Tecnis ZLB00 & Symfony Intraocular Lens Combination Outcomes

Not Applicable

Completed

• Conditions: Presbyopia; Cataract Bilateral
• Interventions: Device: Tecnis ZLB00 & Symfony IOL

• Registration Number: NCT03771274
• Lead Sponsor: Carolina Eyecare Physicians, LLC

Brief Summary

Current visual outcomes expectations of cataract patients are similar to those of refractive surgery patients. Their desire is to be spectacle independent for far, intermediate and near vision activities. Some may have already enjoyed freedom from glasses and would like to continue after the cataracts are removed. Different options are available. These options include: mono-vision and presbyopia correcting intraocular lenses (IOL). Presbyopia correcting IOLs include accommodative, multifocals and extended depth of focus (EDOF) IOLs. In a previous study, the visual outcomes of the EDOF Toric IOL were evaluated when both eyes were targeted for plano and when the non-dominant eye was set for a small residual myopic error (-0.50 D) or nanovision in patients with astigmatism. The nanovision approach, appeared to provide similar binocular acuity at distance and intermediate but better acuity at near. The purpose of this study is to evaluate the visual outcomes of an EDOF IOL when combined with a multifocal IOL with a +3.25 D add in patients with or without astigmatism undergoing routine cataract surgery.

Arm && Interventions

Group	Intervention	Description
Tecnis ZLB00 & Symfony IOL	Tecnis ZLB00 & Symfony IOL	The Tecnis multifocal ZLB00 and the Symfony IOLs are presbyopia correcting lenses designed to improve the vision at distance, intermediate and near reducing the need for glasses in patients undergoing cataract surgery.

Primary Outcome Measures

Name	Time	Method
Binocular Uncorrected Near (40 cm) Visual Acuity.	3 months	Visual acuity measured at 40 cm without wearing any correction.

Secondary Outcome Measures

Name	Time	Method
Patient Visual Satisfaction After Cataract Surgery: Questionnaire	3 months	Patient's overall satisfaction with their vision after cataract surgery assessed by asking the following question: "Taking all things into account, how satisfied or dissatisfied are you with your vision WITHOUT glasses or contacts with your near vision". Possible answers are: Completely satisfied and mostly satisfied, moderately satisfied, a little satisfied or not at all satisfied.
Spectacle Independence: Questionnaire	3 months	Patient's spectacle independence was assessed using the "Patient Reported Spectacle Independence Questionnaire (PRSIQ) which includes the following questions: 1. During the LAST 7 DAYS, did you need glasses or contacts for near. Possible answers: Yes No.
Number of Participants With Visual Symptoms	3 months	Number of participants who reported any visual disturbances or symptoms. One participant could report more than one symptom.
