Experimental: Crystalens AO
A silicone multi-piece accommodating intraocular lens
Device: Crystalens AO
Participants will undergo small incision cataract surgery (phacoemulsification). At the time of surgery, eligible participants will be implanted bilaterally with the Crystalens AO intraocular lens.
Active Comparator: SoftPort LI61AO
A silicone multi-piece foldable aspheric intraocular lens
Device: SoftPort LI61AO
Participants will undergo small incision cataract surgery (phacoemulsification). At the time of surgery, eligible participants will be implanted bilaterally with the SoftPort LI61AO intraocular lens.
- Amplitude of Accommodation [ Time Frame: Visit 4 (postoperative day 120-180) ]The measurement of optical change in the power of the eye when viewing from far to near. Accommodation decreases as age increases resulting in an inability to focus on near objects.
- Visual Acuity [ Time Frame: All visits through visit 4 (day 160-180) ]Number of correct letters on an early treatment diabetic retinopathy study (ETDRS) chart to measure distance visual acuity and the smallest readable print size on an Minnesota Low-Vision Reading (MNREAD) acuity chart for intermediate and near visual acuity (VA). Visual acuity measured in LogMAR.
