Corneal tissue procedures are evolving beyond full-thickness transplants into minimally invasive, layer-specific interventions. Key breakthroughs include Corneal Tissue Addition Keratoplasty (CTAK) and Corneal Allogenic Intrastromal Ring Segments (CAIRS) for treating ectasias, alongside bioengineered artificial constructs that solve donor shortages. [1, 2, 3]
Expanded Clinical Applications
Corneal Addition Techniques: Procedures like CTAK implant customized, irradiated donor tissue inlays to reshape the cornea. Similarly, CAIRS uses donor corneal tissue rather than rigid synthetic polymers to treat conditions like keratoconus. These procedures integrate seamlessly with native extracellular matrix without provoking a foreign-body inflammatory response. [1, 2, 3]
Bioengineered Endothelial Grafts: Advancements in regenerative biomaterials and cell culture systems have led to functional substitutes. These artificial grafts are used in methods similar to Descemet membrane endothelial keratoplasty (DMEK), helping to diminish immunologic risks while treating endothelial disease. [1]
Gene Therapy and Wound Modulation: Targeted therapies are being integrated with keratoplasty to deliver therapeutic genes directly to corneal cells. This approach aims to treat corneal dystrophies and control post-surgery wound healing. [1]
Stem Cell Therapy & Surface Reconstruction: Mesenchymal and epithelial stem cell treatments are expanding the scope of corneal regeneration, focusing on corneal nerve regeneration, pain management, and treating severe ocular surface diseases. [1, 2]
For ophthalmologists and surgeons exploring these advanced, layer-specific treatments, utilising the precision of the Femtosecond laser applications in corneal surgery ensures better reproducibility and localized intervention. [1, 2]
