Abstract Details

Purpose:

The purpose of this retrospective consecutive cohort study is to compare the monocular (non-dominant eye) visual outcomes between KAMRA corneal inlay (Acufocus, Inc., Irvine, CA) implantation in pseudophakic patients, extended-depth-of-focus lens (EDOF-IOL) TECNIS Symfony intraocular lens (Abbott Medical Optics, Santa Ana, California, USA) and diffractive multifocal intraocular lens (MF-IOL) Acrysof IQ ReSTOR +3.0 D (Alcon Laboratories, Forth Worth, Texas, USA).

Setting:

Department of Ophthalmology, Saarland University Medical Hospitals, Homburg/Saar, Germany. Institute of Experimental Ophthalmology, Saarland University, Homburg/Saar, Germany.

Methods:

Ten patients underwent cataract surgery (n=2) or refractive lens exchange (RLE) (n=8) with monofocal IOL implantation and 6 weeks later KAMRA inlay implantation in the non-dominant eye (KAMRA group). Eleven patients had bilateral cataract surgery (n=2) or RLE (n=9) with EDOF-IOL (Symfony group) implantation. Nine patients had bilateral cataract surgery (n=7) or RLE (n=2) and implantation of Acrysof IQ ReSTOR +3.0 (MF group). Non-dominant eye of all patients was targeted for a micro-monovision (-0.5 D). The monocular (non-dominant eye) corrected distance (CDVA), uncorrected distance (UDVA), uncorrected intermediate (UIVA) and uncorrected near visual acuities (UNVA) were compared pre- and 3-months postoperatively.

Results:

All patients were available for the 3-month postoperative examination. The KAMRA group demonstrated improved mean UDVA from 20/50 to 20/20, mean UIVA was Jaeger (J) 1 with 10 lines gained and mean UNVA was J1 with 9 lines gained. The preoperative CDVA was 20/22. The Symfony group had a mean monocular UDVA improvement from 20/50 to 20/25, mean UIVA was J2 with 10 lines gained and mean UNVA was J3 with 7 lines gained. The preoperative CDVA was 20/22. The MF group achieved a mean monocular UDVA improvement from 20/100 to 20/30, mean UIVA was J4 with 6 lines gained and mean UNVA was J2 with 8 lines gained. The preoperative CDVA was 20/25.

Conclusions:

The KAMRA corneal inlay in pseudophakic patients was superior in the three distances when compared to the Symfony and MF group. The KAMRA group gained 1 line comparing the postoperative UDVA with the preoperative CDVA, whereas the Symfony and multifocal group lost 1 line. The MF group was better in the mean UNVA, but worse in the mean UIVA compared to the Symfony group. The KAMRA corneal inlay in pseudophakic patients seems to be an effective and safe method for the surgical correction of presbyopia in well selected patients.
