BACKGROUND: Visual acuity, visual functioning, and vision related quality of life outcomes after @entity231 surgery were assessed in a population based study in a suburban area of Hong Kong. METHODS: A cluster sampling design was used to select apartment buildings within housing estates for enumeration. All enumerated residents 60 years of age or over were invited for an eye examination and visual acuity measurement at a site within each estate. @entity227 ( @entity227 ) and vision related quality of life (QOL) questionnaires were administered to interview subjects who had undergone @entity231 surgery and to unoperated @entity1 with presenting visual acuity less than 6/60 in either eye, and a sample of those with normal visual acuity. RESULTS: 36.6% of the 310 @entity231 operated individuals had presenting visual acuity 6/18 or better in both eyes, and 40.0% when measured by pinhole. 4.5% were blind, with presenting visual acuity less than 6/60 in both eyes. Of operated eyes, 59.6% presented with visual acuity 6/18 or better. 11.2% of the operated eyes were blind with vision less than 6/60. Visual acuity outcomes 6/18 or better were marginally associated with surgery in private versus public hospitals. Lens status (pseudophakic versus aphakic) and surgical period (within the most recent 3 years versus before) were not significantly related to vision outcomes. Mean @entity227 and QOL scores decreased consistently with decreasing vision status. Spearman correlation with vision status was 0.420 for @entity227 scores and 0.313 for QOL scores. Among @entity227 /QOL subscales, correlation was strongest for visual perception (r = 0.447) among @entity227 subscales and weakest for self care (r = 0.171) among QOL subscales. Regression adjusted @entity227 and QOL total scores for @entity231 operated individuals were slightly lower than for those of visually comparable unoperated individuals (p<0.05). CONCLUSIONS: @entity231 operations in Hong Kong did not consistently produce good presenting visual acuity outcomes, suggesting that postoperative monitoring would be useful to minimise @entity227 in this population. Although vision outcomes were consistently correlated with all @entity227 /QOL subscale scores, there was a differential impact with @entity227 subscales usually being affected more by reduced acuity than the more general QOL subscales.
