Investigation of the Safety and Effectiveness of a Trifocal IOL

This study is a prospective, multicenter, randomized, double masked confirmatory trial comparing an investigational trifocal intraocular lens (IOL) and a commercially available monofocal IOL.

The study will include adult subjects with operable cataracts in both eyes who are eligible for phacoemulsification cataract surgery followed by IOL implantation.

Eligibility Criteria:
Inclusion Criteria:

1. Male or female adults, age 22 years or older at the Preoperative Visit.
2. Visually significant cataracts in both eyes that are eligible for phacoemulsification cataract surgery.
3. Willing to undergo cataract surgery in the second operative eye within 7 - 30 days after surgery in the first eye.
4. Projected Best Corrected Distance Visual Acuity (BCDVA) of 0.2 logMAR (20/32 Snellen) or better in each eye after cataract surgery/IOL implantation, as determined by the medical judgement of the Investigator
5. Eligible for receipt of an IOL power within the range of the investigational IOL (+10.0 D to +30.0 D, in 0.50 D increments) in each eye
6. Contact lens users must be willing to discontinue wear of their lenses in accordance with the following requirements:

   * Rigid gas permeable lenses for ≥ 7 days prior to the Preoperative Visit
   * Soft contact lenses for ≥ 3 days prior to the Preoperative Visit Contact lens wearers must demonstrate a stable refraction (within ±0.50 D for both sphere and cylinder) in each eye, as determined by manifest refraction on two consecutive examination dates at least one week apart after discontinuation of contact lens wear.
7. Provide signed written consent prior to participation in any study-related procedures.
8. Ability, comprehension, and willingness to follow study instructions, and likely to complete all study visits.
9. Female subjects must be 1-year postmenopausal, surgically sterilized, or, if of childbearing potential, have a negative urine pregnancy test at the Preoperative Visit. Women of childbearing potential must use an acceptable form of contraception throughout the study. Acceptable methods include at least one of the following: intrauterine (intrauterine device), hormonal (oral, injection, patch, implant, ring), barrier with spermicide (condom, diaphragm), or abstinence.

Exclusion Criteria:

1. History or presence of, or predisposition to, degenerative visual disorders (e.g., macular degeneration, retinal detachment, proliferative diabetic retinopathy, or other retinal disorders) predicted to result in BCDVA worse than 0.2 LogMAR (20/32 Snellen) in either eye during the study participation period.
2. Significant anterior segment pathology in either eye that might increase intraoperative risk or compromise IOL stability (e.g., pseudoexfoliation syndrome)
3. Reasonably expected to require secondary ocular surgical intervention or laser treatment other than YAG capsulotomy in either eye during the study participation period.
4. Presence of one or more clinically significant corneal abnormalities in either eye, including corneal dystrophy, irregularity, or edema per the Investigator's medical opinion.
5. Previous intraocular, corneal, or retinal detachment surgery, including corneal transplant, LASIK, astigmatic keratotomy and limbal relaxing incisions in either eye
6. Rubella, congenital, traumatic or complicated cataract in either eye
7. Preoperative keratometric astigmatism \> 1.0 D or irregular corneal astigmatism in either eye (Note: corneal incisions intended to reduce astigmatism are not permitted)
8. Clinically significant ocular inflammation or infection present ≤ 30 days in either eye prior to the Preoperative Visit.
9. Presence or history of one or more severe/serious ocular conditions (e.g., glaucoma, uveitis, ocular infection, severe dry eye) in either eye, or any other unstable medical condition (e.g., uncontrolled diabetes) that in the opinion of the Investigator would put the subject's health at risk, confound the results of the study and/or prevent the subject from completing all study visits.
10. Use of medications known to interfere with visual performance, pupil dilation, or iris structure ≤ 30 days prior to the Preoperative Visit.
11. Participation in any study of an investigational, interventional product within 30 days prior to the Preoperative Visit or at any time during the study period.
12. Pregnant or nursing females.
