Eligibility Criteria
Inclusion Criteria
- •Diagnosis of bilateral cataracts with planned clear cornea cataract removal;
- •Able to comprehend and willing to sign informed consent and complete all required postoperative follow-up procedures;
- •Calculated lens power between 13.0 and 30.0 Diopters (D);
- •Preoperative Best-corrected distance visual acuity (BCDVA) worse than 0.20 logMAR (ie, 0.22 logMAR or worse) in at least one eye;
- •Potential postoperative BCDVA of 0.20 logMAR or better in both eyes. Note: Subjects with any pathology that could reduce visual potential should not be enrolled in this trial;
- •Preoperative regular corneal astigmatism of \< 1.00 D, in both eyes;
- •Clear intraocular media other than cataract in both eyes;
- •Other protocol-specified inclusion criteria may apply.
Exclusion Criteria
- •Reasonably expected to require an ocular surgical treatment at any time during the study (other than YAG capsulotomy);
- •Previous refractive surgery or planned refractive surgery procedures throughout the entire duration of participation in the clinical study (including, but not limited to LASIK, astigmatic keratotomy and limbal relaxing incisions);
- •Clinically significant corneal abnormalities including corneal dystrophy, inflammation or edema;
- •Amblyopia;
- •Previous corneal transplant;
- •Any recurrent severe anterior or posterior segment inflammation of any etiology, and/or history of any disease producing an intraocular inflammatory reaction;
- •Rubella, congenital, traumatic, or complicated cataracts;
- •Glaucoma (uncontrolled or controlled with medication);
- •Degenerative eye disorders;
- •History of or current retinal conditions or predisposition to retinal conditions, previous history of, or a predisposition to, retinal detachment or presence of diabetic retinopathy;
Outcomes
Primary Outcomes
Least Squares Mean Binocular Uncorrected Intermediate Visual Acuity (UCIVA) (60cm) at Day 120-180
Time Frame: Day 120-180 from second eye implantation
VA was tested binocularly (both eyes together) with no refractive correction in place using an early treatment diabetic retinopathy study (ETDRS) chart set at 60 cm. VA was measured in "logarithm of the minimum angle of resolution" (logMAR), with 0.1 logMAR increment corresponding to 5 letters, or 1 line, on an ETDRS chart. A lower numeric value represents better visual acuity.
Secondary Outcomes
- Least Squares Mean Binocular Uncorrected Distance VA (4m) at Day 120-180(Day 120-180 from second eye implantation)
- Mean Photopic Binocular Defocus Curve at Day 120-180(Day 120-180 from second eye implantation)
- Mean Photopic Without Glare Binocular Distance Contrast Sensitivity at Day 120-180(Day 120-180 from second eye implantation)
- Least Squares Mean Binocular Uncorrected Near VA (40cm) at Day 120-180(Day 120-180 from second eye implantation)
- Mean Mesopic Without Glare Binocular Distance Contrast Sensitivity at Day 120-180(Day 120-180 from second eye implantation)
- Subject Satisfaction Recorded at Day 120-180(Day 120-180 from second eye implantation)
- Least Squares Mean Binocular UCIVA (60cm) at Day 120-180(Day 120-180 from second eye implantation)
- Mean Mesopic With Glare Binocular Distance Contrast Sensitivity at Day 120-180(Day 120-180 from second eye implantation)
- Mean Photopic With Glare Binocular Distance Contrast Sensitivity at Day 120-180(Day 120-180 from second eye implantation)
