According to 3-year results of the DISCOVER study, microscope-integrated intraoperative OCT during ophthalmic surgery is feasible and useful as it relates to surgical decision-making.
The large-scale study enrolled 837 eyes, of which 244 eyes were enrolled in the anterior segment arm and 593 eyes were enrolled in the posterior segment arm.
In 216 patients in the anterior segment arm, intraoperative OCT provided valuable feedback, most frequently when evaluating the graft-host apposition and when assessing the extent of interface fluid in Descemet’s stripping automated endothelial keratoplasty and Descemet’s membrane endothelial keratoplasty. In 106 patients, the information resulted in changes to surgical decision-making.
In the posterior segment arm, intraoperative OCT was identified as adding valuable surgical information in 352 patients. Added value was related to the procedure, surgical anatomic features or both. In 173 patients, the added value directly affected the surgical procedure.
“The DISCOVER study has demonstrated both the feasibility and usefulness of [intraoperative] OCT as it relates to surgical decision-making in both anterior and posterior segment surgery,” the study authors wrote. – by Robert Linnehan
