Mitomycin C in Photorefractive Keratectomy

Journal of Refractive Surgery, 2009
Purpose: To evaluate the outcome of primary or retreatment photorefractive keratectomy (PRK) or photo-therapeutic keratectomy (PTK) with mitomycin C (MMC) 0.02% applied prophylactically intraoperatively for the prevention of haze and regression in cases of significant haze and regression after primary PRK, due to previous ...

Induced astigmatismafter photorefractive keratectomy

Journal of Cataract and Refractive Surgery, 1999
To retrospectively analyze a group of patients to determine whether their induced astigmatism was caused by asymmetry in the laser beam, asymmetry in ablation rates, or wound healing in different corneal meridians.Single-center physician office.In this study, 146 eyes of 116 patients who had photorefractive keratectomy (PRK) for myopia with the Apex ...

Photorefractive Keratectomy in 472 Eyes

Journal of Refractive Surgery, 1993
ABSTRACT Between July 1990 and July 1992, 472 eyes were treated with photorefractive keratectomy (PRK) using the ExciMed UV200 193-nanometer excimer laser (Summit Technology, Inc. Watham, Mass). The sphere equivalent refractions ranged between - 1.25 and - 9.60 D, with less than 1 .25 D of astigmatism. Eyes with refractive error up to -6.00 D

Photorefractive Keratectomy for Astigmatism

Archives of Ophthalmology, 1991
Excimer laser photorefractive keratectomy, developed to perform radially symmetric ablations to correct myopic or hyperopic refractive errors, was used to perform toric ablations designed to correct cylindrical errors. An expanding slit was used to flatten the cornea in the steep meridian.

Excimer Laser Photorefractive Keratectomy for Hyperopia

Ophthalmic Surgery, Lasers and Imaging Retina, 2001
* 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 ...

[Photorefractive keratectomy in hypermetropia].

Journal francais d'ophtalmologie, 1999
The purpose of this study was to assess the predictability and efficiency of the photorefractive keratectomy in hyperopia.Thinty-eight eyes of 21 patients with the mean age of 34.6 were included. The eyes were divided into 3 groups according to their hyperopia. Group 1: 14 eyes with hyperopia greater than +7.25 D. Group 2: 13 eyes had hyperopia ranging
