Bullous keratopathy is a condition in which the cornea becomes permanently swollen. This occurs because the inner layer of the cornea, the endothelium, has been damaged and is not pumping fluid properly .
The cause of the endothelial damage could be from trauma, glaucoma, or inflammation after eye surgery. Twenty years ago, the most common reason for bullous keratopathy was complications from cataract surgery with or without problems from intra-ocular lenses.Certain intraocular lens implant designs can damage the cornea.
Sometimes it is helpful to replace a lens implant with a newer design when a transplant is being performed to prevent damage to the transplant.Endothelial keratoplasty (EK) is the recommended treatment for bullous keratopathy.
