Abstract Details

Purpose:

To analyze the long-time longitudinal change in light scattering caused by glistenings in Acrysof® intraocular lenses (IOL), and the clinical implications on high and low constrast visual acuity.

Setting:

Eye clinic, Department of Clinical Sciences/Ophthalmology, Umeå University, Sweden.

Methods:

A total of 90 individuals, 31 males and 59 females, were included in the study. All patients had a MA60BM Acrysof® IOL implanted at phacoemulsification surgery in 1997-98. Light scattering from the IOL was analysed by digital analysis of Scheimpflug photographies (Pentacam® HR) from both the 10- and 15-year follow-up. A subgroup of 71 patients, without coexisting ocular pathology was selected for the visual function analysis. Associations were made with best corrected visual acuity (BCVA) as well as low contrast visual acuity (LCVA) 10% and 2.5%, and the degree of light scattering from the IOL.

Results:

The majority of patients had increased light scattering caused by glistenings at 15 years, compared with 10 years after surgery. The patients were divided into various groups according to the degree of light scattering. It was not possible to detect any significant decrease in visual function, measured as BCVA and LCVA 10% and 2.5%, in eyes with a more pronounced light scattering of the IOL compared with eyes with less light scattering.

Conclusions:

Glistenings continue to increase in Acrysof® IOLs from 10 to 15 years after surgery. At 15 years after surgery most patients in this cataract surgery case series had severe glistenings with a high level of light scattering from their IOLs. Even though, there was no clinically significant impact on visual function, as measured in the present study (BCVA and LCVA 10 and 2.5%).
