Pre-academic training:

Lemij went to various primary schools in several countries, since his parents worked with an international oil company. His secondary school was the Rijnlands Lyceum in Wassenaar, The Netherlands.


Academic and medical training:

1978 - 1985                 Medical school at the State University of Leiden, The Netherlands. Lemij graduated cum laude.

1985 - 1987                 Military service in the Royal Dutch Navy, largely as a resident in Psychiatry at the Marine Hospitaal (Navy Hospital), Overveen, The Netherlands.

1987 - 1989                 PhD-student at the Erasmus University, Rotterdam, The Netherlands. He worked at the Department of Physiology I, super­vised by Prof. H. Collewijn. Lemij's research was into the con­jugacy of saccadic eye movements. More specifically, Lemij ex­amined adap­tation of the human saccadic oculomotor system to anisometropic spectacles requir­ing nonconjugate saccades. Lemij graduated cum laude. His thesis was awarded with the Hamburger prize, as well as the Binkhorst prize.

1989 - 1993                 Residency in ophthalmology at the Rotterdam Eye Hospital, Rot­terdam, The Netherlands. The head of the residency program­me was G.S. Baarsma, MD. Dur­ing the residency, Lemij be­came increas­ing­ly inter­ested in glaucoma.

1993                            Lemij spent 3 months visiting various glaucoma specialists in the United Kingdom, the United States of America and The Netherlands.

1993 - date                  Lemij joined the faculty of The Rotterdam Eye Hospital as a glaucoma specialist and as an anterior segment surgeon. He was the Scientific Director of the Rotterdam Eye Hospital till 2009. He served on the Rotterdam Eye Hospital’s Science Committee. This committee was renamed into the Institutional Review Board after a merger with the hospital’s Medical Ethics Committee in January 2004. Lemij’s own research activities initially focussed on the oculomotor system, but more recently on glaucoma. In glaucoma, most early research was into scanning laser polarimetry, a technique that determines in vivo the thickness of the retinal nerve fiber layer, a thin tissue that is affected in glaucoma. Lately, several other imaging technologies used in glaucoma have been added to his research activities. He has also developed an interest in shared glaucoma care, i.e., delegating clinical tasks to other eye care professionals, optometrists and technicians, both within and outside the hospital setting. In 2004, he extended his research activities to genetic epidemiology of glaucoma. In addi­tion, Lemij regularly ­gives courses in glaucoma and perimetry to oph­thal­mologists, residents and ophthal­mic technicians throughout The Netherlands and abroad. The clinical use of structural imaging (stereoscopic fundus photography, scanning laser polarimetry and optical coherence tomography) are other topics of his regular courses.  He established and chaired the Dutch Humphrey Perimeter Users Society; this society changed its name in 2008 to the Stichting Anatomy and Function of the Eye (SAFE), in order to also pay attention to imaging technologies in the management of glaucoma. Lemij is the president of SAFE. He also chairs the Dutch Glaucoma Group (a group of glaucoma specialists and ophthalmologists with a special interest in glaucoma in the Netherlands). He established the Imaging Morphometry Association for Glaucoma in Europe (IMAGE) in 2002. He helped establish the Glaucoma Genetic Epidemiology Network in Europe (GlaucoGENE) in 2004. From 2006 till 2010, he was a visiting Professor at the Catholic University of Leuven, Belgium.

1998 – 2004                Lemij chaired the Medical Ethics Committee of The Rotterdam Eye Hospital. As mentioned earlier, this committee changed into the Institutional Review Board in January 2004.

2009                            Lemij became vice-chair and secretary of the medical faculty of the Rotterdam Eye Hospital. He also joined the advisory board of Health Base, the publisher of “Commentaren Medicatiebewaking”, a reference manual for Dutch pharmacists.

2010                            Lemij became a member of the Glaucoma Experts Committee of the European Institute of Vision (EVI).

2011                            Lemij joined the Advisory Board of the review journal Framingham on ophthalmology.

2011                            Lemij joined the European Advisory Board of Laboratoires Théa.

2013 through 2019      Lemij was elected as chair of the medical faculty of the Rotterdam Eye Hospital. The medical faculty of the Rotterdam Eye Hospital consists of 36 ophthalmologists, working in 4 locations: the Rotterdam Eye Hospital, as well as in 3 other franchise locations, within general hospitals in the Rotterdam area: the Sint Franciscus Gasthuis, the Havenziekenhuis and the IJsselland Ziekenhuis. The number of collaborating hospitals is expected to grow.

2015 through 2019      Lemij served as a Medical Director of the Rotterdam Eye Hospital. In addition, he continued seeing and operating on glaucoma and cataract patients.
