There is no measuring stick nor factor that can predict if the herpes simplex infection will recurr or not. A patient who knows that they have the virus must be alert in case the eye begins to show symptoms like red eye, discomfort, a gritty sensation or blurred vision. If this is the case, they should go to the ophthalmologist immediately to get a diagnosis and receive treatment as soon as possible so that the infection and inflammation leave as little corneal cicatrisation as possible.
