  Purpose

The purpose of this study was to find out if in patients with non-exudative age-related macular degeneration (AMD), randomly assigned to cataract surgery, any AMD size progression or progression to exudative AMD could be detected 6 months after surgery.

Primary Outcome Measures:
  • AMD size (defined central region of interest) [ Time Frame: at enrollment, after 6 months ] [ Designated as safety issue: No ]
    To evaluate AMD size progression, absolute and relative differences in pixels of the ROI were cal-culated by equivalent tests.


Secondary Outcome Measures:
  • Functional ophthalmic assessments [ Time Frame: at enrollment, after 6 months ] [ Designated as safety issue: No ]
    Cataract grade (LOCS-III), Visual acuity (distance/near), contrast acuity tests, Visual Function Index (VF-14)


Enrollment: 54
Study Start Date: January 2002
Study Completion Date: July 2010
Primary Completion Date: September 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Control Group (CO)
Fifty-four patients with cataract and non-exudative age-related macular degeneration (AMD) were randomized into an early surgery group (ES=28) with immediate cataract surgery and a control group (CO=26) where surgery was performed after six months.
