Recurrent Corneal Erosions: Why Your Eye Pain Keeps Coming Back

Waking up with sharp eye pain can be scary—especially when it feels like something is scratching your eye, but you do not remember getting anything in it. For some patients, this can happen more than once. One possible cause is recurrent corneal erosion, also called RCE.
A recurrent corneal erosion happens when the thin surface layer of the cornea does not stay attached properly. The cornea is the clear front window of the eye. When that surface layer loosens or breaks open, it can feel like a fresh scratch on the eye.
What Does a Recurrent Corneal Erosion Feel Like?
Many patients describe it as sudden, sharp pain when they first wake up or open their eyes in the morning. Symptoms may include:
Sharp eye pain
Tearing
Redness
Light sensitivity
Blurry vision
A gritty or foreign body sensation
Feeling like the eyelid is “stuck” to the eye
Morning symptoms are common because the eyelid can stick to the dry corneal surface overnight. When the eye opens, it may pull the loose surface cells away again.
Why Does It Keep Happening?
A recurrent corneal erosion often starts after a previous corneal injury. This could be something like a fingernail scratch, paper cut, makeup brush injury, or plant/leaf trauma. Even after the original scratch seems healed, the new surface cells may not anchor firmly to the deeper corneal layer.
Some patients also have an underlying corneal condition, such as epithelial basement membrane dystrophy, where the corneal surface naturally has weaker attachment points. This can make the eye more prone to repeated erosions even without a major injury. Clinical sources describe recurrent corneal erosion as repeated breakdown of the corneal epithelium, commonly associated with prior trauma or corneal dystrophy.
Why It Can Be Worse in the Morning
While sleeping, the eyes may become slightly dry. If the corneal surface is unstable, the eyelid can adhere to the healing area. When the patient opens the eye, the surface can tear open again.
That is why many treatment plans focus heavily on nighttime lubrication and keeping the corneal surface protected while sleeping.
How an Eye Doctor Diagnoses It
During an eye exam, the doctor may use a microscope called a slit lamp and a special yellow dye called fluorescein. This helps highlight areas where the corneal surface is irregular, loose, or missing.
Sometimes the erosion is obvious. Other times, the eye may look mostly healed by the time the patient comes in, but the history of repeated morning pain gives an important clue.
Treatment Options for Recurrent Corneal Erosions
Treatment depends on how severe the erosion is and how often it happens.
1. Lubricating Drops and Ointments
For mild cases, preservative-free artificial tears during the day and a thicker ointment at bedtime may help protect the cornea. Hypertonic saline drops or ointment may also be recommended to help reduce corneal swelling and improve surface stability. Conservative treatment commonly includes preservative-free lubrication and nighttime lubricating or hypertonic saline ointment.
2. Antibiotic Drops or Ointment
If the corneal surface is open, an antibiotic may be prescribed to reduce the risk of infection while the eye heals. This is especially important because an epithelial defect leaves the cornea more vulnerable.
3. Bandage Contact Lens
A bandage contact lens may be placed on the eye to act like a protective shield. It helps reduce pain, protects the healing surface, and allows the eyelid to glide over the cornea more smoothly. Bandage contact lenses are commonly used as a protective treatment option for recurrent erosions.
4. Anti-inflammatory Treatment
In some recurrent cases, the doctor may use anti-inflammatory drops or oral medications to reduce inflammation and help the cornea heal more securely. Some clinical reviews describe treatment approaches that include oral tetracycline-type medications and topical steroids in selected patients.
5. In-office Procedures
If erosions keep coming back despite drops, ointments, and bandage contact lenses, the doctor may discuss procedures to help the surface layer attach more firmly. These can include anterior stromal puncture, epithelial debridement, alcohol delamination, or phototherapeutic keratectomy, depending on the location and severity of the erosion.
What Patients Can Do at Home
Patients should not try to “tough it out” if the pain is severe or recurrent. However, prevention often includes a consistent home routine:
Use artificial tears during the day if the eyes feel dry. Use the recommended ointment at bedtime. Avoid rubbing the eyes. Treat dry eye, blepharitis, or eyelid inflammation if your doctor identifies it. Follow the full treatment plan even after the eye starts to feel better, because the cornea may still be strengthening underneath the surface.
When to Call the Eye Doctor
Call an eye doctor promptly if you have sudden eye pain, light sensitivity, redness, blurred vision, or the feeling that something is stuck in your eye. You should also be seen if the same eye pain keeps happening when you wake up.
A recurrent corneal erosion can feel like “just another scratch,” but repeated episodes may need a more targeted treatment plan to prevent the cycle from continuing.
The Bottom Line
Recurrent corneal erosions happen when the corneal surface does not stay attached the way it should. They often cause sharp morning eye pain, tearing, redness, and light sensitivity. The good news is that many cases improve with the right combination of lubrication, medication, protection, and long-term prevention.
If your eye keeps feeling scratched when you wake up, it may not be random dryness. It may be a recurrent corneal erosion—and an eye exam can help confirm the cause and guide the right treatment.
