Objective: In Cüppers-operation or “Faden-Operation” shortening of the lever arm of eye rotation is achieved by fixation of the medial rectus muscle 12-15mm behind the insertion. In Y-splitting-surgery of the medial rectus muscle the eye muscle is split in to equal parts and refixed on the sclera with free arc of contact in Y-shape. The technique which is termed Y-splitting is demonstrated in a video presentation.
Methods: Before the operation factors like axial length of the globe and corneal diameter have to be measured. In Y-splitting surgery the eye muscle is split in two parts with a splitting length of 15-17mm, followed by refixation on the sclera with free arc of contact in Y-shape. The position of the refixed muscle parts have to be calculated according the pre-operative measured angle.
Results: This operative procedure reduces the strabismus, eliminates or weakens the nystagmus in primary position and can improve binocular vision and visual acuity. Side effects seem to be less than in Cüppers procedure.
Conclusions: Y-splitting surgery of the medial rectus muscle provides an alternative to Cüppers “Faden-Operation”. In Y-splitting surgery motility as well as convergence is almost not impaired incomitantly. The risk of perforating injury of the sclera in comparison to the “Faden-procedure” is reduced and therefore suitable also in myopic eyes and in only one functional eye situations.
