Micro Monovision With A New Enhanced Monofocal Iol: Results After Bilateral Implantation In 50 Patients

To evaluate the binocular distance and intermediate visual acuity and quality of scotopic visual aquitiy of cataract patients after bilateral implantation of an enhanced monofocal IOL(RayONE EMV, Rayner) in a micro monovision approach.

We retrospectively analyzed four weeks after bilateral Implantation of the RayONE EMV IOL in cataract patients. All patients showed no relevant macular degeneration or corneal pathologies preoperatively. In Patients with corneal astigmatism above 0,75 dpt a toric IOL was used. Target refraction was in the dominant eye emmetropia and in the fellow eye -0.5 dpt. The surgery was performed by a single surgeon. Four weeks postoperatively among other  results uncorrected binocular distance visual acuity and intermediate visual acuity and corrected distance visual acuity was examined. Regarding halo and glare symptoms the Halo  and Glare simulator was used.

Mean age of the patients was 74 years. Mean sphere was +2.0dpt (range -0.75 to 5,5dpt) and mean cylinder 1,0 (range 0,0 to 1,75dpt) Corrected distance visual acuity improved from 0,6 logMar to 0,0 LogMar. Binocular UCDVA postoperatively was 0.1 LogMar and binocular UCIVA 0.3LogMar. No intra- and postoperative complications occoured. No patient complained about increased photopic phenomena. The halo and glare Simulator showed in all patients  low values below 10 (0-100 possible).

The RayONE EMV showed good results regarding improvement of uncorrected DVA in cataract patients. The uncorrected IVA was satisfying and allowed the patients to read newspaper print in intermediate distance and good light conditions. Spectacle independence in daily life significantly increased. The quality of night vision was very satisfying in all patients.
