Synopsis

Excerpt from The Ophthalmic Record, Vol. 3: October, 1893

A little reasoning ought, it seems, to convince any one of the fallacy of such reasoning. In the first place, the globe of the eye by reason of the tensile strength, inelasticity and resiliency of the outer covering, sclera and cornea, tends to preserve its proper curvature and shape unless divided to more than half its circumference. One can easily demonstrate the principle with a hollow rubber ball, by making a clean incision in it with a sharp knife. If the ball is not subjected to pressure the line-of the incision is closed so effectually the place can hardly be found; but the slightest pressure on any portion of the ball will cause the incision to gape. So it is with the eye. Every one who has made many corneal sections has certainly been impressed with this fact. A nice clean section in the cornea, if no pressure on the globe by speum or other instrument is permitted, will coapt so nicely that the place can scarcely be discovered; but the slightest touch on the globe will cause the wound to open.

The ideal condition for primary union in such a wound is to leave it in just the condition we see it when quiescent. How is this best accomplished? We know that the lids are perfectly adjusted to the front surface of the eyes, and are intended for their natural protectors.
