Cataract
Sources:
Cataracts are a significant cause of vision loss worldwide, but they are quite treatable with surgery. According to , cataract surgery is an efficient process that usually takes about 4 to 12 minutes. The procedure involves removing the cloudy lens and replacing it with a clear plastic lens. This method is highly successful—effective in 99% of cases—and even advanced lenses can now adjust focus for both distant and near vision 1.
However, the global challenge remains access to care, as there are not enough cataract surgeons and resources in many parts of the world, particularly in developing countries. This issue makes cataracts the second leading cause of vision loss globally due to insufficient treatment access 1. Meanwhile, cataracts are part of the normal aging process, and as people live longer, more will require surgery to address them 2.
