Purpose:
To examine changes in visual, psychological, and functional disability in older people waiting for cataract extraction and 6 months after surgery.
Setting:
Community-based study in Northeast England.
Methods:
Participants were 92 patients (mean age 78.1 years +/- 6.5 [SD], 79% female) with age-related cataract. Questionnaires were administered at time of listing for cataract extraction, 2 weeks preoperatively, and 2 and 6 months after surgery to assess visual symptoms and function, anxiety and depression, perceived health status, cognition, and activities of daily living.
Results:
Mean waiting time was 265 +/- 64.4 days. Forty-six patients had first-eye surgery, 39 had second-eye surgery, and 7 had sequential-eye surgery (both eyes operated on during follow-up). During the waiting period, there were no significant changes in visual symptoms, cognition, or functional abilities. However, perceived health status, anxiety, and depression improved significantly during this time. For first- and second-eye patients, surgery resulted in significant improvements in all questionnaire scores, except activities of daily living.
Conclusions:
Despite waiting 9 months for cataract surgery, patients did not decline in visual symptoms, social functioning, or cognition. In first- and second-eye patients, successful cataract extraction resulted in significant gains in visual function, cognition, and emotional and general well-being. The benefits of cataract surgery in older people extended beyond simple measures of visual acuity.
