Visual Outcomes And Patient Satisfaction 1 And 6 Months After Combined Implantation Of New Complementary Multifocal Intraocular Lenses

To outline the early 1 month and 6 month postoperative visual and refractive outcomes and quality of vision (QoV) after combined implantation of complementary continuous phase multifocal intraocular lenses (IOLs).

Cathedral Eye Clinic, Belfast, Northern Ireland, UK

Forty patients undergoing refractive lens exchange with an Artis Symbiose Mid (Cristalens, France) in the dominant eye and a Artis Symbiose Plus in the nondominant eye were recruited. Refraction, uncorrected (UDVA) and best-corrected (CDVA) distance visual acuities, uncorrected intermediate (UIVA) and near (UNVA) visual acuities, defocus curves and a QoV questionnaire were evaluated 1 and 6 months postoperatively. 

The mean binocular UDVA, UIVA and UNVA were -0.06 ± 0.07 logMAR, 0.06 ± 0.11 and 0.07 ± 0.10 logMAR respectively, 1 month postoperatively. There was no significant difference between the 1 and 6 months assessments for binocular unaided vision. QoV scores during the day were 8.80 ± 0.94 and at night the reported QoV was 7.53 ± 1.22 at 1 month. There was no significant difference between the 1 and 6 month QoV scores, however higher values were reported for both day and night at 6 months. Spectacle independence was reported by 97.5% of patients.

This new complementary combined IOL implantation demonstrated an excellent range of unaided vision, and high subjective patient satisfaction, however some early visual side effects were reported. Objective visual outcomes and QoV appear to remain stable in this early postoperative period. Further long term follow up is required.
