Abstract Details

Purpose:

To assess the feasibility of a novel continuous intra-operative spectral domain optical coherence tomography (OCT) device integrated into the operating microscope for anterior segment surgery

Setting:

Vienna Institute for Research in Ocular Surgery (VIROS), Hanusch Hospital, Vienna

Methods:

Assessment of an intra-operative OCT that is integrated into the operating microscope (Rescan 700, Carl Zeiss Meditec AG, Germany) for use in lamellar corneal surgery (DSAEK, DALK) as well as for assessing incision architecture during cataract surgery. In an observational case series, patients undergoing lamellar corneal surgery as well as cataract surgery were included.

Results:

The continuous intra-operative spectral domain OCT was clinically applicable in all operations performed in this series. Due to the fact that the device allows the surgeon to directly view the OCT scan through the eyepiece and control the OCT using the foot pedal, no assistance is needed in the operating theatre during surgery. For DSAEK, it was simple to assess whether fluid was in the interface between transplant and recipient cornea. For DALK, this technology may be helpful to guide the surgeon to find the right depth of the needle/cannula before creating a “big bubble”. For cataract surgery, detection of small changes of the incision architecture was possible. Furthermore, the intra-operative OCT was able to detect lens fragments hitting the corneal endothelium during phacoemulsification.

Conclusions:

For corneal and cataract surgery, the continuous spectral domain OCT integrated into the operating microscope appears to be a valuable device to guide and document surgery.
