To assess the visual results after implantation of the bifocal Acri.LISA 356D intraocular lens (IOL).

Material and Method:

Thirty-three eyes of 26 patients who had undergone cataract extraction by phacoemulsification technique were implanted with Acri.LISA 356 D IOL. All eyes were tested both at far and near distance at mesopic and photopic room light levels (5 and 85 cd/m2), in the following 1st and 3rd months after the operation. All eyes were tested for far, intermediate and near visual acuity, contrast sensitivity, refractive errors, glare and visual complaints, and need for spectacles.


The mean age of the patients was 58.2±9.3 years. Out of the 26 patients who participated in the study, nineteen (8 female, 11 male) had unilateral and 7 patients (5 female, 2 male) had bilateral implantation. At 3-month postoperative visit, the mean best-corrected distance visual acuity was 0.94±0.08, the best distance-corrected near visual acuity was 0.77±0.12 and the best distance-corrected intermediate (70cm.) visual acuity was 0.67±0.10. Distance visual acuity was significantly better than intermediate and near visual acuities, while near visual acuity was statistically significantly better than intermediate visual acuity (p<0.05 for each). Postoperative mean spherical equivalent was -0.85±0.55 D. At 1 month, contrast sensitivity was low, especially at near under both illumination levels and, at 3 months, low contrast sensitivity level persisted at near under mesopic conditions only at high spatial frequencies. The incidence of halos was higher in patients with higher astigmatism. Although it seemed that 74% of patients needed eyeglasses for far, the rate of using eyeglasses was only 15%.


The Acri.LISA 356D, which is a bifocal hybrid IOL, provided satisfaction for far/near visual acuity and contrast sensitivity under photopic and mesopic conditions. However, it is not successful at the same degree for intermediate distances. (Turk J Ophthalmol 2011; 41: 236-42)
