This trial is active, not recruiting.
|Treatment||at lisa tri 839mp|
|Sponsor||Carl Zeiss Meditec AG|
|Start date||January 2012|
|End date||January 2014|
|Trial size||120 participants|
|Trial identifier||NCT01731743, 839 MP HEN 402-11|
The purpose of the study is to evaluate the far, intermediate and near visual acuities with a trifocal IOL.
|Endpoint classification||safety/efficacy study|
|Intervention model||single group assignment|
Intermediate visual acuity
time frame: up to 3 months postoperatively
near and far visual acuity
time frame: 1 and 3 month postoperatively
Male or female participants at least 50 years old.
Inclusion Criteria: - Man or woman, over 50 years of age - Bilateral implantation of a trifocal intraocular lens - Capsular bag implantation Exclusion Criteria: - Existing ocular pathology - Surgical complications - Corneal astigmatism ≥ 1.0D
|Description||After bilateral cataract surgery, monocular and binocular uncorrected (UCVA) and best distance corrected visual acuity (BCVA) will be measured at far (4m), intermediate (80 cm) and near (40 cm) distance as well as the subjective refraction. A patient questionnaire will be used to assess the patient satisfaction and spectacle independence.|
