Abstract Details

Purpose:

The aim of this retrospective quality management investigation was to compare binocular visual outcomes between different variants of bilaterally implanted segmental MIOLs (Oculentis). Thereby we compared emmetropic vision with blended vision variants.

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). The Comfort with 1.5D addition was implanted in the dominant eye and in the non-dominant eye we implanted one of 4 MIOL variants.

Methods:

The 4 variants were (MIOL in the non-dominant eye): a) Comfort with 1.5D additon (200 patients), b) Comfort with 1.5D additon and -1.5D target refraction (75 patients), c) Comfort with 2.0D addition and -1.0D target refraction (25 patients), d) MplusX with 3.0D addition (25 patients). Results for subjective refraction and visual acuity were evaluated. Additionally, we analzyed binocular defocus curves and compared the area under these curves (MIOL-capacity) to those of phakic patients. Furthermore, we correlated monocular defocus curves to MTF-focus-through curves. Halo and glare was assessed with a computer based system. Contrast sensitivity was measured with the Ginsburg box.

Results:

Compared to phakic juvenile eyes, all 4 MIOL varaints showed binocular defocus capacities above 90% with variant b) achieving the hightest value: 105%. Mean binocular UDVA was <0.05LogMAR in all groups. After 3 months, photopsia were either absent or described as undisturbing. Contrast vision was better than in other bi- or trifocal MIOLs.

Conclusions:

MIOL-capacity showed results competitive to trifocal IOLs. The mixed implantation of two different refractive MIOL creates blended vision and seems to provide a new alternative to a diffractive trifocal IOL.
