PTK Laser

PTK Laser for Recurrent Corneal Erosion Syndrome (RCES)

Recurrent corneal erosions occurs when the epithelium (surface layer of the cornea) comes loose from the underlying corneal stroma causing intense eye pain and a watery eye. It may occur after mild eye injuries or in those with an underlying condition known as epithelial basement membrane dystrophy (EBMD) which is a type of corneal dystrophy.

The pain in those with recurrent erosions, termed recurrent corneal erosion syndrome (RCES) can be brief or may last for several hours, is typically on waking at night or in the morning when the corneal epithelium becomes more adherent to the back of the eyelid instead of the corneal stroma.

Treatment of Recurrent Corneal Erosions

The main stay of treatment for recurrent corneal erosion is managing acute exacerbations and then longterm regular lubricants (eg. Thealoz Duo daytime drops and Hycosan Night ointment) to help prevent future recurrences.

Acute flare ups usually respond to intensive lubricant drops and ointment combined with an antibiotic drop to help prevent secondary infection. Sometimes a bandage contact lens or removal (debridement) of the loose corneal epithelium is needed in the acute phase where there is little response to intensive lubricants or the erosion is large.

Where symptoms remain frequent despite intensive topical lubricants or other treatment, then Excimer laser resurfacing (PTK, phototherapeutic keratectomy) may be performed which is a straightforward 10 minute daycare treatment.
