Evaluation of Visual Outcomes of Monovision Patients Bilaterally Implanted With Nanoflex Intraocular Lenses

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.).
