Summary
Cataract surgery incidence is 7.4% annually, with significant vision improvement post-operation. Older adults and those with Medicare had higher rates, while Black individuals had lower rates.
Area of Science:
- Ophthalmology
- Gerontology
- Public Health
Background:
- Cataract surgery is a common procedure for vision restoration in older adults.
- Understanding the incidence and factors influencing cataract surgery rates is crucial for healthcare planning.
Purpose of the Study:
- To determine the cumulative probability of cataract surgery.
- To identify demographic and socioeconomic factors associated with undergoing cataract surgery.
Main Methods:
- Longitudinal analysis of the Asset and Health Dynamics Among the Oldest Old survey (N=8363).
- Multivariate analysis to identify factors affecting cataract surgery rates between 1998 and 2002.
Main Results:
- Annual cataract surgery incidence was 7.4%.
- Prevalence of bilateral pseudophakia increased significantly from 10.5% to 22.3%.
- Surgery was associated with improved self-reported vision, higher rates in older adults (≥65 years) and Medicare beneficiaries, and lower rates in Black individuals.
Conclusions:
- Cataract surgery incidence is consistent with prior research.
- Individuals with poor pre-operative vision experienced significant visual improvement after surgery.
- Disparities in access to cataract surgery exist based on race and insurance coverage.
