What Are Cataracts?

1. Epidemiology/Statistics
It is estimated that 51% (20 million) of world blindness is due to age-related cataracts. Worldwide, it causes moderate to severe disability, especially in countries with low and middle income. This is thought to be due to the inadequacy of surgical services. Even in countries where surgical services are available, disability due to cataracts may still be prevalent as there are barriers such as cost, long waits, and transportation issues. In the United States, it has been reported that this condition affects 42% of those between the ages of 52 to 64, 60% between 65 and 74 years, and 91% between 75 to 85 years old. Annually, the estimated direct medical costs are estimated to be $6.8 billion.
