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

A Prospective, Multicenter Clinical Study Comparing Outcomes of Two Trifocal Toric Intraocular Lens

To evaluate the clinical outcomes and patient satisfaction of two commercially available trifocal toric intraocular lenses Primary Objective: To compare the distance-corrected intermediate visual acuity between the two trifocal toric intraocular lenses. Secondary Objectives: To assess and compare the safety of two trifocal toric intraocular lenses.

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.

7. Subjects with any systemic disease that could increase operative risk or confound the outcome.
8. Active ocular disease in the operative eye other than cataract.
9. Vulnerable subjects as defined in section 12.3.9.
10. Corneal Astigmatism > 4.5 D
