A corneal ulcer, by definition, is an area of inflamed cornea where the surface layer of cells (epithelium) has broken down to leave a 'raw' surface. As such, there are many kinds of and causes of corneal ulcers.
One of the most common kinds of corneal ulcers are those that are related to an infection associated with contact lens wear.
These kinds of ulcers require intensive antibiotic eyedrop use, usually starting off with one drop every hour of the day. That sometimes can mean 24 drops a day, ie eyedrops day and night around the clock, if it is severe enough. The patient also has to stop wearing contact lenses.
However, just to re-iterate, there is no one way to treat corneal ulcers because there are different kinds of corneal ulcers. If you have a corneal ulcer or you think you may have a corneal ulcer, the best thing is to see an eye doctor straight away.
