It has been said that phaco-emulsification is dying out but the opposite is true. In 1971 there were only 5 machines whereas in 1977 there were 644. Beginning and advanced courses are offerred at several institutions on a regular basis. In 1971 only 47 surgeons were trained and by 1977, 2634 surgeons in the U.S. and 183 abroad. The equipment is used in 34 clinics in Europe. In 1971 only 230 procedures had been performed but by 1977 over 120,000 procedures had been done. The new model 8000 delivered 35% more power than the first model and 15% more power than the 7007 model.
