Abstract Details

Purpose:

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.

Setting:

Breyer Kaymak Augenchirurgie

Methods:

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.

Results:

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.

Conclusions:

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
