Keratome and scissors.

چکیده
THE problem of the perfect cataract section and how it should be made is prominent in the minds of ophthalmic surgeons. We are all aware that the success of a lens extraction is substantially dependent upon the accuracy of the section, and there are few of us who cannot recall tragedies or near-tragedies resulting from the improper opening of the eye. With this in mind, and in spite of average proficiency with a Graefe knife, I was prompted to try making the section with keratome and scissors, and having done so in some fifty cases, am convinced that it is the better method. I am well aware that the qudstion of knife or keratome is an old one, and that most established surgeons have by now made up their minds in the matter, but my excuse for this note is that, having had better and more consistent results with the keratome, I felt that others might perhaps be interested in the several reasons which caused me to change my technique.

Keratome or knife incision for cataract; assessment of 180 cases.
DAVIEL (1753) described the first satisfactory method of cataract extraction before the Academie Royale de Chirurgie in 1752. He opened the eye with an instrument similar to the modern keratome and enlarged the incision with scissors. This method gradually displaced the ancient practice of couching until von Graefe described his cataract knife for making the incision in 1865. Von Graefe's catar...

There are many techniques of cataract extraction and many types of cataract knives have been devised to facilitate an ideal section. Ultrasharp diamond knives were introduced by Durham and Luntz (I968). Sharpness is essential whether the von Graefe knife, the keratome, or corneal scissors are used, and for this reason disposable cataract knives, keratomes, and Bard Parker blades are widely used...

PURPOSE To compare the consistency of incision architecture utilizing a traditional diamond keratome and a newly designed diamond keratome. METHODS We used a traditional diamond keratome and newly designed diamond keratome to create clear corneal incisions in human cadaveric donor eyes. Three surgeons with varying levels of experience made 30 incisions with each keratome; and the wound archit...

indifferent incisions, and in two cases where the iris rose above the knife, the complete iridectomies followed the normal course during convalescence. In assessing the relative merits of the two methods of extraction one must consider two factors: (a) the von Graefe method is simple and quick, and has withstood the test of time and usage in many thousands of cases: its drawbacks are known and ...
