The discomfort (light sensitivity, foreign body sensation, tearing, redness, swelling) usually lasts between 3 to 5 days. This ceases once the corneal epithelium has fully repopulated the surface of the cornea. The bandage contact lens allows proper repopulation of the corneal epithelium. Once there is complete reepithelialization, the corneal nerves are no longer exposed, therefore, the discomfort stops.
