Cataract surgery outcomes in the very elderly

The prevalence of very elderly patients (aged 85 years and older) with visually significant cataracts continues to rise in the United States. We conducted a focused review of literature using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to investigate the impact of very old age on cataract surgery outcomes. The studies suggest that very elderly patients, relative to their younger counterparts, had similar complication rates after adjusting for their higher rates of age-related ocular and systemic comorbidities. In addition, most very elderly patients gained improvement in visual acuity, enjoyed increased quality of life, and had survival rates that extend beyond 1 year after surgery. Although many of the studies were small and lacked statistical power to exclude clinically important differences in outcome, findings generally supported cataract surgery in the very elderly. Further studies are required to augment evidence-based surgical decision-making in elderly persons with ocular comorbidities and visually significant cataracts.
