PURPOSE: To evaluate the objective and subjective outcome after phototherapeutic keratectomy (PTK) on recurrent corneal erosions (Hamburg protocol).
METHODS: For the standardized PTK according to Hamburg protocol a manual abrasio corneae performed with 20 % alcohol is followed by an excimer ablation depth of ≥15 μm (group1 15 μm; group 2 > 15 μm ablation depth) and 7 mm optical zone. All patients (N = 48) were invited for follow-up examinations and the evaluation of changes concerning subjective symptoms.
RESULTS: A significantly reduced subjective impairment of night vision, significantly less pain and less foreign body sensations (for all p < 0.05) were noted in 48 patients that met the inclusion criteria (26 women, 22 men). In the follow-up period an improvement of corrected distance visual acuities (cdva) from 0.80 to 1.08 (group 1) and from 0.58 to 0.99 (group 2) was demonstrated.
CONCLUSION: PTK (Hamburg Schema) is a safe and effective procedure to reduce subjective symptoms and improve discomfort in recurrent corneal erosion.
