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 ... -
Laser In Situ Keratomileusis (LASIK) Combined with Prophylactic Corneal Cross-Linking for Correction of Myopia: Regional Analysis of Corneal Morphology
Zhang, Jia; Chen, Tong; Wang, Junjie; Bao, Fangjun; Chen, Wen; Stojanovic, Aleksandar; Wang, Qinmei; Chen, Shihao (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-09)Introduction: This study evaluated the outcomes of laser in situ keratomileusis (LASIK) combined with prophylactic corneal collagen cross-linking (CXL) in correcting myopia in cases with increased estimated risk of postoperative corneal ectasia, detected by regional analysis of corneal morphology.<p> <p>Methods: The retrospective study included 180 eyes of 99 patients. Group 1 (94 eyes of ... -
Safety and efficacy of epithelium-on corneal collagen cross-linking using a multifactorial approach to achieve proper stromal riboflavin saturation
Stojanovic, Aleksandar; Chen, Xiangjun; Jin, Nan; Zhang, Ting; Stojanovic, Filip; Ræder, Sten; Utheim, Tor Paaske (Journal article; Tidsskriftartikkel; Peer reviewed, 2012-07-30)Purpose. To evaluate the efficacy and safety of epithelium-on corneal collagen cross-linking (CXL) using a multifactorial approach to achieve proper stromal riboflavin saturation. Methods. This non-randomized retrospective study comprised 61 eyes with progressive keratoconus treated with epithelium-on CXL. Chemical epithelial penetration enhancement (benzalkonium chloride-containing local medication ...
