Iraqi Ammar bin Ali Al Mawsili [1] who attempted the earliest extraction of cataracts using suction. He invented a hollow metallic syringe hypodermic needle, which he applied through the sclerotic and successfully extracted the cataracts through suction.[citation needed] He wrote the following on his invention of the hypodermic needle and how he discovered the technique of cataract extraction while experimenting with it on a patient:
"Then I constructed the hollow needle, but I did not operate with it on anybody at all, before I came to Tiberias. There came a man for an operation who told me: Do as you like with me, only I cannot lie on my back. Then I operated on him with the hollow needle and extracted the cataract; and he saw immediately and did not need to lie, but slept as he liked. Only I bandaged his eye for seven days. With this needle nobody preceded me. I have done many operations with it in Egypt."[2]
