The Cornea Research Group focuses on research relating to several aspects of corneal/refractive surgery. This includes understanding corneal wound healing following laser refractive surgery (i.e. using excimer and femtosecond lasers, assessing the wound healing response following many refractive procedures, e.g. LASIK/SMILE/Presbyopia surgery).
The corneal research is mainly focused on developing techniques of selective cellular therapy such as corneal endothelial cell therapy and stromal cell therapy. The team works on developing and optimising culture protocols, and translating these therapies to preclinical animal models and clinical trials.
Corneal Transplantation – assessing clinical outcomes following corneal transplantation using cohort data from the SCTS
Laser Wound Healing – wound healing responses following femtosecond laser corneal surgery for refractive and corneal transplantation, assessing wound healing following lenticule re-implantation, assessing lenticule integration
Improvement Outcomes in KPro Design – surface coating to improve adhesion following KPro surgery, reducing infective rates following KPro Surgery
Corneal Endothelial Cell Therapy – investigating transportation of cells for clinical delivery, assessing the efficacy of cells for different delivery systems, QC of GMP modified cells, assessing the efficacy of different carrier systems for cell delivery, development of humanised s-PRDx6 for optimisation of cell delivery, development of culture systems for endothelial stem cells
Stromal Cell Therapy – optimisation of protocols for expansion of corneal keratocytes, assessing models of delivery of these cells, efficacy of the cells for stromal therapy
Corneal Gene Therapy – assessing the effects of Cas 9 therapy patients with FECD, optimisation of vector delivery systems
