Clinical Data on the AcrySof® IQ ReSTOR® IOL
Results from studies on visual acuity, visual disturbances and patient satisfaction.
Binocular Visual Acuity
A full range of clear vision – near, intermediate and far.
The vast majority of patients who undergo cataract surgery receive monofocal IOLs. While these lenses may successfully correct distance vision, they do not provide functional near vision. This means that patients must continue to wear reading glasses or bifocals to perform routine daily tasks like reading a newspaper, menu or medicine bottle.
Fortunately, clinical studies clearly demonstrate the excellent visual performance of the AcrySof® IQ ReSTOR® IOL, which can offer patients clear vision at all distances.
Distance Visual Acuity
Studies show that the AcrySof® IQ ReSTOR® IOL +3.0 D provides excellent near visual acuity without compromising distance vison. In a recent study, 99% of patients who received the AcrySof® IQ ReSTOR® IOL +3.0 D bilaterally achieved distance visual acuity of 20/40 or better without correction.1
Additionally, 85% of patients who received the AcrySof® IQ ReSTOR® IOL +3.0 D bilaterally achieved distance visual acuity of 20/25 or better without contacts or glasses. In the original AcrySof® ReSTOR® IOL study, 88% of patients who received the AcrySof® ReSTOR® IOL bilaterally achieved uncorrected distance visual acuity of 20/25 or better compared to 92% of monofocal lens wearers, indicating that the two lenses are statistically equivalent in distance visual acuity.1
Near Visual Acuity
75% of patients who received the AcrySof® IQ ReSTOR® IOL +3.0 D bilaterally achieved near visual acuity of 20/25 or better without correction. In the original AcrySof® ReSTOR® IOL study, 70% of patients who received the AcrySof® ReSTOR® IOL bilaterally achieved near visual acuity of 20/25 or better compared to only 14% of a monofocal control group.1
Additionally, clinical studies show that the new AcrySof® IQ ReSTOR® IOL +3.0 D increases the distance of best near visual acuity by 20%, or about 2.5 inches, compared to the +4.0 D model.1
Intermediate Visual Acuity
According to the clinical studies, the AcrySof® IQ ReSTOR® IOL +3.0 D model also provides patients with an even fuller range of excellent intermediate vision. The studies show that the near to intermediate range of visual acuity has more than doubled, from 5 to 11 inches, with the +3.0 D IOL.1
90% of AcrySof® IQ ReSTOR® IOL patients achieved functional uncorrected intermediate vision of 20/40 at 60 cm.
With overall visual acuity of 20/32 for all distances† and an improved apodized diffractive optic design, the AcrySof® IQ ReSTOR® IOL +3.0 D gives your patients a better chance than ever for a fully restored range of vision – near, intermediate and distance.1
Visual Disturbances
The AcrySof® IQ ReSTOR® lens features a patented technology called apodization. The process of apodization involves the gradual tapering of concentric step heights from the center to the periphery of a lens's diffractive region. Apodization creates a smooth transition of light between the distance, intermediate and near focal points, reducing the potential for glare, halos and other visual disturbances.
According to the clinical study, all mean visual disturbance ratings were within the None/Mild category (less than 3 on a scale of 0 to 7) in patients with the AcrySof® IQ ReSTOR® IOL +3.0 D. The study also demonstrated no clinically relevant increase of severe visual disturbances compared to the +4.0 D model.
Quality of Life
In a patient satisfaction survey, the majority of patients implanted with the +3.0 D IOL – nearly 94% – indicated that they would have the lenses implanted again.1
