Bilateral implantation of the Acri.LISA 366D distance-dominant bifocal intraocular lens provides a satisfactory full range of vision.
Bilateral implantation of the Acri.LISA 366D distance-dominant bifocal intraocular lens (IOL) provides a satisfactory full range of vision, according to the results of a study published in the November issue of the Journal of Cataract and Refractive Surgery.
José Alfonso and colleagues from the Fernández-Vega Ophthalmological Institute, Oviedo, Spain bilaterally implanted the Acri.LISA 366D IOL in 81 patients. Monocular and binocular best corrected visual acuity and best distance corrected near visual acuity, binocular best distance corrected intermediate visual acuity and distance contrast sensitivity under photopic and mesopic conditions were determined.
At three months follow-up, the mean binocular best corrected distance visual acuity was 0.048±0.111 logMAR and the mean binocular best distance corrected near acuity was 0.012±0.0084 logMAR. The mean binocular best distance corrected intermediate acuity changed significantly as a function of the distance of the test from 0.012±0.084 logMAR at 33 cm to 0.265±0.099 logMAR at 70 cm (p<0.01). Contrast sensitivity was within normal limits under photopic and mesopic conditions.
These results demonstrate that the Acri.LISA 366D IOL offers a good full range of vision.
