Cataract is a disease affecting the crystalline lens of the eye, which gradually becomes opaque. In the beginning, eyesight is seriously affected. After some time, the eye no longer functions at all, and the victim finally loses his eyesight. This disease, with its dramatic consequences, striking nursing infants as well as elderly persons, can nevertheless be easily treated: it "suffices" to remove the crystalline lens and replace it with external lenses or with implants.
In Morocco, due to the very large number of sand particles suspended in the air, it is estimated that about 700 000 persons develop blindness due to cataract at some time in their lives. In the month of June 2007, Adefram (Association pour le développement des échanges franco-marocains) conducted its seventh campaign of operations on cataract.
