[Special indications for photorefractive (PRK) and phototherapeutic (PTK) excimer laser keratotomies. A presentation of 5 cases].
Five patients with specific indications for photorefractive and phototherapeutic keratectomy (PRK and PTK) by excimer laser at 193 nm were treated successfully: they had presented with epithelial dystrophy of the cornea, amyloid, von Szilly's scleroperikartitis, myopia after cataract extraction and before secondary implantation of an intraocular lens in the other eye, and myopia. In all cases it was possible to avoid extensive surgical procedures such as lamellar keratoplasty or intraocular lens exchange. There were no recurrences in the patients with superficial corneal diseases, and the patients who had undergone PRK were within 0.25 Dpt of the target acuity. The follow-up was between 8 months and 1 year.
