Cataract surgery in Bedele, Ethiopia. Cataracts are the main cause of blindness in Africa, and affect approximately half of the estimated seven million blind people on the continent, a number that is expected to increase with population growth by about 600,000 people per year.
Retinal detachment normally occurs at a prevalence of 1 in 1,000 (0.1%); however, people who have had cataract surgery are at an increased risk (0.5–0.6%) of developing rhegmatogenous retinal detachment (RRD)—the most common form of the condition. [78]

In America, cataract couching may have been performed in 1611, [30] while cataract extraction was most likely performed by 1776. [31] Cataract extraction by aspiration of lens material through a tube using suction was performed by Philadelphia-based surgeon Philip Syng Physick in 1815.
During CLEAR, the crystalline lens is extracted and an IOL replaces it in a process that is very similar to cataract surgery: both involve lens replacement, local anesthesia, last approximately 30 minutes, and require making a small incision in the eye for lens insertion. People recover from CLEAR surgery 1–7 days after the operation.
