If the corneal abrasion was restricted to the epithelial layer and there is no infection, there probably won’t be any consequences to your vision. But if the abrasion was deeper and affected the sub-epithelial layer, a scar on the cornea will be formed as a permanent consequence. Scars on the cornea will permanently damage the vision on the affected eye. A corneal scar and permanent vision damage will also occur if a corneal abrasion, no mater the depth, is complicated with an infection. There is nothing you can do except to follow doctor’s instructions for preventing infection. Recovery time and eventual consequences to the vision depends upon the severity of the abrasion and eventual complications.
