Topical retinoic acid: Application of a topical ointment containing retinoic acid three times a day is often considered to be one of the most effective treatments for healing corneal lesions.
Vitamin A supplements: A systemic therapy comprising vitamin A supplements like a single prophylactic oral dose of retinyl palmitate may be prescribed by your doctor.
Intramuscular injection: Injections containing water-miscible retinyl palmitate might be prescribed, although it may cause side effects like vomiting.
Topical artificial tears: This may help in keeping the eyes lubricated, thus, preventing dryness.
Wrap around glasses: This prevents air from coming in contact with the cornea, preventing it from drying up.
Air humidifier: Air humidifier keeps the cornea moist, again preventing dryness.
