Eventually the Blatt family was released from jail, though Blatt was refused work by most medical institutions; he was hired as a practicing ophthalmologist by a small policlinic on the outskirts of Bucharest. A group of European and American ophthalmologists headed by Professor Francesco Bietti of Italy then met at an international congress to discuss how to obtain the release of Blatt and his family from Romania. Ultimately his wife's sister in Toronto, Canada, paid the Romanian Government for their release, which happened in 1964. The French Government granted the Blatt family a visa for an unlimited period, and they moved to Paris in August 1964. In October 1964, he was appointed Guest Professor of Ophthalmology, and given a research laboratory, at the Goethe University Frankfurt in West Germany. After a short period of teaching and beginning some research projects, Blatt died aged 74 after a short illness on April 10, 1965, at the university hospital in Frankfurt. Marta Blatt continued living in Frankfurt. She died seven years later, aged 67. Blatt published 373 papers in several foreign ophthalmology journals, mostly based on his research. A number of these were republished as "Cercetări şi studii in oftalmologie".
