On leaving Macartney, Jacob joined with Graves and others in founding the
Park Street School of Medicine. In 1826 he was elected Professor of Anatomy and Physiology at Royal College of Surgeons in Ireland (RCSI), and held the chair until 1869. He was elected President of RCSI in 1837 and 1864. Jacob founded an Ophthalmic Hospital in Pitt (now Balfe) Street in 1829 and in 1832, in conjunction with Charles Benson and others, he founded the City of Dublin Hospital, Baggot Street and later practiced there after the opening of a dedicated eye ward. His younger rival,
Sir William Wilde, subsequently founded the competing St. Mark's Ophthalmic Hospital in Lincoln Place (beside Trinity College) in 1844.
In 1839, with Dr. Henry Maunsell, he started the
Dublin Medical Press, a weekly journal of medical science, and edited forty-two volumes (1839 to 1859), in order “to diffuse useful knowledge… to instil honourable principles, and foster kind feelings in the breast of the student” among other desirable aims.
He also contributed to the
Dublin Journal of Medical Science. He took an active part in founding the Royal Medical Benevolent Fund Society of Ireland and the
Irish Medical Association.
At the age of seventy-five he retired from the active pursuit of his profession. His fame rests on his anatomical and ophthalmological discoveries.
In December 1860 a medal bearing Jacob's likeness was struck and presented to him, and his portrait, bust, and library were later placed in the Royal College of Surgeons in Ireland. He died at Newbarnes,
