Cataract

Cataracts, a progressive opacification of the crystalline lens, are an eye disease affecting around 50% of the population over the age of 60.

Generally characterized by a loss of transparency of the crystalline lens, resulting in reduced quality of vision, cataracts progress slowly, often in stages. It can be hereditary or traumatic, total or partial. However, the most common cataract is age-related. As such, it is the leading cause of blindness worldwide, according to the WHO (World Health Organization). Highly prevalent in developing countries, 40% of blindness is due to senile cataract and aging of the eye, and more specifically of the crystalline lens.

Diagnosed centuries ago, the best-known example is that of painter Claude Monnet. In fact, during the last years of his life, he suffered from cataracts, but did not give up painting. Continuing to draw and paint works he had already created, he was able to show the evolution of his illness.

The disease affects both eyes, causing discomfort in the presence of light and reduced visual comfort, and can be cured by surgery. Every year, almost 600,000 operations are carried out in France. this means that 20% of the population aged 70 and over are forced to undergo this operation.
