What is a corneal transplant? The cornea is the clear window at the front of the eye and it’s really important for focusing vision to the back of the eye. Now, in some patients, either the cornea loses shape progressively or suddenly if there’s some trauma to the eye or the cornea loses clarity because the delicate cells that line the inside of the cornea start to degrade in terms of number of quality.
When we consider performing a corneal transplant, it’s usually after having tried other measures such as glasses or contact lenses to try to restore vision. But when it does become necessary, we then cancel the patient regarding taking donor cornea and transplanting that into the eye of the patient.
The risk of that with modern techniques are relatively low, but for some patients, there is still a risk of vision as a result of complications such as rejection of the transplant.
Modern techniques try to restore only the layers of the cornea that need to be transplanted in order to restore vision and these modern techniques are even more effective and safe than those that have gone before.
Ultimately, patients may still require glasses and contact lenses to see and a few patients will still require long-term management of the corneal transplant and drops to ensure that the transplant stays healthy.
