Comparison of clinical outcomes between wavefront-optimized versus corneal wavefront-guided transepithelial photorefractive keratectomy for myopic astigmatism

, 2017
PURPOSE: To evaluate and compare the clinical outcomes, including visual acuity, refractive errors, and aberrations, between aberration-free transepithelial photorefractive keratectomy (PRK) and corneal wavefront-guided transepithelial PRK in eyes with ...

Understanding higher‐order aberrations in keratoconus

Optometry and Vision Science, Volume 103, Issue 10, October 2026.
ABSTRACT Keratoconus is characterized by progressive thinning and increasing irregularity of the cornea, leading to substantial degradation in optical quality through the induction of both lower‐ and higher‐order aberrations (HOAs). In addition to inducing myopic and astigmatic refractive error, asymmetric corneal steepening generates complex optical ...

Corneal power modelling with OCT data – Thin and thick lens paraxial models versus raytracing

Acta Ophthalmologica, Volume 104, Issue 5, Page 498-509, August 2026.
Abstract Background Evaluating keratometric power with Zeiss index (PKZ), paraxial thick cornea power (Gullstrand [PG]) and power referenced to the front (PFV) and back vertex plane (PBV) and raytracing power (PR), and modelling the deviation from PKZ with a multivariable linear prediction model.

Cell Mechanics in Cancer: Integrating Mechanotransduction Pathways Within the Tumor Microenvironment

Journal of Cellular Physiology, Volume 241, Issue 5, May 2026.
ABSTRACT Single‐cell mechanical properties such as stiffness, elasticity, and viscosity, are crucial in governing biological processes like migration, proliferation, and differentiation. In cancer, the mechanical properties of cells undergo significant alterations, which contribute to tumor growth, metastasis, and resistance to therapy.

Changes in corneal wavefront aberrations with aging.

Investigative ophthalmology & visual science, 1999
To investigate whether corneal wavefront aberrations vary with aging.One hundred two eyes of 102 normal subjects were evaluated with videokeratography. The data were decomposed using Taylor and Zernike polynomials to calculate the monochromatic aberrations of the cornea for both small (3-mm) and large (7-mm) pupils.For a 3-mm pupil, the amount of total

Immediate Postoperative Decentration of a Biologic Corneal Inlay Managed With Tomography‐Guided Repositioning: A Case Report

Clinical Case Reports, Volume 14, Issue 3, March 2026.
Immediate postoperative Pentacam corneal tomography revealing inferior‐temporal decentration of the biologic corneal inlay on the axial curvature map. ABSTRACT Biologic corneal inlays can rarely present with immediate postoperative decentration, which can be subtle and difficult to detect clinically. Real‐time tomography allows precise early diagnosis,

Dynamic Retinal Pathology in Glaucoma Progression Revealed by High‐Resolution Functional Imaging In Vivo

Laser &Photonics Reviews, Volume 20, Issue 5, 6 March 2026.
In this work, we investigated the dynamic retinal pathology of glaucoma from onset to late stages through longitudinal in vivo high‐resolution imaging in a silicone oil‐induced ocular hypertension (SOHU) glaucoma mouse model. We developed an optimized adaptive optics two‐photon excitation fluorescence microscopy (AO‐TPEFM) technique for morphological ...
