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 Intervention/treatment
Experimental: 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.
 Device: Tecnis ZLB00 & Symfony IOL
The Symfony IOL will be implanted in the dominant eye while the Tecnis ZLB00 will be implanted in the non-dominant eye.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Binocular distance-corrected near (40 cm) visual acuity. [ Time Frame: 1 month ]
    Visual acuity measured at 40 cm using the distance-correction if needed.

  2. Binocular distance-corrected near (40 cm) visual acuity. [ Time Frame: 3 months ]
    Visual acuity measured at 40 cm using the distance-correction if needed.


Secondary Outcome Measures :
  1. Patient visual satisfaction after cataract surgery: questionnaire [ Time Frame: 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". Possible answers are: Completely satisfied, mostly satisfied, moderately satisfied, a little satisfied, not at all satisfied.

  2. Spectacle independence: questionnaire [ Time Frame: 3 months ]
    Patient's spectacle independence will be 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. Possible answers: Yes No. 2. During the LAST 7 DAYS, how often did you wear glasses or contacts and 3. During the LAST 7 DAYS, were you able to function comfortably WITHOUT glasses or contacts. Questions 2 and 3 possible answers are: All of the time, Most of the time, Some of the time, A little of the time, None of the time

  3. Visual symptoms [ Time Frame: 3 months ]
    Patient's reported visual symptoms
