification is assessed by slit lamp examination and subjective grading

Enrollment: 9
Study Start Date: May 2008
Study Completion Date: August 2009
Primary Completion Date: August 2009 (Final data collection date for primary outcome measure)

Detailed Description:
In this prospective case series the Corneal Quatrix Evolutive IOL was implanted in 14 eyes of nine patients with senile cortico-nuclear cataract. A standardized surgical technique and post-operative regimen were applied. Six months postoperatively best corrected visual acuity (BCVA), refraction and complications (especially) posterior capsule opacification (PCO) were analysed.
