The purpose of this study is to look at how well you see the Nanoflex Intraocular lens placed in your eye.

Inclusion Criteria:

• Male or female patients at least 18 years of age.
• Patients who have bilateral NanoFlex implantation at least 3 months previously.
• No significant ocular pathology causing DCVA to be less than 20/25 or causing significant visual loss.
• DCVA of 20/25 or better in both eyes.
• Spherical equivalent in the dominant eye to be +/-.50 or less and in the non-dominant eye to be between-1.00 and -1.87.
• Uncorrected VA in dominant eye 20/25 or better.

Exclusion Criteria:

• History of ocular trauma or prior ocular surgery (minor ocular trauma is allowed such as small superficial corneal scar not effecting vision; some prior ocular surgery is allowable so long as it has not impacted visual acuity.
• Amblyopia or strabismus, significant visual field loss, or posterior capsular opacifcation.
• Known pathology that may affect visual acuity; particularly retinal changes that affect vision (macular degeneration, cystoid macular edema, proliferative diabetic retinopathy, etc.).
