Excerpt from The "Hohlschnitt" Of Von Jaeger in the Extraction of Cataract, Cilio-Retinal or Aberrant Vessels, Sarcoma of the Eyelid, Simulating a Meibomian CystThe construction of the Graefe knife permits of puncture and counter-puncture without any loss of aqueous, but, with the first movement towards the division of the bridge of tissue which remains to be severed, begins the draining away of this ¿uid, the pressing forward of the iris, and the diminution of the tension of the eyeball. A skilful hand can generally keep the knife-edge free Of the iris, and can mitigate the violence done to the eye as the sawing section drags upon the ¿accid cornea, stretched between the fixation forceps below and the knife above. The zonula will stand a good deal, and only occasionally ruptures, and thus early in the Operation permits loss of vitreous. But these are variations in degree, not in kind, and the most skilful Operator will not always escape awkward complications. Could he complete his incision with out loss of aqueous, not only would it be impossible for the iris to engage the properly placed knife-edge, but the tension of the eyeball, maintained by the retention of the humor and increased by the addition of the knife-blade to its normal con tents, would permit a smoother, cleaner section, which, like that of a lance knife, may always be expected to heal more kindly than a rougher one. Further, could the fixation of the globe be made largely or exclusively at the points of puncture and counter-puncture, close to where the incision is being completed, the drag upon the eye would be reduced to that incidental to the friction of: the knife in the wound.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
