Purpose: To evaluate the efficacy and safety of a newly developed diffractive multifocal intraocular lens (IOL) with +2.5 diopter near add power (SN6AD2, Alcon), whose theoretical distance for near focus is 50 cm.
Methods: This study included 128 eyes of 64 patients (23 men and 41 women, average age: 66.7±7.2 years) following cataract removal at Tokyo Dental College Suidobashi Hospital and Hayashi Eye Hospital. Visual acuities (VAs) at distance, 1 m, 50 cm and 40 cm, and questionnaires were evaluated until 1 year postoperatively.
Results: At 1 year postoperatively, mean bilateral logMAR VAs were uncorrected -0.09 (5 m), 0.01 (1 m), 0.07 (50 cm), 0.18 (40 cm), distance corrected 0.01 (1 m), 0.08 (50 cm), 0.19 (40 cm), best corrected -0.17 (5 m), 0.00 (50 cm). From the patient's questionnaires, light or moderate glare was noticed in 17.5%, 4.8%, light or moderate halo was notice in 19.0%, 4.8% of the total patients.
Conclusion: This IOL provides good distance to intermediate VAs and better near VA compared to monofocal IOL
