Abstract |
We report the results of the Impact of Cataracts on Mobility (ICOM) project that was designed to address the question, for those older drivers who have cataract, what is the impact of cataract surgery on crash rate in the 4 years following surgery compared with those who have cataract who do not elect surgery? Strengths of this study design are the use of a comparison group of patients with cataract who do not undergo surgery followed prospectively over the same time period and the statistical adjustment for potential differences in the surgery and no surgery groups at baseline that could serve as confounders for the hypothesized effect. Using a randomized design would have been unethical since cataract surgery with intraocular lens implantation is an accepted and proven standard of care. |
