Purpose: First functional results of the bifocal refractive IOL with a newly constructed optical zone (the upper part for far and the lower part for near vision) independent on the size of pupil are presented.

Methods: A prospective study was organized in 25 healthy patients with cataracts of age 66, SD=11. Standard phaco cataract surgery was used - it means: 12 o'clock 2.5 mm limbal incizion, combination of dispersive and cohesive viscomaterials for 4.5mm capsulorhexis, coaxial „chop and stop“ phacoemulsification with Infiniti or Millenium, biaxial irrigation and aspiration with additional LEC aspiration using 5-hole canule and IOL implantation into the bag under cohesive viscomaterial using Medicel injector and cartridge of 2.2 mm, a horizontal positioning of marks on the IOL using biaxial I/A instruments and hydratation of side ports with Axetine. UCVA and BCVA using ETDRS charts for 6m, 40cm and 80cm, Pelli Robson Contrast Sensitivity Test (PRCST) and CSV1000 2.4 m were measured 3months after surgery.

Results: Functional results-average(SD): UCVA far increased from 0.34 (0.22) to 1.04 (0.24). BCVA increased from 0.56 (0.24) to 1.15 (0.19). UCVA 40 cm was 0.92 (0.17), BCVA 40 cm was 1.05 (0.15) with +0.88D (SD=0.2) after 3 weeks. UCVA 80 cm was 0.42 (0.09). PRCST increased from 1.35 to 1.85 (0.13), CSV1000 was of the norm (A=5.3, B=6.5, C=6.9, D=7.2) after 3 months. Good perception of far and near vision was excellent in first days after surgery. Low frequence of the accesory light phenomenons (hallo, glare) was recorded.

Conclusions: New bifocal refractive IOL has a hopeful early visual acuity without substantial loss of contrast sensitivity. It has fast individual adaptation and less light phenomenons.
