Laser‐Assisted In Situ Keratomileusis Surgery on a Patient with Myelin Oligodendrocyte Glycoprotein Antibody‐Associated Disease or Neuromyelitis Optica Spectrum Disorder

Case Reports in Ophthalmological Medicine, Volume 2023, Issue 1, 2023., 2023
Myelin oligodendrocyte glycoprotein antibody‐associated disease (MOGAD) and neuromyelitis optica spectrum disorder (NMOSD) are rare central demyelinating diseases that may affect refractive surgery outcomes. Optic neuritis and brainstem syndromes affecting cranial nerves are particularly relevant to corneal refractive surgery (CRS), such as laser ...

Corneal Asphericity and Higher‐Order Aberrations after FS‐LASIK and Trans‐PRK for Myopia

Journal of Ophthalmology, Volume 2021, Issue 1, 2021., 2021
Objective. To compare the corneal asphericity and higher‐order aberrations (HOAs) of femtosecond laser‐assisted in situ keratomileusis (FS‐LASIK) with Smart Pulse Technology (SPT) assisted transepithelial photorefractive keratectomy (Trans‐PRK) for myopia and myopic astigmatism correction. Methods. This prospective study analyzed 88 eyes of 44 patients

Preliminary Characterization of Predictive Factors of the Visual Change after Epi‐On and Epi‐Off Corneal Collagen Crosslinking Techniques

Journal of Ophthalmology, Volume 2021, Issue 1, 2021., 2021
Purpose. To investigate the potential predictive factors of the visual change achieved with accelerated epi‐on and epi‐off corneal collagen crosslinking (CXL) in keratoconus. Methods. This retrospective comparative study analyzed 67 eyes treated with an accelerated epithelium‐on (epi‐on group) and epithelium‐off (epi‐off group) CXL.

Combined corneal CXL and photorefractive keratectomy for treatment of keratoconus: a review [PDF]

International Journal of Ophthalmology, 2019
Keratoconus and iatrogenic keratectasia are the corneal ectatic disorders occurring due to biomechanical weakening of the cornea resulting in distorted images, myopia, and irregular astigmatism. Corneal collagen cross-linking (CXL) is performed to arrest
