    Background: The aim was to determine visual outcomes and patient satisfaction in patients undergoing cataract surgery after the binocular implant of multifocal difractive Intensity IOL Methods: 21 patients were evaluated. Six weeks after surgery, uncorrected distance visual acuity(UDVA), corrected distance visual acuity(CDVA), distance corrected intermediate visual acuity at 60 cm(DCIVA) and distance corrected near visual acuity at 40cm (DCNVA) were determined using the ETDRS test. Defocus curves were produced both in photopic and mesopic conditions. Contrast sensitivity(CSF) was measured using the CSV-1000 test. Patients were shown pictures about dysphotopic phenomena and informed about their meaning with a likert scale from 0 (no problem) to 4 (overwhelming). Results: Post implantation mean logMAR Binocular UDVA, CDVA, DCIVA and DCNVA were 0.07± 0.09, -0.01 ± 0.04, 0.08 ± 0.05 and 0.12 ± 0.06 respectively. Photopic defocus curve showed a extended range of good vision. Mesopic defocus curve results were better than previously reported with trifocal designs. Mean binocular CSF values for 4 spatial frequencies (3, 6, 12 and 18 cpd) were 1.55±0.29, 1.60±0.17, 1.29±0.26 and 0.81±0.15 log. units, respectively. Halos were more frequent than starburst and glare with a Likert scale mean value of 0.86±0.83. Conclusions: The IOL provided a continuous range of vision from distance to near. Patients were not bothered or only slightly bothered in relation to the visual disturbances.
