By modelling the soft tissue biomechanics and the suspension of the human eye Dr. Sander Schutte, who recently defended his thesis on this topic at the MMME faculty, believes surgery to correct strabismus, or cross eyes, can be improved.
Strabismus is usually corrected surgically by relocating the insertion of one eye muscle on the eye a few millimetres backwards. “It is a very straightforward operation requiring no more than a ruler, a pair of scissors and thread and a needle. And the procedure has hardly changed since it was first devised in the nineteenth century”, says Schutte. Unfortunately about twenty percent of all patients need a reoperation because their strabismus was over or under corrected. One cause of this error is the fact that the anatomy and physiological properties of the eye, the muscles and the orbital fat vary greatly between patients.
