Brief Summary:
The purpose of this study is to determine the safety and effectiveness of the IC-8 IOL implanted in one eye and a monofocal or monofocal toric IOL implanted in the fellow eye in accordance with the indication.

Condition or disease Intervention/treatment Phase
Cataract Presbyopia Device: IC-8 IOL Group Device: Control Group Not Applicable

Detailed Description:
Eligible patients will complete up to 12 study visits over a 12-month period. All subjects will complete a preoperative examination of both eyes to assess study eligibility: operative visit (each eye) and up to 9 postoperative visits (Day 1 - each eye, Week 1 - each eye, Month 1 - each eye or combined, Month 3 - both eyes, Month 6 - both eyes, and Month 12 - both eyes). The first eye must meet specific qualification criteria in order to proceed with IOL implantation in the second eye. The second eye should be implanted within 45 days of the first eye.

Primary Outcome Measures :
  1. Mean Binocular Photopic Uncorrected Intermediate (66 cm) Visual Acuity (UCIVA) [ Time Frame: 6 Months (160-210 days post second eye operative visit) ]
    Visual acuity (VA) was tested binocularly (both eyes) at a distance of 66 cm, without manifest refraction, using an Early Treatment Diabetic Retinopathy Study (ETDRS) chart presenting on a self-calibrating monitor in a computerized testing system. Visual acuity was measured in logarithm of the minimum angle of resolution (logMAR), with a 0.02 logMAR increment corresponding to a single letter on the ETDRS chart.

  2. Mean Binocular Photopic Uncorrected Near (40 cm) Visual Acuity (UCNVA) [ Time Frame: 6 Months (160-210 days post second eye operative visit) ]
    Visual acuity (VA) was tested binocularly (both eyes) at a distance of 40 cm, without manifest refraction, using an Early Treatment Diabetic Retinopathy Study (ETDRS) chart presenting on a self-calibrating monitor in a computerized testing system. Visual acuity was measured in logarithm of the minimum angle of resolution (logMAR), with a 0.02 logMAR increment corresponding to a single letter on the ETDRS chart.

  3. Mean Binocular Photopic Uncorrected Distance (4 m) Visual Acuity (UCDVA) [ Time Frame: 6 Months (160-210 days post second eye operative visit) ]
    Visual acuity (VA) was tested binocularly (both eyes) at a distance of 4 m, with +0.25 D infinity adjustment lens in front of the eyes, using an Early Treatment Diabetic Retinopathy Study (ETDRS) chart presenting on a self-calibrating monitor in a computerized testing system. Visual acuity was measured in logarithm of the minimum angle of resolution (logMAR), with a 0.02 logMAR increment corresponding to a single letter on the ETDRS chart.

  4. Mean Monocular Photopic Distance-Corrected Intermediate (66 cm) Visual Acuity (DCIVA) in IC-8™ IOL Eyes [ Time Frame: 6 Months (160-210 days post second eye operative visit) ]
    Visual acuity (VA) was tested monocularly (each eye) at a distance of 66 cm, with the distance manifest refraction (with infinity adjustment) in place for that eye, using an Early Treatment Diabetic Retinopathy Study (ETDRS) chart presenting on a self-calibrating monitor in a computerized testing system. Visual acuity was measured in logarithm of the minimum angle of resolution (logMAR), with a 0.02 logMAR increment corresponding to a single letter on the ETDRS chart.

  5. Mean Monocular Photopic Depth of Focus (DOF) in IC-8™ IOL Eyes [ Time Frame: 3 Months (60-110 days post second eye operative visit) ]
    Depth of focus was performed monocularly in the IC-8™ IOL Group at the far to near range of vision (+2.00 to -5.00 D), using 100% contrast ETDRS charts in a computerized testing system calibrated for a 4 m test distance, with manifest refraction (no infinity adjustment) in place for the eye(s) being tested. The defocus power was progressively introduced in 0.50 D increments from +2.00 D to +0.50 D and from -0.50 D to -5.00 D, then in 0.25 D increments from +0.50 D to -0.50 D, while visual acuity was measured at each successive defocus step. The depth of focus was estimated as the defocus range between zero defocus and the first point on the negative lens induced mean defocus curve that crosses the 0.2 logMAR using a linear interpolation.

  6. Mean Monocular Best-corrected Distance (4 m) Visual Acuity (BCDVA) [ Time Frame: 12 Months (300-420 days post second eye operative visit) ]
    Visual acuity (VA) was tested monocularly (each eye) at a distance of 4 m, in photopic conditions, with manifest refraction in place (no infinity adjustment) using an Early Treatment Diabetic Retinopathy Study (ETDRS) chart presenting on a self-calibrating monitor in a computerized testing system. Visual acuity was measured in logarithm of the minimum angle of resolution (logMAR), with a 0.02 logMAR increment corresponding to a single letter on the ETDRS chart.

  7. Proportion of IC-8™ IOL Eyes Achieving Best-corrected Distance Visual Acuity (BCDVA) 0.3 logMAR or Better Compared to the Safety and Performance Endpoints (SPE) Rates [ Time Frame: 12 Months (300-420 days post second eye operative visit) ]

Visual acuity was measured in logarithm of the minimum angle of resolution (logMAR), with a 0.02 logMAR increment corresponding to a single letter on the ETDRS chart.

  8. Proportion of Best-Case IC-8™ IOL Eyes Achieving Best-corrected Distance Visual Acuity (BCDVA) 0.3 logMAR or Better Compared to the Safety and Performance Endpoints (SPE) Rates [ Time Frame: 12 Months (300-420 days post second eye operative visit) ]

Visual acuity was measured in logarithm of the minimum angle of resolution (logMAR), with a 0.02 logMAR increment corresponding to a single letter on the ETDRS chart. Monocular BCDVA for the IC-8™ IOL eyes of subjects in the Best-Case population was compared to the safety and performance endpoints (SPE) rate for posterior chamber IOLs.

  9. Rates of IC-8™ IOL Eyes With Cumulative Ocular Serious Adverse Events [ Time Frame: Through 12 Months (300-420 days post second eye operative visit) ]

Secondary Outcome Measures :
  1. Tolerance to Preoperative Corneal Astigmatism in IC-8™ IOL Eyes With BCDVA 20/25 at 3 Months [ Time Frame: 3 Months (60-110 days post second eye operative visit) ]
    Uncorrected-distance visual acuity (UCDVA) in IC-8™ IOL eyes achieving best-corrected distance visual acuity (BCDVA) of 20/25 or better was compared between eyes with preoperative corneal astigmatism < 1.0 D to eyes with 1.0 D to 1.5 D of preoperative corneal astigmatism.

  2. Mean Monocular Photopic Contrast Sensitivity Without Glare [ Time Frame: 6 Months (160-210 days post second eye operative visit) ]
    Contrast sensitivity (the ability to distinguish between an object and it's background) was evaluated in a subgroup of subjects and was tested monocularly (each eye) in photopic (well-lit) conditions, without a glare source, using sine waving gratings in a computerized testing system. The photopic spatial frequencies tested were 3, 6, 12, 18 cycles per degree (cpd). When a subject was unable to see the highest contrast grating, the highest contrast score was assigned. Raw scores (0 to 9) from contrast sensitivity testing were transformed to log units. Better contrast sensitivity results are reflected by a higher numeric value.

The photopic spatial frequencies tested were 3, 6, 12, 18 cycles per degree (cpd). When a subject was unable to see the highest contrast grating, the highest contrast score was assigned.
