Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Only adult subjects of either gender or any race in need of cataract extraction in both eyes were considered for enrollment. 280 subjects were implanted bilaterally with either the ACRYSOF® ReSTOR® Aspheric +3.0 D Add Power IOL Model SN6AD1 or the ACRYSOF® ReSTOR® Aspheric +4.0 D Add Power IOL Model SN6AD3 based upon a 1:1 randomization.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Subjects were examined to ensure inclusion/exclusion criteria. Only subjects who signed an informed consent and qualified to be in the study were enrolled. Subject numbers were assigned after obtaining consent meeting inclusion/exclusion criteria. Subjects were considered enrolled once implanted in the first operative eye.

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Data from one investigator, who implanted 20 subjects, were excluded from analysis due to non compliance with data collection and documentation. This resulted in 280 implanted subjects that were considered evaluable.
