Clinical Investigation of the Next Generation Intraocular Lens

Clinical Investigation of the Safety and Effectiveness of the Next-Generation TECNIS® Symfony® Intraocular Lens Model ZHR00

An investigational IOL designed to provide improved intermediate and near visual acuity and decreased spectacle wear was evaluated for safety and effectiveness in a six-month study.

The next generation TECNIS IOL designed to provide improved intermediate and near visual acuity and decreased spectacle wear was evaluated for safety and effectiveness in a six-month interventional study and compared to a marketed monofocal IOL. Assessments included distance-corrected intermediate and near visual acuity, depth of focus at 0.2 logMAR and spectacle wear frequency.

Exclusion Criteria:

• Irregular corneal astigmatism
• Inability to focus or fixate for prolonged periods of time (e.g., due to strabismus, nystagmus, etc.)
