Abstract Details


Due to different optical architecture of current available MIOL results of contrast sensitivity, photopsia as well as visual acuity in intermediate distance vary sometimes remarkably. We present a comparative MIOL profile based on classic refractive outcome as well as defocus capacity and contrast sensitivity compared to phakic juvenile eyes by comparing two different refractive MIOL with a different near addition.

We analyzed retrospectively patients after implantation of either MIOL with an addition of +3.0 D or an addition of +1.5 D (Oculentis). Results of subjective refraction as well as visual acuity at far, intermediate and near distance were collected. Additionally we analzyed the binocular defocus curves between 33 cm (-3.0 D) and infinity (0.0 D) and compared the area under the respective curves to those of phakic juvenile patients of our patient population as well to other current MIOL.


Overall defocus capacity was comparable between both MIOL but with different VA peaks at distinct distances. Compared to phakic eyes, both MIOL showed a defocus capacity of minimal 75% up to 84% (mixed implantation : Add. +1.5 on one eye, Add.+3.0 other eye). Photopsia were in most cases absent after three month, 2 patient reported of residual halos with a low intensity.


Defocus capacity showed best results with a mix of both analyzed MIOL with an Add. +1.5 and +3.0 and is competitive to a trifocal IOL, which showed a defocus capacity of 82% compared to phakic eyes (100%). The mixed implantation of two different refractive MIOL seems to provide a competitive alternative to a diffractive trifocal IOL. FINANCIAL INTEREST: NONE
