Strabismus.—Division of the. Rectus by means of Lane's Knife made
by Savigny.—Every improvement in surgery is interesting, and we
eagerly seized the opportunity afforded us by the kindness of Mr. Gay
of seeing this instrument used. It is a small curved bistoury, with a
partially blunt point. The patient was a little girl. Placed under the
influence of chloroform, Mr. Gay, having fixed the eye, introduced the
knife by the under side of the rectus, and, holding it flat, passed it ver-
tically on. Owing to its peculiar construction, it went close under the
tendon, the point becoming prominent on the other side. On this the
operator placed his finger, turning the knife up, when it cut its way out.
A second touch of the knife was required, whereupon the globe of the
eye instantly resumed its normal position. As nothing can be more
simple than this instrument, we sincerely wish to see ittriedstill further.
Its advantages, we are given to understand, are, that from its construc-
tion, its point will pass through all the textures external to the sclerotic,
but that no force can make it penetrate this membrane.—London Med.
