Objective 28-7


Reduce visual impairment due to cataract

Cataract is a leading cause of vision loss. This disorder sometimes occurs in children, but most frequently occurs in adults age 50 and older. The only treatment for cataract is surgical removal of the lens, followed by implantation of an artifical lens at the time of surgery or the subsequent use of corrective lenses. Approximately 1.35 million cataract operations are performed annually at an estimated cost of $3.5 billion.

Data Source

Baseline: 118.8 per 1,000 persons aged 65 years and older reported they had trouble seeing and cataracts in 2002 (age adjusted to the year 2000 standard population).

Target: 91.4 per 1,000 persons 65 years and over.

Target setting method: Better than the best.

Data source: National Health Interview Survey (NHIS), National Center for Health Statistics (NCHS), Centers for Disease Control and Prevention (CDC).

Operational definition: This is a valuable tool that allows individuals to set measurable Healthy Vision objectives for their own communities.

Operational definition for objective: 28-7
28-7. Reduce visual impairment due to cataract.
National Data Source National Health Interview Survey (NHIS), CDC, NCHS.
State Data Source Not identified.
Healthy People 2000 Objective Not applicable.
Measure Rate per 1,000 population (age adjusted - see Comments).
Baseline 118.8 (2002).
Numerator Number of adults aged 65 years and older who report they have trouble seeing and that they have ever been told they had cataracts.
Denominator Number of adults aged 65 years and older.
Population Targeted U.S. civilian, noninstitutionalized population.
Questions Used To Obtain the National Data From the 2002 National Health Interview Survey:

> Do you have trouble seeing, even when wearing glasses or contact lenses?

> Have you ever been told by a doctor or other health professional that you had cataracts?
Expected Periodicity Periodic.
Comments Adults who answer "yes" to the abovequestions meet the criteria for the objective as closely as possible using self-report.

Data are age adjusted to the 2000 standard population using the age groups 65-74 and 75 years and older. Age-adjusted rates are weighted sums of age-specific rates. For a discussion on age adjustment, see Part A, section 5.

For some measures, data do not meet the criteria for statistical reliability, data quality, or confidentiality and have been suppressed. Information on suppression of data for the major Healthy People 2010 data systems has been published in a Healthy People Statistical Note report (Klein, R.; Proctor, S.; Boudreault, M.; Turczyn, K. Healthy People 2010 Statistical Notes No. 24. 2002).
