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.
Accurate detection of post-refractive ectasia susceptibility is essential during preoperative evaluation for laser vision correction (LVC) due to the risk of progressive corneal ectasia and vision decline post-surgery. Despite improved screening and a reduced incidence from 0.66 to 0.

- * Researchers analyzed data from 1,220 patients with HCV-related cirrhosis, creating a risk model using factors like PIVKA-II levels, age, sex, and liver function markers.
- * The model demonstrated good accuracy in distinguishing HCC risk, with low, medium, and high-risk groups showing cumulative incidence rates of 2.7%, 4.0%, and 14.3%
Purpose: The aim of this study was to characterize the corneal layer thickness profile in different stages of keratoconus (KC).
Methods: Patients with clinical or subclinical KC without a history of contact lens use were retrospectively enrolled. We evaluated 164 eyes, including 69 clinical KC, 32 topographic KC (no clinical signs), 22 very asymmetric ectasia with normal topography and no clinical signs of ectasia (VAE-NT), and 41 control eyes.
