what constitutes "backbench Preparation" of corneal tissue.

Donna Posted Tue 11th of December, 2012 18:56:29 PM

When our Doctors do a DSEK I'm not sure if they do a backbench prep of the corneal tissue because I can never find a definition of what is involved. Please advise

Hi,

Here is what the physician performs in order to qualify for 65757 :

The surgeon prepares the endothelial graft in the operating room and prepares the artificial anterior chamber (AAC) on which the donor cornea will be mounted. He secures the donor cornea to the AAC and measures the pressure in the system. He removes the corneal epithelium under the microscope and makes a reference mark to the donor cornea. After hydrating the material and setting the microkeratome to an appropriate depth, the surgeon measures central corneal thickness (pachymetry). He inspects the microkeratome and cuts the corneal cap from the donor material. He retrieves the cap from the microkeratome and realigns it on the donor bed using the previously placed marker. Finally, the surgeon removes the donor material from the AAC.
