Keratoconus results in a rare complication called corneal hydrops. Hydrops occurs when the inner corneal layer (endothelium) ruptures and fills with fluid. This results in cloudiness and swelling of the cornea. Hydrops can be managed by instilling antibiotic or steroidal eye drops to prevent infection, relieve pain and discomfort. In time, the endothelial pump cells will remove the fluid from the cornea.
