Post corneal transplant treatment
Corneal transplants are an extremely successful procedure for restoring vision for a variety of diseases. However, patients can sometimes experience reduced vision or a need for complex contact lenses after corneal transplant procedures. Many of the causes for this reduction in vision can be corrected with excimer laser treatment.
After a corneal graft the front of the eye may have an irregular shape called Irregular astigmatism. A specialised machine called a topographer can measure this abnormal shape and use this information to guide a customised laser treatment called topography guided photo therapeutic keratectomy PTK. This treatment can help patients to get out of contacts, improve their quality of vision and reduce visual symptoms such as starbursts, haloes and glare.
Untreated Fuchs’ Endothelial Dystrophy with long term corneal oedema can lead to scarring on the very front surface of the cornea. The standard treatment for this disease is an endothelial corneal graft that gets rid of the oedema, but the scarring may remain and limit the vision. This sub-epithelial scarring can be very safely and effectively removed with our laser.
