    • Coma influence on manifest astigmatism in coma-dominant irregular corneal optics 

      Zhou, Wen; Stojanovic, Filip; Reinstein, Dan Z.; Archer, Timothy J.; Chen, Xiangjun; Feng, Yue; Stojanovic, Aleksandar (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-01)
      PURPOSE:To evaluate the influence of coma on manifest refractive cylinder (MRC) in eyes with coma-dominated corneal optics and suggest alternative guidelines for surgical planning of astigmatism correction in topography-guided ablation and toric intraocular lens (IOL) exchange surgery.<p> <p>METHODS:Twelve eyes with coma-dominant corneal optics and low lenticular astigmatism were selected. The ...
    • Epithelial Thickness Mapping in Keratoconic Corneas: Repeatability and Agreement Between CSO MS-39, Heidelberg Anterion, and Optovue Avanti OCT Devices 

      Feng, Yue; Reinstein, Dan Z.; Nitter, Tore; Archer, Timothy J.; McAlinden, Colm; Bertelsen, Geir; Stojanovic, Aleksandar (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-01)
      PURPOSE:To assess repeatability and agreement of corneal epithelial thickness mapping in eyes with keratoconus using three optical coherence tomography (OCT) devices featuring different technologies: spectral-domain (SD) OCT combined with Placido disk corneal topography (MS-39), swept-source OCT (Anterion), and SD-OCT (Avanti).<p> <p>METHODS:Three consecutive measurements were acquired with the ...
    • Heidelberg Anterion Swept-Source OCT Corneal Epithelial Thickness Mapping: Repeatability and Agreement With Optovue Avanti 

      Feng, Yue; Reinstein, Dan Z.; Nitter, Tore A.; Archer, Timothy J.; McAlinden, Colm; Chen, Xiangjun; Utheim, Tor Paaske; Bertelsen, Geir; Stojanovic, Aleksandar (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-01)
      <p><b> PURPOSE:</b> To assess the repeatability of corneal epithelial thickness mapping in virgin, post-laser refractive surgery (PLRS), and keratoconic eyes using a novel swept-source optical coherence tomographer (SS-OCT), and to determine the agreement of the measurements with a validated spectral-domain (SD) OCT. <p><b> METHODS:</b> Analysis of 90 virgin, 46 PLRS, and 122 keratoconic eyes ...
    • Intraoperative swept-source OCT–based corneal topography for measurement and analysis of stromal surface after epithelial removal 

      Zhou, Wen; Reinstein, Dan Z.; Archer, Timothy J.; Chen, Xiangjun; Utheim, Tor Paaske; Feng, Yue; Stojanovic, Aleksandar (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-01)
      <p>PURPOSE: To assess intraoperative stromal topography measurements using swept-source optical coherence tomography (OCT)–based topography/tomography after epithelial removal and to analyze the epithelial contribution to the corneal topography and optics. <p>METHODS: This was a prospective series of 22 eyes of 19 patients referred to receive phototherapeutic keratotomy (PTK) for treatment of ...
