Patients and methods: Myopic PRK (Photorefractive Keratectomy) has been performed on 116 eyes (myopia of between -3.0 D and -25.5 D) in the eye clinic of Lucerne, since october 1990. 25 patients had both eyes treated, 7 eyes were retreated.
Results: Results are satisfactory for myopia of up to -10 D (-15 D); treatment of the higher myopia is problematic.
Conclusion: Regression was the biggest problem in all patients, being the more pronounced the higher the ablation. Based on this experience recommendations for treatment are given.
