Results of bilateral photorefractive keratectomy

Ophthalmology, 2000
To study the refraction and potential risks of bilateral photorefractive keratectomy for myopia.Retrospective, noncomparative case series.Four hundred eighteen consecutive patients (836 eyes) with myopia from -18 to -0.50 diopters (D) had bilateral simultaneous refractive surgery.Refractive surgery was performed with the Nidek EC-5000 slit-scanning ...

Excimer Photorefractive Keratectomy for Myopia

Ophthalmology, 1993
To study the safety, effectiveness, predictability, and stability of excimer laser photorefractive keratectomy (PRK) in 133 normally sighted eyes.An excimer laser was used with a fluence of 160 mJ/cm2 at a frequency of 5 Hz and an ablation zone of 5.0 mm.

Satisfaction after Photorefractive Keratectomy

Journal of Refractive Surgery, 1998
ABSTRACT PURPOSE: To evaluate patient satisfaction one year after photorefractive keratectomy (PRK) for myopia and myopia astigmatism using the Nidek EC-5000 excimer laser. METHODS: This study assessed the level of satisfaction of 6280 patients who underwent PRK after a minimum follow-up of 1 year.

Photorefractive keratectomy in keratoconus suspects

Journal of Cataract and Refractive Surgery, 1999
To compare the refractive outcome after photorefractive keratectomy (PRK) in keratoconus-suspect patients with that in patients with normal corneal topography.Gimbel Eye Centre, Calgary, Alberta, Canada.In a retrospective study, 3 patients (5 eyes) with unusually shaped corneal topography before surgery were selected as keratoconus suspects.

Photorefractive keratectomy in pediatric patients

Journal of Cataract and Refractive Surgery, 1995
This article reports the results of photorefractive keratectomy in nine patients between 10 and 15 years of age who were treated for the following refractive errors: unilateral myopia, post intraocular lens myopia, and unequal hypermetropia with amblyopia. Visual acuity improved and spectacle correction decreased in all patients.

Photorefractive Keratectomy in Ophthalmic Residents

Journal of Refractive Surgery, 2000
ABSTRACT PURPOSE: To find out how ophthalmologists themselves experience the correction of myopia after photorefractive keratectomy. Visuomotor functions were of special interest. METHODS: Four ophthalmology residents and one medical engineer underwent photorefractive keratectomy for myopia.

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.
