The separation of thin conjunctival tissue in the preparation of a conjunctivoplastic covering of the cornea can be greatly facilitated by the use of blunt dissection with an iris spatula.
The technique of conjunctival-flap surgery as advocated by Gundersen in his article, "Conjunctival Flaps in the Treatment of Corneal Disease With Reference to a New Technique of Application," published in the November 1958 issue of the Archives (60: 880 [Nov] 1958), is precisely followed. The only exception to this method is that pertaining to the separation of conjunctiva from the underlying tissues. Gundersen advises meticulous sharp dissection of the two tissue layers utilizing fine pointed scissors and forceps. This is a rather delicate and time-consuming process which carries a hazard of perforation of the paper-thin conjunctiva.
This stage of the procedure can be facilitated by establishing a
