According to Smith, the intracapsular method would have been lost with Molroney, as he never wrote on the subject, if someone else had not come on the scene. Smith was led to try intracapsular extraction after he had observed in operations on nervous patients under cocaine anesthesia that occasionally, on completion of the incision, the patient, in screwing up the orbicularis muscle, shot out both the lens in its capsule and a quantity of vitreous. To his agreeable surprise, the results in these operations were generally good. In 1903, Smith published a report of 6500 intracapsular operations, and the era of the intracapsular extraction began.
