Further study details as provided by Alcon Research:

Primary Outcome Measures:
  • Defocus Curve [ Time Frame: 3 months after surgery ]
    A defocus curve is created by multiple measurements of one's visual acuity at different spherical powers (recorded as Diopters (D)). Visual Acuity (VA) is measured in logMAR. LogMAR is the "logarithm of the minimum angle of resolution".

Enrollment: 65
Study Start Date: July 2010
Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: ReSTOR +3
Bilateral Implantation of ReSTOR +3 Intraocular lenses after cataract extraction
Device: ReSTOR +3
Bilateral implantation of ReSTOR +3 Intraocular Lenses (IOLs) after cataract extraction
Active Comparator: Tecnis MF
Bilateral Implantation of Tecnis Multifocal Intraocular lenses after cataract extraction
Device: Tecnis MF
Bilateral implantation of Tecnis Multifocal (MF) Intraocular Lenses (IOLs) after cataract extraction
