The first cataract surgery was performed by the ancient Indian physician Sushruta, way back in 6th century BCE. To remove the cataract from the eyes, he pushed the lens and used a curved needle to remove it, which were then kept immersed in warm butter for a few days till they were healed completely. Many people from various other countries came to India to seek treatment from Sushruta. His surgical works were later translated to Arabic language and got transported to the European countries.
