Abstract Details

Purpose:

To evaluate the visual outcomes and quality of vision after implantation of a new aberration correcting extended depth of focus MIOL with emmetropia in the dominant eye and either a) 0.0D or b) -1.0D to -1.5D in the non-dominant eye (micro-monovision approach) during cataract and refractive lens surgery.

Setting:

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

Methods:

This prospective study comprises results after bilateral implantation of a new extended range of vision “MIOL” (ZXR00, Abott Medical Optics) in 36 eyes in group a) and 16 eyes in group b). Postoperative examinations were performed for each eye seven days, binocular exams followed 1 and 3 months after surgery. Manifest refraction, UDVA, defocus curves and MIOL-capacity, contrast sensitivity, halos & glare assessment and a patient questionnaire were evaluated.

Results:

The target refraction (+/- 0.5D SEQ) was achieved in all eyes. For emmetropic eyes, a mean monocular UDVA of 20/20 or better was found through 1.5D of defocus. For myopic eyes, mean UDVA was 20/40 or better. Binocular results: Patients reported to be almost glasses independent from driving a car to reading a newspaper or working at computer distance (70 cm). The MIOL-Capacity was above 95% in both groups. At certain spatial frequencies, contrast sensitivity was comparable to that of phakic juvenile patients. Photopsia like halos and glares were low and less compared to typical diffractive MIOLs.

Conclusions:

Considering life style aspects of most of our patients in case of a computer-based daily routine, as well as menage, handcraft or night driving, the new aberration correcting extended range of vision MIOL accomplishes patients’ needs better compared to the former diffractive generation. By using the monovision approach in variant b) the binocular function range of vision could be extended over more than 2.5D.
