Figure Lengend Snippet: Evaluation of personalized biomimetic bio-cornea for short-term epithelial repair in large corneal defects in vivo . A) Representative corneal images before treatment, immediately after operation, and at 3, 7, 14, and 28 days post-OP (bright-field and fluorescein staining). B) Time-course of epithelialization percentage for each group (n = 5). C) Representative AS-OCT images and measurements of corneal and epithelial thickness immediately post-OP and 28 days post-OP. The white arrow shows transplanted bio-corneas. The red line shows the boundary. The red arrow shows the scar formed at 28 days post-OP. D) Statistical analysis of corneal thickness at 28 days post-OP (n = 5). E) Statistical analysis of epithelial thickness at 28 days post-OP (n = 5). Data in B), D) and E) are presented as mean ± SD. ns, no significant difference, # p < 0.05, ## p < 0.01 compared to the DBC group; ∗ p < 0.05, ∗∗ p < 0.01, ∗∗∗ p < 0.001 compared to the injury group. ST, immediately after operation; OP, operation.

Article Snippet: The examinations at each time point included slit-lamp biomicroscopy (S360, MediWork, CHN) to observe and perform anterior segment photography, anterior segment optical coherence tomography (AS-OCT) examination (RTVue-100, Optovue Inc., USA) to assess the in vivo status of the cornea and the regularity of the corneal anterior surface, and corneal topography (Pentacam HR, Oculus, GER) to detect corneal morphology, including corneal thickness and changes in the anterior surface curvature.

Techniques: In Vivo, Staining

Article Title: Refractive outcomes after cataract surgery in eyes with pterygium: validation of a regression-based keratometric prediction model

doi: 10.3389/fopht.2026.1759853

Figure Lengend Snippet: Measurement of horizontal pterygium size (HPS) using CASIA2. A horizontal corneal cross-section obtained with the CASIA2 anterior segment OCT system is shown. The pterygium distance (A) was defined as the perpendicular distance from the nasal angle recess to a vertical line (B) drawn from the apex of the pterygium. HPS was calculated by dividing this distance by the horizontal angle-to-angle distance (C) .
