Visual performance and subjective experience 3 and 12 months after combined implantation of 2 new complementary continuous phase multifocal IOLs.

Abstract

To assess the 3-month and 12-month postoperative visual performance and subjective quality of vision (QoV) after combined implantation of complementary continuous phase multifocal IOLs. Private Practice, United Kingdom. Case series. The study enrolled 44 patients undergoing phacoemulsification with implantation of an Artis Symbiose Mid (Cristalens, France) in the dominant eye and an Artis Symbiose Plus (Cristalens, France) in the nondominant eye. Refraction, uncorrected (UDVA) and best-corrected (CDVA) distance visual acuities, uncorrected intermediate (UIVA) and near (UNVA) visual acuities, electronic reading desk, and a QoV questionnaire were evaluated 3 and 12 months postoperatively. The mean binocular UDVA was -0.06 ± 0.08 logMAR and -0.07 ± 0.06 logMAR at 3 and 12 months (P=0.097). The mean binocular UIVA was 0.03 ± 0.13 logMAR and 0.03 ± 0.10 logMAR (P =1.0) respectively. Mean binocular UNVA was 0.07 ± 0.10 logMAR and 0.07 ± 0.08 logMAR, (P =0.875) respectively. There was a significant improvement in QoV for both day and night between 3 and 12 months, with a significant reduction in haloes at 12 months. Spectacle independence was reported in 93.2% of cases at 12 months. The Artis Symbiose Mid and Plus IOLs combined implantation provided an excellent range of unaided vision at 3 and 12 months. There was a significant improvement in QoV and less haloes at 12 months. This IOL combination provided very high rates of complete spectacle independence.
