Values of refractive error, corneal curvature, astigmatism and central thickness.
, 2013 SE = refractive error and converted to spherical equivalent, Km = mean corneal curvature (the mean of corneal curvature in horizontal and vertical axis); CA = corneal astigmatism (the difference between corneal curvature in horizontal and vertical axis);

Journal of Biophotonics, Volume 19, Issue 10, October 2026.Compared with single‐photon methods, TPM enables deep‐tissue imaging using near‐infrared light, with excitation confined to the focal plane, thereby reducing photodamage. SHG microscopy images noncentrosymmetric biological structures such as collagen and myosin without fluorescent labels, offering direct structural contrast.

Longitudinal assessment of the progression of severe keratoconus based on corneal topography
Scientific ReportsWe aimed to assess long-term disease progression in patients with severe keratoconus (KC). Clinical records of 125 patients (201 eyes) with severe KC followed-up for > 12 months were retrospectively analyzed.

Forme Fruste Keratoconus Imaging and Validation via Novel Multi-Spot Reflection Topography
Case Reports in Ophthalmology, 2013 Background/Aims: This case report aims to evaluate safety, efficacy and applicability of anterior surface imaging in a patient with forme fruste keratoconus (FFKC) based on a novel multi-spot, multicolor light-emitting-diode (LED) tear film-reflection ...

MedComm, Volume 7, Issue 10, October 2026.Our study reveals a novel mechanism by which MSC‐derived EVs alleviate NaIO3‐induced dry AMD‐like pathology. MSC‐EVs deliver miR‐486‐3p into retinal cells to directly inhibit the ferroptosis‐promoting target gene Lcn2. Concurrently, downregulated Lcn2 restores intracellular Gpx4 expression, thereby suppressing ferroptosis and rescuing retinal ...

A steep peripheral ring in irregular cornea topography, real or an instrument error? [PDF]
, 2016 PurposeTo demonstrate that the steep peripheral ring (red zone) on corneal topography after myopic laser in situ keratomileusis (LASIK) could possibly due to instrument error and not always to a real increase in corneal curvature.MethodsA spherical model
