Racial differences in the prevalence of intraocular lens implants in the United States.
We generated population-based estimates of the prevalence of intraocular lens implants by using the 1988 Medical Device Implant Supplement to the National Health Interview Survey. This national survey of a probability sample of the civilian noninstitutionalized United States population comprised 47,485 households and 122,310 persons. To produce national projections, we used survey respondent-reported data based on 1,941 reported intraocular lenses in 1,337 persons. Projected to the United States population, an estimated 2.6 million people had a total of 3.8 million lens implants. The predominant reason for the implant was cataract. The intraocular lens replacement rate was 0.9%. The use of intraocular lens implants was statistically significantly different from the general population in persons with the following socioeconomic characteristics: age (65 years or older), race (white), gender (female), annual family income (less than $20,000, although more commonly at or above the poverty threshold), and education (less than high school). The prevalence rates per 1,000 persons according to age were as follows: 0.3 for persons 44 years old or younger, 9.9 for persons 45 to 64 years old, 33.3 for persons aged 65 to 69 years, 63.5 for persons aged 70 to 74 years, and 113.5 for persons 75 years old or older.(ABSTRACT TRUNCATED AT 250 WORDS)
