title: [Recurrent corneal erosion. Different treatment options with the excimer laser with emphasis on aggressive PTK].
abstract: Recurrent corneal erosions in both traumatic and basal membrane dystrophy-associated conditions seem to show a similar pathogenesis for abnormal adhesion between corneal epithelium and stroma. The purpose of each conservative or surgical treatment is fast healing without any infections or recurrences. This paper compares the different excimer laser treatment options with emphasis on the so-called aggressive PTK. A total of 50 eyes of 50 patients with recurrent corneal erosions after mechanical trauma or with epithelial basement membrane dystrophy were treated with aggressive PTK after the second or third recurrence. Aggressive PTK was performed with an ablation of 10-15 microm. After the mean follow-up time of 41.8 months, a recurrence rate of 6% without a change of visual acuity and a hyperopic shift of +0.74 D were observed. The earliest recurrent erosion showed up after 33 and the latest after 65 months. In comparison to other forms of PTK such as transepithelial or conventional subepithelial PTK, aggressive PTK showed the lowest recurrence rate reported for a long-term follow-up.
