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

Purpose: 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 intraocular lenses (IOLs). Setting: Private practice, United Kingdom. Design: Case series. Methods: The study enrolled 44 patients undergoing phacoemulsification with implantation of an Artis Symbiose Mid in the dominant eye and an Artis Symbiose Plus in the nondominant eye. Refraction, uncorrected distance visual acuity (UDVA), corrected distance visual acuity, uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), electronic reading desk, and a QoV questionnaire were evaluated at 3 months and 12 months postoperatively. Results: The mean binocular UDVA was −0.06 ± 0.08 logMAR and −0.07 ± 0.06 logMAR at 3 months and 12 months ( P = .097), respectively. The mean binocular UIVA was 0.03 ± 0.13 logMAR and 0.03 ± 0.10 logMAR ( P = 1.0), respectively. The mean binocular UNVA was 0.07 ± 0.10 logMAR and 0.07 ± 0.08 logMAR ( P = .875), respectively. There was a significant improvement in QoV for both day and night between 3 and 12 months, with a significant reduction in halos at 12 months. Spectacle independence was reported in 93.2% of cases at 12 months. Conclusions: The Artis Symbiose Mid and Plus IOL combined implantation provided an excellent range of uncorrected vision at 3 and 12 months. There was a significant improvement in QoV and less halos at 12 months. This IOL combination provided very high rates of complete spectacle independence.
