Intraoperative OCT has great potential in corneal surgery
 Oliver Findl |
PRAGUE — "Live," continuous intraoperative optical coherence tomography is a powerful tool to guide treatment and enhance outcomes with penetrating and lamellar corneal surgery, according to one speaker here.
"Besides guiding treatment, it offers the opportunity to document our surgical cases and better understand surgical techniques," Oliver Findl, MD, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.
In his clinic, Dr. Findl has a Visante anterior segment OCT (Carl Zeiss Meditec) prototype connected with an OPMI VISU 200 operating microscope (Carl Zeiss Meditec) and uses it to assist in cataract, glaucoma and corneal surgery.
"In DSEK, when we strip the Descemet's, we can see if there are membrane's remnants. We can visualize the cut interface and measure the stromal bed thickness before doing the trephination. We can see the loading of the graft and how well it has been coiled up in the insertion device. We can see the graft entering the anterior chamber and then unfolding. With the bubble in place, we can see if there is fluid in the interface and if the graft is well centered," Dr. Findl said.
He has performed 15 Descemet's stripping endothelial keratoplasty procedures with this system, as well as a few penetrating keratoplasty procedures, and he is working on an efficient way of visualizing deep anterior lamellar keratoplasty.
"I don't perform [Descemet's membrane endothelial keratoplasty], but intraoperative OCT would greatly help avoiding upside-down graft placement," he said.
