Diffuse lamellar keratitis after femtosecond laser refractive lenticule extraction

JCRS Online Case Reports, 2013
We report 6 eyes (spherical refraction from −4.0 to −10.0 diopters) in 4 cases of diffuse lamellar keratitis (DLK) after femtosecond laser refractive lenticule extraction. A refractive lenticule was created using a femtosecond laser and then extracted through a 3.0 mm incision (5 eyes without a flap) and an approximately 20.0 mm incision (1 eye, flap ...

Evaluation of Corneal Irregular Astigmatism and Visual Quality Following Bilateral Sequential SMILE and LASEK: A Six‐Year Comparative Study

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To compare the corneal spherical component (SC), regular astigmatism (RA), irregular astigmatism (IA, including asymmetry and irregularity), and visual quality 6 years after small incision lenticule extraction (SMILE) and laser subepithelial keratomileusis (LASEK) for mild‐to‐moderate myopia.

Artificial Cornea Substitute Based on Hydrogel Skeletons with Natural Stromal Hierarchical Structure and Extracellular Matrix for Sutureless Transplantation

Advanced Science, Volume 12, Issue 19, May 22, 2025.
Humanized corneal stroma‐like adhesive patches (HCSPs) are developed for lamellar keratoplasty and corneal perforation repair. HCSPs exhibit histological, optical, and biomechanical characteristics similar to those of the natural cornea, with improved wet tissue adhesion, anti‐degradation, and anti‐swelling capabilities compared to conventional tissue ...

Assessing UVA and Laser‐Induced Crosslinking via Brillouin Microscopy

Journal of Biophotonics, Volume 18, Issue 5, May 2025.
UVA crosslinking is the primary treatment to combat keratoconus. Nevertheless, unwanted side effects and limitations due to nonselective irradiation lead to the investigation of alternative irradiation treatments. This study shows similar changes in the Brillouin frequency shift of corneas crosslinked with UVA irradiation and a NIR femtosecond laser ...

Miopía Alta: definición, comorbilidad y corrección refractiva. Revisión bibliográfica [PDF]

, 2019
La definición Miopía Alta es un tema controvertido pues no hay consenso en la definición del umbral de equivalente esférico y/o longitud axial. La miopía, y especialmente la miopía alta, induce cambios en el ojo asociando comorbilidad que puede ...
