Title: Computer-based Simulation of Strabismus Surgeries and Interactive Eye Motility Diagnosis

Speaker: Thomas Kaltofen

Affiliation: RISC Software

Abstract:  Every permanent or regularly occurring misalignment of the eyes is described as squinting (“Strabismus”). Thereby, the eyes are not parallel, but one eye diverges from the gaze direction of the other. About 4 to 6% of our population suffer from some form of strabismus. Squint is not just a cosmetic problem but often a severe visual impairment. The earlier squinting occurs in a child’s life and the later it is treated by an ophthalmologist, the more serious the visual impairment will get. Strabismus often has to be corrected through surgery of the outer eye muscles. Such surgeries have to be planned in detail and appropriate surgery procedures have to be chosen. In the past, it was only possible to carry out and perfect the process of a surgery directly on the patient. For complicated pathologies, even the experienced surgeon had to rely on documented empirical values, which often lead to multiple treatments until the result was satisfying.

This talk will provide an overview about the simulation system SEE++ ( for the prediction of clinical surgery results as well as for the illustration of pathological situations in the field of strabismus surgeries. SEE++ is based on a mathematical simulation model (biomechanical model) and features an interactive “virtual patient” for carrying out common clinical tests. The system simulates the behavior of the human eyes together with the extraocular muscles in a realistic way and therefore provides an experimental platform for the simulation of pathologies and the evaluation of possible surgical treatments.

Short Bio:  Thomas Kaltofen has studied Software Engineering at the University of Applied Sciences Upper Austria, Campus Hagenberg (FH Hagenberg), where he already started working on SEE++. Later, the work was continued in the Research Unit Medical Informatics at the Upper Austrian Research GmbH and since 2008, he is working at RISC Software GmbH as Project Manager and Software Developer.
