Abstract

The most common complications of the strabismus surgery are related to the muscle sagging, lost muscle in suturing procedure and needle trauma endophthalmitis, retinal detachment, scleral necrosis result from scleral perforation. The authors developed the muscle clamping system with absorbable jaw clip, and operated on 8 rabbits using the clips. The right superior rectus was recessed by conventional recession and the other superior rectus was recessed with an absorbable jaw clip. We examined the conjunctival injection, muscle adhesion power (bond strengths) and light microscopic findings at postoperative I week, 2, 4, and 8 weeks. Conjunctival injection was diminished with time and bond strengths ranged 400-500gm in right eye and 380-600gm in the left eye. Microscopically there were some inflammatory cells and less foreign body reactions in jaw clipped eye. According to these results, muscle clamping method employing the newly invented clip could be an innovatory surgery which may overcome many difficulties of the surgery and avoid any possibility of misleading practice along with convenience.
