Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Minimum 22 years of age
  • Bilateral cataracts
  • Preoperative keratometric cylinder in both eyes
  • Most appropriate toric IOL model choice (ZCT300 or ZCT400)
  • Predicted residual refractive cylinder, based on the AMO Toric IOL Calculator, must be:

  • Clear intraocular media other than cataract in each eye
  • Availability, willingness, ability and sufficient cognitive awareness to comply with examination procedures and study visits
  • Ability to understand, read and write English in order to consent to study participation and complete a study questionnaire
  • Signed informed consent and HIPAA authorization

Exclusion Criteria:

  • Irregular corneal astigmatism
  • Any corneal pathology/abnormality other than regular corneal astigmatism
  • Previous corneal surgery
  • Recent ocular trauma or intraocular surgery that is not resolved/stable or may affect visual outcomes
  • Any pupil abnormalities
  • Subjects with conditions associated with increased risk of zonular rupture, including capsular or zonular abnormalities that may lead to IOL decentration, including pseudoexfoliation, trauma, or posterior capsule defects
  • Known ocular disease or pathology that may affect visual acuity or that may require surgical intervention during the course of the study
  • Concurrent participation or participation during 30 days prior to preoperative visit in any other clinical study
  • Planned monovision correction
  • Patient is pregnant, plans to become pregnant, is lactating or has another condition associated with the fluctuation of hormones that could lead to refractive changes
