We tested a 1310-nm optical coherence tomograph coupled with a beam splitter on the front lens of an operating microscope for intraoperative, noncontact visualization of anterior segment procedures. This new modification of optical coherence tomography technology allows intraoperative, high-resolution, cross-sectional imaging and pachymetry of the cornea and sclera during anterior segment surgery. It is particularly helpful for lamellar dissection techniques such as deep anterior lamellar keratoplasty and trabeculectomy.
