    1. Intraoperative changes in corneal structure during excimer laser phototherapeutic keratectomy (PTK) assessed by intraoperative optical coherence tomography

      Intraoperative changes in corneal structure during excimer laser phototherapeutic keratectomy (PTK) assessed by intraoperative optical coherence tomography

      Purpose Excimer laser phototherapeutic keratectomy (PTK) is a safe treatment for superficial corneal opacities, e.g., in corneal dystrophies or degenerations. Nevertheless, no standardized treatment protocols are available and intraoperative monitoring was not possible, so far. Here we evaluate the potential benefits of the intraoperative assessment by microscope-integrated intraoperative optical coherence tomography (MI-OCT) of corneal optical properties during PTK. Methods Retrospective study of eight patients (one male, seven females; age range, 43–80 years, mean = 66.1 years) using an 840-nm microscope-integrated spectral-domain OCT (iOCT; OptoMedical Technologies, Luebeck, Germany adapted to HS Hi-R Neo 900A, Haag Streit Surgical, Wedel, Germany ...

    2. Anterior Segment Optical Coherence Tomography for the Diagnosis of Corneal Dystrophies according to the IC3D Classification

      Anterior Segment Optical Coherence Tomography for the Diagnosis of Corneal Dystrophies according to the IC3D Classification

      Corneal dystrophies are categorized according to the International Committee for Classification of Corneal Dystrophies (IC3D) classification, and their treatment depends on the affected structures and layer of the cornea. Therefore, estimating the depth and extent of the morphological changes due to the specific dystrophy is crucial when deciding between different treatment options. Besides superficial laser treatments and penetrating keratoplasty, minimal invasive lamellar keratoplasties such as Descemet membrane endothelial keratoplasty), deep anterior lamellar keratoplasty, or Descemet stripping automated keratoplasty have become increasingly popular to exchange the specific opaque layers in dystrophic eyes. To determine the morphological changes of the cornea in ...

    3. Intraoperative Optical Coherence Tomography in Lamellar Keratoplasties: Indications and Outcomes

      Intraoperative Optical Coherence Tomography in Lamellar Keratoplasties: Indications and Outcomes

      Purpose of Review Lamellar keratoplasties are evolving techniques to selectively replace diseased or opacified layers of the cornea. In recent years, the popularity of lamellar keratoplasties, especially Descemet membrane endothelial keratoplasty, Descemet stripping-automated endothelial keratoplasty and deep anterior lamellar keratoplasty, increased dramatically, since lamellar surgeries reduce intra- and postoperative complications and achieve faster visual recovery. Nonetheless, the surgical procedures are delicate. Recent Findings Novel imaging techniques, as intraoperative optical coherence tomography (OCT), may substantially help standardize these procedures to even further reduce intra- and postoperative complications and potentially improve outcome. Summary The present review summarizes the current literature regarding the ...
