[Evaluation of instrument improvements in oculomotor muscle surgery]

Five improvements of surgical instruments for strabismus-surgery are introduced; these are a small muscle-hook, a broad, flat muscle-hook, two variants of a retractor and one instrument for the resection or tucking of a rectus-muscle. All instruments have proved to be less traumatic and seem much safer than others even in less experienced hands. Most of them have been used over a period of more than 10 years in a specialized department.
