The author thanks Drs Grzybowski and Ascaso for bringing to his attention the pioneering work of Dr José Morón, who performed early studies on the use of light photocoagulation in rabbit and human eyes beginning in 1945. Because these studies were conducted within the context of a doctoral dissertation, which was not published in a peer-reviewed journal or able to be accessed through a search of PubMed as of August 2013, I was unaware of his work until provided with this correspondence. However, in a search of the literature subsequent to receiving this notification, I was able to identify one article published in German by Remky and Amalric in 1990 that confirmed Jose Morón’s work in 1946, prior to the first publications by Gerd Meyer-Schwickerath in 1949. In their history of photosurgery of the eye, Drs Remky and Amalric also allude to the use of photocoagulation on a human eye in 1817 by Hieronymous Hess of Basel for therapeutic coagulation in 1835. Reaching further back into history, it has been suggested that Plato either used or was aware of photocoagulation by the sun to treat the eye, in a translation by Benjamin Jowet in 2006. It would seem, as stated in my Jackson Lecture: “Finally, in keeping with the adage that, while failure is an orphan, success has many fathers, the history of the laser, which has had so many positive disruptive impacts in every facet of modern-day life, continues to be written and rewritten.” The author again thanks Drs Grzybowski and Ascaso for their thoughtful and well-documented information indicating that attempts had been made to perform photocoagulation in humans in the modern era even prior to Meyer-Schwickerath’s first documented approach in 1949.
