The purpose of this study was to examine the correlation between those adults aged 50 years and older who have been diagnosed with cataract(s) and those who then choose to have cataract extraction via surgical intervention. The main purpose of this project is to show that individuals older than 50 years old diagnosed with cataracts are more likely to have cataract extraction than to not have cataract extraction. In order to see if this conclusion is valid, the data from the NHIS 2008 was used in the following manner: (1) An independent t-test was conducted to see the association between age and those having cataract extraction surgery; (2) The use of a χ 2 test to evaluate if there was a correlation between gender and those having the cataract extraction procedure; and (3) Again the use of a χ2 test to evaluate the association of visiting an eye care professional and being diagnosed with cataracts. The results showed there was an observed significant relationship between older age and those having cataract surgery; therefore, Hypothesis I was supported. Hypothesis 2 was not supported: men were not more likely to have cataract extraction surgery when compared to their female peers. Lastly, Hypothesis 3 was also supported as there is an association between a visit to an eye care professional in the last 12 months and being diagnosed with cataracts.
