The value of simultaneous OCT examinations during surgery using the optical pathway of the microscope has been already shown by our group using a prototype , consisting of a combination of a VISU 200 Microscope and a Cirrus OCT (Zeiss Meditec, Oberkochen) . The useability of a continuous integrated OCT during posterior segment surgery (Lumera 700 and Rescan 700) should be tested.
RESCAN 700 OCT integrated into a Lumera 700 Microscope was tested
This new continuous OCT was tested in 50 patients undergoing combined cataract surgery and parsplana vitrectomy . Indications for surgery were preretinal membranes, Vitreomacular trachtion, macular holes , macular edem and retinal detachments. An informed consent was signed in every case. The system was tested for useability , video quality, possible time loss, and individual gain of information during surgery supporting surgical decisions.
OCT Scan quality visible also in the surgeons ocular was excellent in all cases. The use of the simultaneous OCT was easy and quickly to learn and did not hinder the surgeons view. Surgical time was not delayed using the system The simultaneous use of the continuous OCT was helpful in finding the correct location to start membrane peeling, , observing surgical trauma on retinal tissue during peeling, , juging about macular hole size changes during surgery and detecting residual membranes after the first peeling, .
The new generation of continuous fully microscope integrated OCT: RESACN 700 does improve surgical decissions during surgery without time loss.
