Outcome Measures
Primary Outcomes (2)
Mean monocular best corrected distance visual acuity (BCDVA)
Retrospectively, the subject's medical records will be reviewed for assessments of BCDVA. Prospectively, visual acuity will be assessed for each eye individually with correction in place using letter charts placed at a distance of 6 meters (or 4 meters adjusted for infinity) from the subject. BCDVA will be reported in logarithm minimum angle of resolution (logMAR), where a logMAR value of 0 equates to 20/20 Snellen visual acuity (normal distance eyesight) and lower logMAR values indicate better visual acuity.
Up to 3 to 5 years post operative
Rate of protocol-specified ocular adverse events
The subject's medical records will be reviewed for medical conditions. Medical conditions that started after initial exposure to the study model IOLs will be captured as adverse events. The following adverse events are pre-specified for this outcome measure: * Cystoid macular edema (CME) * Hypopyon * Endophthalmitis * Lens dislocation * Pupillary block * Retinal detachment * Secondary surgical interventions
Up to 3 to 5 years post operative
Secondary Outcomes (8)
Mean manifest refraction - Sphere
Up to 3-5 years postoperative
Mean manifest refraction - Cylinder
Up to 3-5 years postoperative
Mean manifest refraction - Axis
Up to 3-5 years postoperative
Manifest refraction spherical equivalent (MRSE)
Up to 3-5 years postoperative
Mean monocular uncorrected distance visual acuity (UCDVA)
Up to 3-5 years postoperative
- +3 more secondary outcomes
Study Arms (2)
AcrySof single-piece IOL
Pseudophakic subjects previously implanted with an AcrySof single-piece IOL
AcrySof multi-piece IOL
Pseudophakic subjects previously implanted with an AcrySof multi-piece IOL
Interventions
Acrylic single-piece intraocular lens placed in the capsular bag in the posterior chamber of the eye during cataract surgery as a replacement for the natural crystalline lens.
Acrylic multi-piece intraocular lens placed in the capsular bag in the posterior chamber of the eye during cataract surgery as a replacement for the natural crystalline lens.
Eligibility Criteria
Subjects will be recruited from clinical sites in the United States and Canada.
You may qualify if:
- Subject is implanted with one of the study IOL models between 3 and 5 years previously.
- Subject follow-up is expected to be possible during the duration of the study.
- Subject or legally authorized representative must be able to understand and sign the IRB/EC approved Informed Consent form. Minor subjects will complete an Assent Form.
- Documented medical history and required pre-operative baseline information is available for retrospective data collection.
You may not qualify if:
- Subject is participating in a separate investigational drug or device study.
- Pregnancy at the time of enrollment.
