Abstract Details

Purpose:

To demonstrate visual performance of the IC-8 small aperture IOL (AcuFocus, Irvine, CA) implanted in patients in whom a cataractous lens has been removed. To demonstrate that IC8 IOL technology is not comparable with monovision. To prove that up to 2 diopters of astigmatism pinhole effect avoid the need of toric correction IOLs.

Setting:

C.M.A. Centro Microchirurgia Ambulatoriale Monza – Italy

Methods:

22 cataract patients with corneal astigmatism ≤ 1.25, received an IC-8 IOL in the non-dominant eye and an aspheric monofocal IOL in the dominant eye. Three patients received bilateral IC8 implants. Regular follow-up examinations were performed up to 2 years after surgery, measuring the following parameters: distance (UDVA, 4m) near (UNVA, 40cm) and intermediate (UIVA, 70 cm) visual acuity, corneal topography and Acutarget analysis, contrast sensitivity , Hemifield Test and defocus curve

Results:

At 3 years in the IC-8 eye, UDVA was 20/22 ± 2.64, UIVA 20/27 ± 12.39 and UNVA 20/26 ± 6.39. In the monofocal eye, UDVA was 20/19 ± 1.33, UIVA 20/31 ± 9.93 and UNVA 20/64 ± 21.54. Binocular UDVA was 20/19 ± 1.51, UIVA was 20/24 ± 4.93 and UNVA 20/27 ± 3.83

Conclusions:

The IC-8 showed excellent visual performance at 2 years. IC-8 in the dominated eye, combined with best technology aspheric monofocal IOL in the dominant eye provided excellent binocular distance vision. Intermediate and near vision is provided and there is no need to wear presbyopic glasses .IC-8 implant does not require to add toric correction up to 2 diopters of astigmatism. The pinhole effect takes care of visual performances.
