To compare the functional outcomes after implantation of multifocal intraocular lenses (IOLs) with a +2.50, +3.00 and +3.75 diopter (D) addition power.
Istanbul Medipol University
90 eyes of 45 patients who underwent cataract surgery or refractive lens exchange and multifocal IOL implantation with at least 6-month follow-up were included in the study. 30 eyes had hybrid diffractive/refractive +2.50 add IOL, 30 eyes had hybrid diffractive/refractive +3.00 D add IOL, and 30 eyes of 15 patients full diffractive +3.75 D add IOL. Visual acuities for distance, intermediate, and near vision at 32 cm, 40 cm, 50 cm, and 60 cm, contrast sensitivity under photopic, mesopic, and mesopic with glare, spherical and astigmatic defocus, spectacle dependance, patient reported satisfaction, and patient reported visual disturbances were evaluated.
All three IOL groups provided good distance vision. +2.50 D group tend to have better intermediate vision than +3.00 D and +3.75 D group. Hybrid design multifocal IOLs tend to have worse intermediate and near vision at low light levels. +2.50 D group had better spherical and astigmatic defocus tolerability. 10 (66%) of 15 patients in +2.50 group, 2 (13.3%) of patient in +3.00 group, and none in +3.75 group reported using of spectacles for near. Although all IOL groups reported minimal visual disturbances, the +2.50 group had the least followed by +3.00 group and +3.75 group.
Eyes with different types of multifocal IOLs have good distance, intermediate, and near vision that these IOLs designed for. Therefore their implantation should be customized depending on patients needs and expectations.
