Abstract Details

Purpose:

Due to different optical architectures the results of refractive MIOLs for contrast sensitivity, photopsia as well as visual acuity in intermediate distance improved significantly in comparison to classical diffractive bifocal MIOLs. The aim of this study was to compare visual outcomes between refractive MIOLs with different optical designs.

Setting:

All MIOL implantations were performed at the Breyer-Kaymak-Klabe Eyesurgery in Duesseldorf, Germany, which is part of the International Vision Correcton Research Center (IVCRC.net).

Methods:

We retrospectively analyzed the outcomes of the following groups: a) WIOL-CF (Medicem, continuous focus, no haptic, 16eyes) b) MiniWell (Sifi-Meditec, progressive multifocal, 20eyes) c) Comfort (Oculentis, segmental, +1.5D add., 500eyes) d) Comfort (Oculentis, segmental, +2.0D add., 50eyes) e) MplusX (Oculentis, segmental, +3.0D add., 50 eyes) Thereby, a-b) are rotationally symmetric, whereas c-e) are rotationally asymmetric. Results for manifest refraction and visual acuity were evaluated. Additionally, we analyzed defocus curves and compared the area under the curves (MIOL-capacity) to those of phakic juvenile patients. Halo and glare was assessed with a computer based system. Furthermore a patient questionnaire was evaluated.

Results:

Compared to phakic juvenile eyes, all 5 MIOLs showed corrected monocular defocus capacities above 70%. After 3 months mean monocular UDVA, in all groups was 0.1LogMAR. In cases of binocularity, there was a significant improvement in visual acuity in all distances. Halo and glare were either absent or desrcibed as undisturbing. The questionnaire revealed a high patient satisfaction with the quality of vision in the far, intermediate and near distance.

Conclusions:

Excellent visual outcomes can be provided by different refractive optical MIOL designs. MIOL-capacity in all groups showed results competitive to diffractive IOLs, whereas halo and glare take the backseat. The profile of the defocus curves can be used to meet individual patient needs.
