To image stromal changes after corneal surgery using Fourier-domain optical coherence tomography (FD-OCT) with anterior segment adaptor.
Twelve patients undergoing corneal transplantation or refractive surgery at Asahikawa Medical College were included. Previous surgeries included deep lamellar keratoplasty (DLKP), penetrating keratoplasty, laser in situ keratomileusis (LASIK), and photorefractive keratectomy (PRK). FD-OCT (RTVue-100, Optovue, CA) with anterior segment adaptor was used to evaluate the cornea and anterior chamber postoperatively. The OCT images were compared to slit-lamp microscopy and topographic images using a corneal topographer (Pentacam, Oculus, Germany).
FD-OCT with anterior segment adaptor is a noncontact, noninvasive technique that can be performed safely after corneal surgeries. The images clearly showed various postoperative corneal conditions, e.g., host-graft gaps in eyes that underwent corneal transplantation, deep stromal opacities after DLKP, and superficial stromal opacity after PRK.
FD-OCT with anterior segment adaptor provides valuable images to evaluate outcomes after corneal surgery. OCT images have potential to assess the process of corneal wound healing after surgeries and manage surgical complications.
