Topographical and Refractive Outcomes After Corneal Cross-linking in Novice Scleral Lens Users.
Eye Contact Lens
January 2025
Lewis Katz School of Medicine at Temple University (F.A.), Philadelphia, PA; and Wilmer Eye Institute (L.D.M., K.B., A.C.), Baltimore, MD.
Objective: To determine if scleral fittings that occur before corneal cross-linking (CXL) are still successful after the procedure.
Methods: This prospective study included seven patients with keratoconus or post-laser-assisted in situ keratomileusis (LASIK) corneal ectasia who were fitted with scleral lenses then underwent CXL. Four patients (six eyes) had keratoconus and three patients (five eyes) had post-LASIK ectasia.
Unilateral Corneal Ectasia After Bilateral Transepithelial Photorefractive Keratectomy.

We present the case of a 23-year-old male who experienced vision loss in his left eye 15 months after undergoing bilateral transepithelial photorefractive keratectomy (T-PRK). Despite the absence of any significant preoperative topographical risk factors in either eye, corneal ectasia was later confirmed in the left eye, while the right eye remained normal. Subtle asymmetry in topometric indices and a borderline high Index of vertical asymmetry (IVA) reading suggested the possibility of early subclinical keratoconus, potentially increasing the risk of post-refractive ectasia.

Keratoconus is a progressive corneal ectasia that may lead to severe visual impairment. Superior keratoconus (SK) is an uncommon form of the disease, and few cases have been reported thus far. We present an unusual SK case and a literature review of this rare diagnosis.

Jpn J Ophthalmol
January 2025
Department of Ophthalmology, Osaka University Graduate School of Medicine, 2-2 Yamadaoka, Suita, Osaka, 565-0871, Japan.
Purpose: To determine whether corneal biomechanical parameters can predict ectasia progression.
Study Design: Retrospective observational study.
Methods: The baseline corneal biomechanical parameters of 64 eyes of 41 young patients (age, < 25 years at the first visit) who were diagnosed with keratoconus (KC) or suspected KC at Osaka University Hospital and followed up for more than two years were reviewed.
Application of Surgical Protocols for the Treatment of Highly Irregular Astigmatism with Topographic Guided Ablation in a Case of Post-LASIK Ectasia.
Int Med Case Rep J
January 2025
Department of Ophthalmology, University of California San Francisco, San Francisco, CA, USA.
Purpose: To compare the outcomes of two different surgical planning strategies for topography-guided repair of post-LASIK ectasia.
Methods: This is a case report of a patient presenting with post-LASIK ectasia. A retrospective chart review was used to collect details of the ophthalmic exam, as well as ocular imaging such as anterior segment optical coherence tomography and Scheimpflug corneal tomography.
