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.

Mean Monocular Photopic Depth of Focus (DOF) in IC-8™ IOL Eyes
Time Frame: 3 Months (60-110 days post second eye operative visit)

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.
