David Allen is a Consultant Ophthalmologist at Sunderland Eye Infirmary, England and was responsible for developing their high volume Cataract Treatment Centre which was recently doubled in size. This is now regarded as one of the most efficient cataract units in the UK. His main interest is in cataract surgery, and he was president of UKISCRS 2002-2004.

He has published 6 chapters in books relating to cataract surgery and phaco-emulsification equipment and techniques. He has published around 40 articles on cataract surgery outcomes, techniques and phaco equipment. One of his passions is teaching about phaco techniques from the standpoint of understanding exactly what the surgeon requires, and how this can be provided by the phaco machine. From 1996 he has organised teaching courses at the Annual meetings of both the European and the American Societies of Cataract & Refractive Surgery dealing with both the basic principles of phaco, as well as early recognition of situations potentially leading to complications if not recognised.
