Conditions We Treat
Recurrent Corneal Erosion Syndrome
Recurrent corneal erosion syndrome happens when the surface layer of the cornea — the epithelium — repeatedly peels away because it doesn't adhere firmly to the tissue beneath it. The result is sudden, sharp eye pain that tends to recur, classically when you first open your eyes in the morning.
Why it happens
There are two common causes. The first is a previous corneal abrasion — a scratch from a fingernail, a piece of paper, or a tree branch — that healed without forming a strong bond to the underlying layer. The second is an underlying corneal dystrophy, most often epithelial basement membrane dystrophy (also called map-dot-fingerprint dystrophy), in which the "glue" that anchors the epithelium is abnormal. In both cases the loose surface can tear away again and again.
The classic story
During sleep the eyelid can stick to the loose epithelium; when you open your eye in the morning, it pulls the surface off, causing:
- Sudden, sharp eye pain — often on waking or in the middle of the night
- Tearing and light sensitivity
- Blurred vision and a strong foreign-body sensation
- Redness, with episodes that come and go over weeks to years
How we treat it
Most erosions respond well to treatment, starting conservatively and escalating only if needed:
- Intensive lubrication — artificial tears through the day and a lubricating ointment at bedtime, often continued for several months to give the surface time to bond firmly.
- Hypertonic (salt) drops or ointment to draw excess fluid out of the surface and improve adhesion.
- Bandage contact lens to protect the cornea and relieve pain while it heals.
- In-office and laser procedures for stubborn cases:
- Epithelial debridement — gently removing the loose epithelium so a healthier layer can re-adhere.
- Anterior stromal puncture — tiny micro-punctures that create strong adhesion points, used outside the central visual area.
- Phototherapeutic keratectomy (PTK) — an excimer-laser treatment that smooths the surface and promotes durable re-adhesion; it is highly effective for recurrent erosions, especially those from a dystrophy.
If you have repeated bouts of morning eye pain or a known "scratch that never quite healed," an exam can confirm recurrent erosion and match you to the simplest treatment that will stop the cycle.
