Outcome Measures

Primary Outcomes (1)

  • Rate of Severe Visual Distortions

    As assessed by a Patient Reported Outcomes (PRO) questionnaire. Subjects will be categorized as experiencing a severe visual distortion if they indicate "severe" as a response to any of the three visual distortion-related questions on the questionnaire.

    6 months

Study Arms (2)

Toric High Cylinder Power IOL

Toric high cylinder power intraocular lens implanted during cataract surgery in the first operative eye, with the second operative eye implanted within 30 days of the first implantation.

Device: SN6AT6 Intraocular LensDevice: SN6AT7 Intraocular LensDevice: SN6AT8 Intraocular LensDevice: SN6AT9 Intraocular Lens

Monofocal IOL

Monofocal intraocular lens implanted during cataract surgery in the first operative eye, with the second operative eye implanted within 30 days of the first implantation.

Device: SN60WF Intraocular Lens

Interventions

Acrylic intraocular lens with cylinder power at the IOL plane of 3.75 diopters. Intraocular lenses are implanted during cataract surgery as a replacement for the natural crystalline lens and are intended for long term use over the lifetime of the cataract subject.

Also known as: AcrySof® IQ Toric Model SN6AT6
Toric High Cylinder Power IOL

Acrylic intraocular lens with cylinder power at the IOL plane of 4.50 diopters. Intraocular lenses are implanted during cataract surgery as a replacement for the natural crystalline lens and are intended for long term use over the lifetime of the cataract subject.

Also known as: AcrySof® IQ Toric Model SN6AT7
Toric High Cylinder Power IOL

Acrylic intraocular lens with cylinder power at the IOL plane of 5.25 diopters. Intraocular lenses are implanted during cataract surgery as a replacement for the natural crystalline lens and are intended for long term use over the lifetime of the cataract subject.

Also known as: AcrySof® IQ Toric Model SN6AT8
Toric High Cylinder Power IOL

Acrylic intraocular lens with cylinder power at the IOL plane of 6.00 diopters. Intraocular lenses are implanted during cataract surgery as a replacement for the natural crystalline lens and are intended for long term use over the lifetime of the cataract subject.

Also known as: AcrySof® IQ Toric Model SN6AT9
Toric High Cylinder Power IOL

Acrylic aspheric monofocal intraocular lens. Intraocular lenses are implanted during cataract surgery as a replacement for the natural crystalline lens and are intended for long term use over the lifetime of the cataract subject.

Also known as: AcrySof® IQ Aspheric NATURAL Model SN60WF
Monofocal IOL

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Population will be selected from up to 80 clinical investigative sites.

You may qualify if:

  • Diagnosed with bilateral cataracts and in the targeted astigmatism range.
  • Planned cataract removal by phacoemulsification.
  • Pupil size greater than or equal to 6 mm after dilation.
  • Able to undergo second eye surgery within 30 days of first eye surgery.

You may not qualify if:

  • Irregular corneal astigmatism.
  • Any inflammation or swelling of the cornea.
  • Any corneal abnormality other than regular corneal astigmatism.
  • Previous corneal refractive surgery.
  • Amblyopia.
  • Diabetic retinopathy.
  • Uncontrolled glaucoma.
  • Currently participating in another investigational drug or device study that may confound the results of this investigation.
