  Purpose
This study will determine the ability of three different intraocular lenses to accommodate in patients who have previously undergone bilateral intraocular lens implantation.

Condition

Further study details as provided by Innovative Medical:

Primary Outcome Measures:
  • Amplitude of accommodation on COAS and how it correlates with: spherical aberration on the COAS, pupil size at near as measured with COAS, spherical aberration on the topography, patient reported nead for spectacles for reading [ Time Frame: one study visit ]

Secondary Outcome Measures:
  • Amplitude of accommodation on pushdown test - and how it compares to the COAS test results [ Time Frame: one study visit ]

Estimated Enrollment: 30
Study Start Date: October 2009
Study Completion Date: June 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Groups/Cohorts
Bilateral intraocular lens implantation.
