Lowering accident risks for older drivers continues to be a major challenge for Indiana transportation agencies as the number of such motorists in the state increases. A new study finds that better vision through cataract surgery can help reduce those risks.
The Canadian study found that accident rates for more than half a million drivers actually dropped after the drivers underwent a required cataract surgery. The decline was a fairly modest one of about 9%, but it does establish that improved vision as the result of a cataract surgery can help decrease driving risks. Cataract surgery also seemed to substantially reduce accident risks among older drivers. Accident rates dropped by as much as 14%, among drivers above the age of 70. Overall, the researchers estimate that one accident can be prevented for every 5000 cataract surgeries that are performed.
