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 ...

Post-keratoplasty glaucoma [PDF]

, 2015
Post-keratoplasty glaucoma (PKG) remains one of the leading causes of blindness due to the loss of optic nerve fibers and irreversible graft opacification. PKG is a challenge due to diagnostic and therapeutic difficulties and recalcitrant course.

Genotype–Phenotype Correlations in Corneal Dystrophies: Advances in Molecular Genetics and Therapeutic Insights

Clinical &Experimental Ophthalmology, Volume 53, Issue 3, Page 232-245, April 2025.
ABSTRACT Corneal dystrophies are a group of predominantly rare inherited disorders. They are by definition bilateral, relatively symmetrical, and without systemic involvement, affecting corneal transparency and/or refraction. Traditional classification of corneal dystrophies is based on slit‐lamp appearance, affected corneal layer and histological ...

Current Approaches for Management of Postpenetrating Keratoplasty Astigmatism [PDF]

, 2011
A successful corneal graft requires both clarity and an acceptable refraction. A clear corneal graft may be an optical failure if high astigmatism limits visual acuity.

Variation of Bruch's membrane opening in response to intraocular pressure change during scleral lens wear, in a population with keratoconus

Ophthalmic and Physiological Optics, Volume 45, Issue 2, Page 405-415, March 2025.
Abstract Purpose The present study aimed to determine the potential impact of scleral lenses on intraocular pressure (IOP) by analysing the Bruch's membrane opening–minimum rim width (BMO‐MRW) while the lenses are worn, in a population with keratoconus.

Individual Risk Assessment and Prognostication of Outcomes After Corneal Cross‐Linking

Journal of Ophthalmology, Volume 2025, Issue 1, 2025.
Background and Objective: Corneal collagen cross‐linking (CXL) is a treatment which arrests keratoconus (KC) progression, but its effectiveness differs radically among patients. Herein, we report preoperative diagnostic findings that reflect CXL outcomes and allow physicians to prognosticate treatment efficiency.

Biologicals and Biomaterials for Corneal Regeneration and Vision Restoration in Limbal Stem Cell Deficiency

Advanced Materials, Volume 36, Issue 42, October 17, 2024.
Scaffolds with stem cells to rehabilitate the ocular surface in patients with limbal stem cell deficiency. Native and synthetic scaffolds, as carriers of stem cells, are being developed and transplanted to treat individuals with limbal stem cell deficiency (LSCD). Successful outcomes include restoration of tissue architecture and improvements in ocular

Clinical outcomes of femtosecond laser‐assisted corneal allogenic intrastromal ring segment (CAIRS) in the treatment of keratoconus

Clinical &Experimental Ophthalmology, Volume 52, Issue 7, Page 713-723, September/October 2024.
Abstract Background To evaluate the results of corneal allogenic intrastromal ring segment (CAIRS) implantation in keratoconus. Methods The medical records of patients with keratoconus who underwent CAIRS implantation were reviewed. The CAIRS, prepared by trephination from the donor cornea, was implanted into a tunnel created using the femtosecond ...
