Ages Eligible for Study:   40 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Subjects must have a clinically documented diagnosis of age-related bilateral cataracts that are considered amenable to treatment with standard phacoemulsification cataract extraction.
  • Subjects must require a spherical lens power from 10.00 D to 33.00 D
  • Subjects must have the potential for corrected distance visual acuity (CDVA) of 20/32 or better in both eyes, as documented by a Potential Acuity Meter

Exclusion Criteria:

  • Subjects with conditions with increased risk of zonular rupture, such as pseudoexfoliation syndrome. Zonular rupture during cataract surgery may affect postoperative centration, tilt, and stability of the lens.
  • Subjects who have any active inflammation or edema (swelling) of the cornea, including but not limited to the following: keratitis, keratoconjunctivitis, and keratouveitis.
  • Subjects with visually significant diabetic retinopathy (proliferative or non-proliferative) which reduces potential acuity to 20/32 or worse.
