 Due to restraints in the size and structure of the imaging equipment, the use of OCT in the operating room has been limited. More recently, modifications to OCT table-top models as well as the development of hand-held OCT probes have allowed for the translation of OCT technology into the operating room. The high resolution anatomic information that is gained from OCT imaging is a natural complement to the ophthalmic surgeon. Using OCT during vitreoretinal surgery has revealed subtle changes in the microarchitecture of the retina in diseases such as retinal detachment, macular hole, and optic pit, that were not previously known. Using OCT during lamellar corneal transplant procedures, anterior segment surgeons have been able to image proper placement of the graft that was previously unattainable with a standard surgical microscopic view.
