Brief summary

The objective is to evaluate refractive stability (spherical equivalent change ≤ 0.50D from 1-month to 3-months).

Detailed description

This study is a single-arm, evaluator masked clinical evaluation study of refractive stability, after successful bilateral cataract surgery. Subjects will be assessed pre-operatively, operatively and at 1 month and 3 months post-operatively. Clinical evaluations will include measurement of bilateral visual acuity, manifest refraction, and defocus curve.

Inclusion criteria

Subjects are eligible for the study if they meet the following criteria: Note: Ocular criteria must be met in both eyes. * Presenting for uncomplicated bilateral cataract surgery and have an interest in an IOL option * Gender: Males and Females. * Age: 50 or older * Willing and able to provide written informed consent for participation in the study * Willing and able to comply with scheduled visits and other study procedures. * Have good ocular health, with no pathology that compromises visual acuity (outside of residual refractive error and cataract) * Potential postoperative visual acuity of (20/25 Snellen) or better in both eyes
