Description
Inclusion Criteria:
- Subjects must be 18 years of age or older on the date the Informed Consent Form (ICF) is signed.
- Subjects must have the capability to understand and provide written informed consent on the Institutional Review Board (IRB)/Independent Ethics Committee (IEC) approved Informed Consent Form (ICF) and authorization as appropriate for local privacy regulations.
- Subjects must have a Best-corrected Distance Visual Acuity (CDVA) equal to or worse than 20/40 in at least one eye, with or without a glare source, due to a clinically significant cataract (cortical, nuclear, subcapsular, or combination) that is considered amenable to treatment with standard phacoemulsification cataract extraction and capsular IOL implantation.
- Subjects must have a Best-corrected Distance Visual Acuity (CDVA) projected to be equal to or better than 20/32 after IOL implantation in each eye, as determined by the medical judgment of the Investigator or measured by potential acuity meter (PAM) testing, if necessary.
- Subjects must have clear intraocular media other than the cataract in both eyes.
- Subjects must have discontinued use of contact lenses for at least 2 weeks (for hard lenses) or 3 days (for soft lenses) prior to the pre-operative examination and must be willing to refrain from use of contact lenses throughout the clinical study.
- Contact lens wearers must demonstrate a stable refraction (within ±0.50 D for both sphere and cylinder) in both eyes, as determined by distance manifest refraction on two consecutive examination dates after discontinuation of contact lens wear.
- Subjects must require an IOL power from +16.0 diopter (D) to +27.0 D in both eyes.
- Subjects must be willing and able to comply with all treatment and follow-up study visits and procedures, and to undergo second eye surgery within 7-30 days of the first eye surgery.

- Subjects who have a history of chronic or recurrent inflammatory eye disease (e.g., iritis, scleritis, iridocyclitis, or rubeosis iridis) in either eye.
- Subjects who have a visual disorder, other than cataracts, that could potentially cause future acuity losses to a level of 20/ I 00 or worse in either eye.
- Subjects who have had previous intraocular or corneal surgery in either eye, with the exception of laser trabeculoplasty.
- Subjects with any preoperative infectious conjunctivitis, keratitis, or uveitis in either eye.
- Subjects who have a preoperative corneal astigmatism> 1.0 D in either eye as measured by corneal topography, irregular astigmatism, or skewed radial axis (note: corneal incisions intended specifically to reduce astigmatism are not allowed during the study).
- Subjects who cannot achieve a minimum pharmacologic pupil dilation of 5.0 mm in both eyes.
- Subjects who may be expected to require a combined or other secondary surgical procedure in either eye.
- Females of childbearing potential (those who are not surgically sterilized or at least 12 months postmenopausal) are excluded from enrollment in the study if they are nursing, lactating, currently pregnant or plan to become pregnant during the study. Females of childbearing potential must be willing to practice effective contraception for the duration of the study.
- Subjects with any other serious ocular pathology or underlying systemic medical condition (e.g., uncontrolled diabetes) or circumstance that, based on the Investigator's judgment, poses a concern for the subjects' safety or could confound the results of the study.
- Subjects with abnormal pupillary dilation dynamics (as determined by the medical judgment of the investigator) or eccentric or ectopic pupils in either eye.

|
Cumulative Rate of Secondary Surgical Interventions Due to the Optical Properties of the Lens
Time Frame: Day 120 to Day 180 after second eye IOL implantation
|
The cumulative rate of secondary surgical interventions (SSI) due to the optical properties of the lens, through Post-Operative Visit 4 (Day 120 to Day 180 after second eye IOL implantation).
The rate was determined as the number of eyes with an SSI related to the optical properties of the IOL divided by the total number of eyes.
