Recurrent Cornea Erosions

Recurrent cornea erosions (RCE) is an eye condition where the outermost layer of the eye, known as the corneal epithelium, repeatedly breaks down or fails to stay properly attached to the underlying layers of the cornea. This can cause sudden episodes of eye pain, usually upon waking, as the eyelid sticks to the healing surface of the cornea during sleep and disrupts it when the eye opens.

Common symptoms of recurrent cornea erosions include sharp eye pain, a gritty or foreign body sensation, watering of the eyes, blurred vision, and sensitivity to light. These episodes often occur in the early morning and can vary in severity from mild discomfort to significant pain and vision disturbance. While symptoms may resolve between episodes, the condition can recur unpredictably if not properly managed.

The most common cause of RCE is a previous eye injury, such as a scratch or abrasion, which disrupts the normal healing of the corneal surface. It can also be linked to underlying conditions like corneal dystrophies, which affects how the corneal surface adheres to its underlying layers. Dry eyes and certain types of eye surgeries may also increase the risk of developing this condition.

Treatment for recurrent cornea erosions depends on the severity of the symptoms. In milder cases, lubricating eye drops or ointments may help. In cases where conservative treatments do not work, procedures such as anterior stromal puncture or laser treatment (Phototherapeutic Keratectomy) may be recommended to help the corneal layers bond more securely.

If you experience repeated episodes of eye pain, especially upon waking, it is important to seek prompt evaluation. At our clinic, we offer thorough assessments and tailored treatments to help relieve your symptoms and reduce the risk of recurrence, ensuring your eyes remain comfortable and your vision stays clear.

Phototherapeutic Keratectomy (PTK)

Phototherapeutic Keratectomy (PTK) is an advanced laser procedure that can effectively treat recurrent cornea erosions, especially in cases where other treatments have not provided lasting relief. This technique uses a precise excimer laser to remove the damaged or poorly adherent outer layer of the cornea and smooth out any irregularities on the surface. By reshaping the cornea, PTK encourages stronger and more stable healing, helping to reduce the risk of future erosions.

PTK is typically performed as an outpatient procedure under local anaesthesia, and it is generally well tolerated. After the treatment, a protective contact lens is placed over the eye to aid healing and minimize discomfort. Most patients experience noticeable improvement in their symptoms after the eye has healed, with a significant reduction in the frequency and severity of erosion episodes. At our clinic, we carefully evaluate each patient to determine if PTK is an appropriate and effective treatment option for their condition.
