Cataract surgery: What to expect before, during and after
Cataract surgery is one of the oldest procedures still being performed today. Ancient Egyptians used a surgical technique known as “couching,” in which a sharp needle was used to slide the cloudy lens out of the field of vision and into the vitreous cavity in the back of the eye. Later, the Romans used a method called “needling” to slice up the cataract into pieces small enough to be reabsorbed.
