Dr Steiner has over 35 years experience in eye surgery with a particular interest in cataract, glaucoma and laser refractive surgery.

After graduating in Medicine from Sydney University in 1970, he was admitted as a Fellow of the College in 1974 and two years later was appointed to the position of Honorary Secretary of the College. He was appointed an Honorary Ophthalmic Surgeon to Bankstown and Lewisham Hospitals and pioneered intraocular lens implantation for cataract in both of these institutions where he served from 1975-1984.

Michael has been performing laser vision correction since it was first introduced to Australia in 1991. He is a Foundation Member of the Australasian Society of Cataract and Refractive Surgery.

Dr Steiner is a Fellow of the Royal College of Ophthalmologists of the U.K. and a member of the Oxford Ophthalmological Congress. He has been involved in the organisation of many scientific congresses for the Royal Australian and New Zealand College of Ophthalmologists and has been the Chairman of annual Scientific Congresses at both the State and National level.

He was a RANZCO Councillor for many years and served as President of the College in 1999-2000. He was President of AMA NSW 2010-2012 and a Councillor of the Federal AMA 2004-2012. He was awarded the Australian Centenary Medal in 2003 and was elected a Fellow of the AMA in 2006.

Dr Steiner received RANZCO's College Medal in November 2014 for eminent service by a Fellow that is exalted or remarkable in degree in duties of great responsibility.

Identifying the need for ophthalmology to have a medico-political representative body to protect scope of practice and prevent the erosion of the value of cataract surgery, Dr Steiner instigated the formation of the Australian Society of Ophthalmologists.

Dr Steiner was appointed to the position of President of the Australian Society of Ophthalmologists in November 2014.
