Abstract Details


To clinically evaluate a 'Blended Vision' approach to AcrySof® IQ ReSTOR® implantation, using a +2.5D lens in one eye and a +3.0D lens in the other. In addition, to compare the performance of this 'Blended Vision' option to available data from bilateral ReSTOR +2.5 and bilateral ReSTOR +3.0 patients who were previously treated at the same site.


Single surgeon clinic


Post-operative visual acuity and quality of vision data were recorded from patients who had previous implantation of an AcrySof® IQ ReSTOR® +2.5D lens in one eye and +3.0D lens in the other. Uncorrected and best distance-corrected visual acuity at distance (4m), intermediate (60cm) and near (40cm), as well as low contrast acuity at 4m, were measured. Each patient's preferred reading distance was recorded, along with the visual acuity at that distance; acuities were appropriately adjusted for changes in chart distance. Quality of vision metrics were also collected. Data from these patients were compared to available data from a previous study that included patients implanted bilaterally with either the ReSTOR +2.5D or ReSTOR +3.0 D lenses.


Data from a total of 21 Blended Vision patients were collected. Refractive outcomes showed excellent predictability with 93% of eyes within 0.5D of the target refraction. Uncorrected binocular distance visual acuity was better than 0.1 logMAR (0.8 decimal acuity) in 95% of patients. Best distance-corrected VA was equivalent to the binocular +2.5 patients at intermediate and equivalent to the binocular +3.0 patients at near. Binocular distance low contrast acuity was similar to that of the binocular +2.5 patients. Reading distance was similar to the binocular +3.0 patients and all Blended Vision patients had 0.2 logMAR (0.67 decimal) or better VA at their preferred reading distance.


Blended Vision with the ReSTOR +2.5/+3.0 appears to provide patients with the advantages of both lenses, rather than a compromise between the binocular +2.5 and binocular +3.0 options. FINANCIAL INTEREST: NONE
