Kraft has research interests in problems of eye muscle balance (strabismus), binocular vision, and amblyopia ("lazy eyes") in both children and adults. He has published 111 papers in peer-reviewed journals and 46 book chapters on a wide range of topics in these areas. These subjects include reasons why children develop eye muscle problems and how their eyes learn to work together, variations in the anatomy of the eye muscles and the eye sockets and how they affect the eye muscle balance, and how to diagnose various eye muscle conditions. He has also pioneered surgical approaches to treat unusual and difficult strabismus problems. Kraft has collaborated on numerous projects including recent work on the success of adjustable suture eye muscle surgery, prevention of infections after eye muscle surgery, and also the demographics of strabismus care in Ontario.
