Resumen
Background: Orthokeratology purpose is to reduce myopia, through morphological corneal changes, induced by the use of hard contact lenses. The development of the new reverse geometry lenses and the corneal topography, have led this controversial practice to its boom in the last years. Case Report: A case of a myopic 18 year old male under orthokeratological treatment is reported. The patient was diagnosed of a punctate epithelial keratitis and a perineural infiltrate of his left eye. In spite of antibiotic therapy, the lesion failed to heal and turned into a corneal ulcer which involved the stroma. The patient recognized to rinse the contact lenses with running water. A corneal scraping and a microbiological examination of contact lenses was carried out, isolating Acanthamoeba. Treatment was established with topical antiobiotics, propamidine isethionate and chlorhexidine, and orally with fluconazole, obtaining the healing of the process. Conclusions: Since the prognosis of this type of keratitis depends on how fast a diagnosis is performed, it is essential, to recognize the initial corneal disturbances occured in this pathology. When using rigid contact lenses for orthokeratology, even a debatable method, all hygienical recommended steps in contact lenses must be followed.
