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.

Study Overview

• Status: Completed
• Conditions: Cataract
• Intervention / Treatment: Device: Investigational Intraocular Lens Device #1: Next Generation TECNIS IOL; Device: Control Monofocal Intraocular Lens: TECNIS Monofocal IOL

Detailed Description

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Monocular, Photopic Distance Corrected Intermediate Visual Acuity (DCIVA) at 66 Centimeter (cm)	Visual Acuity (VA) was assessed monocularly (each eye separately) under photopic (well-lit) conditions using best distance correction (distance refraction) and high contrast, Early Treatment Diabetic Retinopathy Study (ETDRS) chart at 66 cm from spectacle plane. It was measured in logarithm of the minimum angle of resolution (logMAR), on an ETDRS chart. A lower numeric value represented better VA. This analysis was pre-specified for the first operative eye only.	6 months (postoperative)
Monocular Photopic Distance Corrected Depth of Focus Assessed by the Mean Defocus Curve	Depth of focus was assessed using best corrected distance refraction, and 100% contrast ETDRS letters. VA was measured between +2.00 Diopter (D) and -4.00 D in 0.5 D defocus steps. VA was measured in logMAR. The depth of focus was estimated as the dioptric range between zero defocus and the first point on the negative lens induced mean defocus curve that crosses the 0.2 logMAR using a linear interpolation. A lower numeric value represents better VA. This analysis was pre-specified to be reported for the first operative eye only.	6 months (postoperative)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Monocular, Photopic Distance Corrected Near Visual Acuity (DCNVA) at 40 cm	Visual acuity was tested monocularly under photopic conditions using best distance correction (distance refraction) and high contrast, ETDRS chart set at 40 cm from the spectacle plane using the near point rod. VA was measured in logMAR on an ETDRS chart. A lower numeric value represented better VA. This analysis was pre-specified to be reported for the first operative eye only.	6 months (postoperative)
Overall Spectacle Wear	Overall spectacle wear was determined for participants wearing glasses or contact lenses using Patient-Reported Spectacle Independence Questionnaire (PRSIQv2) asking if their response is 'none of the time' in all the 4 conditions (distance vision, intermediate vision, near vision and overall vision) of the spectacle wear questions were reported. PRSIQv2 questionnaire responses were divided into two response groups: reports of "none of the time" and the combined reports of "a little of the time," "some of the time," "most of the time," or "all of the time".	6 months (postoperative)
