Customized photorefractive keratectomy to correct high ametropia after penetrating keratoplasty: A pilot study.
PURPOSE To evaluate preliminarily the safety and efficacy of customized photorefractive keratectomy (PRK) to correct ametropia and irregular astigmatism after penetrating keratoplasty (PK). METHODS This pilot study included five eyes of five patients with a mean spherical equivalent of -5.1±1.46D (range from -2.75 to -6.50D). In all cases, ametropia and irregular astigmatism was corrected wit...

PURPOSE To evaluate the safety and efficacy of customized transepithelial photorefractive keratectomy (PRK) for the correction of iatrogenic ametropia after penetrating keratoplasty (PKP) or deep lamellar keratoplasty. SETTING Eye Clinic, Department of Neurological and Visual Sciences, University of Verona, Verona, Italy. METHODS This study comprised 9 patients who had irregular astigmatism...
متن کاملTopography-guided (NIDEK customized aspheric treatment zone) photorefractive keratectomy with mitomycin C after penetrating keratoplasty for keratoconus: case report.
PURPOSE To report topography-guided photorefractive keratectomy (PRK) with mitomycin C (MMC) after penetrating keratoplasty for keratoconus. METHODS A 34-year-old woman with irregular astigmatism after penetrating keratoplasty in the right eye underwent PRK. Topography-guided surface ablation using the customized aspheric treatment zone ablation (CATz) was programmed for a 5.00-mm optical zon...
متن کاملManagement of postkeratoplasty ametropia: IntraLASIK after penetrating keratoplasty.
PURPOSE The authors describe a technique of laser in situ keratomileusis (LASIK) for the management of postkeratoplasty ametropia using a femtosecond laser for flap creation. METHODS The first step was the placement of a disposable suction fixation ring to ensure that it was well-centered on the graft. The applanation cone was applied; the border of the flap was adjusted according to the edge...
متن کاملLaser in situ keratomileusis for ametropia after penetrating keratoplasty.
PURPOSE To evaluate the efficacy of excimer laser in situ keratomileusis (LASIK) in the treatment of refractive errors after penetrating keratoplasty. METHODS Eight eyes underwent LASIK after a mean 71 months (SD 60) following the initial penetrating keratoplasty. A full ophthalmic assessment was performed before LASIK and at 1 week, 1, 3, 6, and 12 months after surgery. Mean follow-up was 8....
