Primary Outcome Measures:
  • Monocular Uncorrected Distance Decimal Visual Acuity [ Time Frame: Day 1-2, Day 7-14, Day 30-60, Day 120-180, Day 330-420 ]
    Visual acuity (VA) was tested monocularly (each eye separately) unaided at a distance of 5 meters (m) using a chart. VA was measured in decimal, with 1.0 decimal corresponding to 20/20 Snellen. A higher numeric value represents better visual acuity.

  • Monocular Uncorrected Near Decimal VA [ Time Frame: Day 30-60, Day 120-180, Day 330-420 ]
    VA was tested monocularly unaided at a distance of 40 centimeters (cm) using a chart. VA was measured in decimal, with 1.0 decimal corresponding to 20/20 Snellen. A higher numeric value represents better visual acuity.

Enrollment: 65
Study Start Date: May 2011
Study Completion Date: March 2013
Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: ReSTOR +3.0
AcrySof® IQ ReSTOR® +3.0 D Multifocal Toric IOL, model determined by preoperative keratometric astigmatism, bilateral implantation
Device: AcrySof® IQ ReSTOR® +3.0 D Multifocal Toric IOL
Multifocal IOL with extended secondary focal point and astigmatism correction implanted for long-term use over the lifetime of the cataract patient
Other Name: Models SND1T3, SND1T4, SND1T5, SND1T6

Detailed Description:
Eligible participants completed a preoperative examination of both eyes, implantation of the IOL at the operative visit for each eye, and up to 8 postoperative visits: Day 1-2, Day 7-14, and Day 30-60 after each implantation, and Day 120-180 and Day 330-420 after second eye implantation. The second implantation occurred within 30 days of the first.The primary eye was defined as the eye with higher astigmatism, with the other eye defined as the secondary eye. If both eyes had the same level of astigmatism, the first implanted eye was set as the primary eye.

Ages Eligible for Study:   20 Years and older   (Adult, Senior)
