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.

Setting:

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

Methods:

21 Eyes with cataract, corneal astigmatism ≤ 1.25, had IC-8 IOL implantation in the non-dominant eye and an aspheric monofocal IOL in the dominant eye. Postoperatively, the following visual and refractive parameters were measured: distance (4m) near (40cm) and intermediate (80 cm) visual acuity, corneal topography and Acutarget analysis, contrast sensitivity and defocus curve. Regular follow-up examinations were performed up to 3 years after surgery. For the last follow up an additional examination of intermediate (67 cm) visual acuity was added.

Results:

At 3 years in the IC-8 eye, UDVA is 20/20.5 , UIVA is 20/19 at 80cm and 67 cm and UNVA is 20/20.5 . In the monofocal eye, UDVA is 20/19, UIVA is 20/23 at 80 cm 20/25.7 at 67 cm and UNVA is 20/50. Binocular UDVA is 20/18, UIVA is 20/18.3 (80 cm and 67cm) and UNVA is 20/20.5 .

Conclusions:

Pinhole technology in the non dominant eye mixed with advanced monofocal IOL in the dominant eye provides good far, intermediate and near vision . Minimum distance vision with IC8 IOL was 20/25 so pinhole technology could not be included in the monovision family. Pinhole effect normally corrects up to two diopters of corneal astigmatism. This means that 85% of astigmatic patients implanted with IC8 does not require any specific technology or management related toric IOLs positioning.
