Impact of Glistenings in AcrySof Intraocular Lenses on Visual Quality
This study will assess the impact of IOL glistenings on visual quality and function in patients implanted with a single-piece AcrySof intraocular lens (IOL) that exhibits glistening formations. The primary objective is to determine if random light scattering (measured by C-Quant)correlates with severity of glistenings, other objective measures of visual function (visual acuity, low contrast visual acuity, low contrast visual acuity with glare), and subjective measures of patients' perceptions of their visual quality after cataract surgery (quality of life survey, reports of symptomology and satisfaction).

- Light scattering [ Time Frame: Post-opertative ] [ Designated as safety issue: No ]Correlation of random light scattering (measured with the C-Quant device) with severity of glistenings in the lenses
- Visual function [ Time Frame: Post-operative ] [ Designated as safety issue: No ]Correlation of visual function (visual acuity, contrast acuity and constrast acuity with glare)with glistening severity
- Visual quality [ Time Frame: Post-operative ] [ Designated as safety issue: No ]Correlation of visual quality (measured with quality of life questionnaire, and subjective reports of symptoms) with glistening severity
