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 a micro-monovision approach of emmetropia in the dominant eye and -1.0D to -1.5D in the non-dominant eye during cataract and refractive lens surgery.

Setting:

All MIOL implantations were performed at the Breyer-Kaymak-Klabe Augenchirurgie, Duesseldorf., Germany

Methods:

This prospective study comprises the results after bilateral implantation of new extended range of vision “MIOL” (ZXROO, Abott Medical Optics) in 40 eyes. Target refraction was emmetropia in the dominant eye and -1.5D in the nondominant eye. Postoperative examinations were performed for each eye seven days, binocular exams followed after 1 and 3 month after surgery. Subjective refraction (SR), defocus curve (DC), contrast sensitivity (CS), halos & glare assessment (HGA) and a patient questionnaire were evaluated.

Results:

The target refraction (+/- 0.5D SEQ) was achieved in all patients. Mean monocular UDVA in the emmetropic eyes of 20/20 or better through 1.5D of defocus could be found compared to an UDVA in the myopic targeted group 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). Binocular defocus with a VA of 20/40 or better was 2.5 D. CS was comparable to CS of phakic young patients at certain spatial frequencies. Photopsia like halos and glares were remarkably 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 a monovision approach the binocular function range of vision could be extended over more than 2.5 D.
