How recurrent corneal erosion affects your eye
The cornea’s outer layer, the epithelium, is anchored to the tissue beneath it by a thin basement membrane. In recurrent corneal erosion, that anchor is weak. The epithelium heals over, then tears away again.
The classic pattern is sudden, sharp pain in one eye when you first wake up. Redness, light sensitivity, blurred vision, and watering often come with it. The pain may last minutes or hours, and longer in more severe episodes.[1] The usual explanation is that the eye dries overnight, the inside of the eyelid sticks to the loose surface, and opening the eye in the morning pulls the epithelium away.[1]
Most cases follow one of two things: an earlier injury to the surface of the cornea, or a condition in which the basement membrane is abnormal, such as epithelial basement membrane dystrophy. Other corneal dystrophies and degenerations, past eye surgery, and lid problems can also set it off.[1]
It is not rare. A study of emergency visits to Moorfields Eye Hospital in London estimated an annual incidence of 25.4 new cases per 100,000 people and a period prevalence of 0.96% over five years. The authors note that minor cases often heal before anyone examines them, so the true figure is likely higher.[2]
Where scleral lenses fit in
A scleral lens is a large rigid gas-permeable lens. It rests on the sclera (the white of the eye) and arches over the entire cornea without touching it. Before insertion it is filled with sterile saline, which sits between the lens and the cornea while it is worn.
While the lens is in, the blinking lid slides over the smooth lens instead of the fragile surface, and the cornea stays moist. The saline layer also smooths out an irregular corneal surface optically, which can give clearer vision if repeated erosions have left scarring.
But the timing is a problem. Scleral lenses are normally taken out before sleep. Erosions most often happen when you open your eyes after sleeping.[1] So a daytime scleral lens isn’t in the eye at the moment of greatest risk. Overnight protection usually comes from ointment, or from a soft bandage lens that your doctor places and monitors.
What the research shows
We found no published studies of scleral lenses for recurrent corneal erosion itself. A 2025 review of scleral lenses and PROSE lists recurrent corneal erosions among the conditions scleral lenses have been used for, but the evidence it cites for erosions is about contact lenses in general, not scleral lenses specifically.[6] The closest direct report is a case series of two people with a rare skin and eye condition called KID syndrome. One of them, an adult, wore a PROSE scleral device for seven years with resolution of recurrent erosions and a more stable corneal surface.[7] That is a different disease, and one person.
Because the scleral-specific evidence is so thin, the numbers on this page describe the treatments that are usually used for recurrent erosion.
Soft bandage lenses help some people, but not more than lubrication in one trial. In a randomized trial of 29 patients, symptoms resolved completely in 71% of those given a soft bandage contact lens for three months and 73% of those given lubricating drops and ointment. The bandage lens group felt better sooner, at about 5 weeks compared with 9.[3] In a separate small series of 12 patients whose erosions continued after at least 6 weeks of lubrication, 9 had no recurrence about a year after three months of extended-wear bandage lens.[4]
Simple procedures help many people who don’t respond to drops. In anterior stromal puncture, a fine needle makes tiny marks in the cornea to help the surface reattach. In a series of 35 eyes at one center, 62.9% were symptom-free at an average of 14 months, and the rest had milder episodes.[5] A 2019 review describes diamond burr polishing as the preferred treatment overall because of its low recurrence rate, and laser phototherapeutic keratectomy as an option for erosions in the center of the cornea.[1]
Other medical treatments exist for erosions that keep coming back. The same review describes oral medicines that block the enzymes loosening the surface, eye drops made from blood, amniotic membrane grafts, and short courses of steroid drops, used selectively. Once the surface has healed, a course of salty (hypertonic) drops or ointment is often used to help it stay down.[1] Your eye doctor will choose among these based on what is causing your erosions and how often they happen.
Recurrent erosion can come with other surface problems. People with meibomian gland dysfunction or ocular rosacea have higher levels of the enzymes involved and are at higher risk of erosions, and dry eye can coexist with them.[1] If your fitter is considering a scleral lens, it is often because of one of these other conditions, or because past erosions have left the cornea irregular, rather than for the erosions alone.
Other options, compared
Treatment for recurrent erosion usually goes in steps, starting with the simplest measures.[1]
| Option | What it does | Typically suited to |
|---|---|---|
| Lubricating drops, gels, and nighttime ointment | Keep the surface moist, especially overnight | The usual starting point |
| Soft bandage contact lens | Covers the cornea while it heals, sometimes worn for weeks | Erosions that keep returning despite lubrication |
| Oral or topical medicines | Reduce the enzymes and inflammation that loosen the surface | Selected cases, as prescribed |
| Anterior stromal puncture | Tiny needle marks help the surface reattach | Erosions outside the central line of sight |
| Diamond burr polishing | Smooths the layer beneath the epithelium | Erosions linked to basement membrane dystrophy |
| Phototherapeutic keratectomy (laser) | Removes a thin layer with an excimer laser | Central erosions not controlled by simpler steps |
| Scleral lenses | Hold saline over the cornea and shield it during the day | Selected cases with scarring, irregularity, or other surface disease |
Questions to ask a scleral lens fitter
- What would a scleral lens do for my erosions that my current treatment doesn’t?
- How will I protect my eye overnight while I wear a scleral lens during the day?
- How should I take the lens out to avoid disturbing a fragile surface?
- Should I see a cornea specialist about a procedure before trying a lens?
- What would make you advise stopping lens wear?
Common questions
Are scleral lenses a standard treatment for recurrent corneal erosion?
No. Standard care starts with lubricating drops and ointment, then soft bandage contact lenses and other medicines, then in-office procedures. Reviews of scleral lenses list recurrent erosion among the conditions they have been used for, but we found no studies testing them for it.
Can I sleep in a scleral lens to protect my eye overnight?
Not unless your eye doctor specifically tells you to. Scleral lenses are normally removed before sleep. Overnight protection for recurrent erosion usually comes from an ointment, and sometimes from a soft bandage lens your doctor places and monitors.
Could taking a scleral lens out cause an erosion?
We haven't found research on this in recurrent erosion. Handling any lens near a fragile cornea carries some risk, and in one small study of children, putting a scleral lens in caused a corneal scratch. If your surface tears easily, ask your fitter how to remove the lens with as little contact with the cornea as possible.
When might a scleral lens make sense for me?
A fitter and cornea specialist might consider one if erosions have left your cornea scarred or irregular so that glasses don't give clear vision, or if you have another surface disease that a scleral lens is used for. It's a decision to make with them, usually after standard treatments have been tried.
Will recurrent corneal erosion go away on its own?
Many cases settle with conservative treatment, but some keep coming back. Your eye doctor can tell you whether a procedure that helps the surface reattach is worth considering in your case.
Do people with recurrent erosion say scleral lenses help?
Experiences are mixed. Some long-time sufferers report far fewer erosions while wearing scleral lenses alongside their other treatments, while others found the handling, care, and cost outweighed the benefit. Because research on this use is lacking, it's a decision to make with your cornea specialist and fitter.
What should I do if my lens feels stuck?
Stop pulling. Put in a drop or two of artificial tears, wait a minute, and try again gently with the plunger on the lower part of the lens rather than the center. If it still won't come out after a few gentle tries, call your eye doctor rather than forcing it.
My eye was red and sore after a long day of wear. Could that be an erosion?
It could be, or it could be from building up wear time too quickly. If the eye feels scratched, painful, watery, or light sensitive, leave the lens out and call your eye doctor today. Don't put the lens back in until they have checked your eye.
My cornea specialist doesn't recommend scleral lenses for me. Should I push for them?
Ask them to explain why, since the reasons may be specific to your eye. If you still have questions, a second opinion from another cornea specialist or an experienced scleral fitter is reasonable. Weigh that advice above other people's experiences.
