Visualization during surgery continues to evolve

Intraoperative OCT is showing promise as a useful adjunct, especially in vitrectomy and lamellar keratoplasty. However, indications are limited, as vitrectomy only represents about 2% of ophthalmic surgical procedures in the U.S., or about 250,000 procedures per year. Endothelial and lamellar anterior keratoplasty represent only 0.25% of procedures, or about 30,000 per year.In vitrectomy, early adopter surgeons are finding intraoperative OCT helpful when peeling epiretinal membranes and treating other vitreoretinal interface pathologies. Intraoperative OCT can help differentiate retinoschisis from retinal detachment. It is also potentially helpful in select surgical procedures to repair macular hole and retinal detachment and treat retinopathy of prematurity. In particular, those vitreoretinal surgeons who are training residents and fellows have found it to be a valuable teaching tool. For the corneal surgeon, it can help scan for interface fluid and delineate tissue planes in Descemet’s stripping endothelial keratoplasty, Descemet’s membrane endothelial keratoplasty, pre-Descemet’s endothelial keratoplasty and deep anterior lamellar keratoplasty.
