A Planned Study at Multiple Sites is Being Done to Compare the Results of Two Types of Trifocal Toric Intraocular Lenses Used in Cataract Surgery

Trifocal lenses are part of the premium range of refractive-diffractive trifocal IOLs with advanced aspheric optics for excellent visual outcomes. They are single piece, posterior chamber foldable intraocular lenses. The optic is refractive-diffractive trifocal with the anterior surface being aspheric and the posterior surface with a square edge design. The lens is designed to provide all near, distance and intermediate vision and thereby reduce spectacle dependency. Toric version of trifocal intraocular lens is intended to correct astigmatism.

Inclusion criteria

• Patient willing to sign inform consent form.
• Clear intraocular media other than cataract.
• Female participants of childbearing potential must be willing to ensure that they use effective contraception during the study.

Exclusion criteria

• Previous intraocular or corneal surgery.
• Traumatic cataract
• Pregnancy (as stated by patient) or lactation.
• Concurrent participation in another drug or device investigation.
• Irregular astigmatism.
• Patient receiving chlorquine treatment.
• Subjects with any systemic disease that could increase operative risk or confound the outcome.
• Active ocular disease in the operative eye other than cataract.
• Vulnerable subjects as defined in section 12.3.9.
• Corneal Astigmatism > 4.5 D
