Abstract Details

Purpose:

A prospective study to evaluate refractive and functional results after implantation of an EDoF intraocular lens combined with a multifocal intraocular lens (Mix&Match) compared to bilateral implantation of an aspheric, rotationally asymmetric intraocular lens with increased depth of focus  (EDoF) in older cataract patients.

Setting:

Augentagesklinik Rheine, Germany

Methods:

In a prospective, ongoing study a total of 42 eyes were examined after uncomplicated cataract surgery.  In 24 eyes, an aspheric, rotationally asymmetric EDoF-IOL (LENTIS LS-313 MF15, Oculentis) was implanted bilateral. 9 patients received an EDoF-IOL (LENTIS LS-313 MF15, Oculentis) in their distant dominant eye and a multifocal IOL (LENTIS LS-313 MF30, Oculentis) in their near dominant eye. Target refraction was emmetropia in all eyes. The UDVA & DCVA (4m), UNVA & DCNVA (40cm), DCIVA (90cm, 80cm, 60cm), defocus curve, optical imaging quality with the HD Analyzer and photic phenomena with the Halo & Glare Simulator have been evaluated.

Results:

MF15 Group: SE bilateral:+0.15dpt [ +/-0.49]. Binocular/monocular defocus curve:visual acuity of < 0.2 logMAR in the range of +1.0 to -1.5 dpt Halo&Glare:72% of the patients described no light phenomena, 21% mild and 7% moderate MTF cut off:12.51 c/deg to 49.22 c/deg Strehl ratio:0.09 to 0.23 Mix & Match group: SE MF15:-0.25 dpt [+/-0.35] SE MF30:-0.25 dpt [+/-1.59] Monocular/binocular defocus curve:visual acuity of < 0.4 logMAR in the range of +1.00 to -1.50 dpt Halo&Glare:67% of the patients perceive mild light phenomena and 33% moderate MTF cut off:15.62 c/deg to 20.12 c/deg Strehl Ratio:0.09 to 0.118

Conclusions:

The Mix & Match combination showed a significantly higher degree of eyeglass independence in the near distance compared to the results of the bilateral implantation of the EDOF intraocular lens while providing better results in the intermediate range. The aspherical, rotationally asymmetric intraocular lens achieves good distance visual acuity with a good intermediate visual acuity of up to 60 cm. With regard to patient satisfaction, 79% would choose one of these intraocular lenses again. A high level of patient satisfaction can be observed in both groups.
