Excimer laser photorefractive keratectomy for hyperopia.
BACKGROUND AND OBJECTIVE Photorefractive keratectomy (PRK) has been extensively evaluated for the correction of myopia. This study was undertaken to assess the safety, efficacy, and reliability of PRK in the correction of hyperopia. PATIENTS AND METHODS There were 28 eyes with refractions of +1 to +7.75 D treated for hyperopia with the Chiron Technolas 217-C excimer laser. Thorough visual ass...

PURPOSE To determine the efficacy, stability, and predictability of refractive surgery for hyperopia using four different procedures: photorefractive keratectomy (PRK), laser in situ keratomileusis (LASIK), implantation of a phakic intraocular lens (PIOL), and removing the transparent lens with IOL implantation. METHODS We operated on 184 eyes with hyperopia; 56 eyes had less than +2.00 D (lo...
