Photoastigmatic Refractive Keratectomy in Myopes
Journal of Refractive Surgery, 2000ABSTRACT PURPOSE: Photoastigmatic refractive keratectomy (PARK) was studied in a multi-center clinical trial. The Nidek EC-5000 excimer laser was evaluated for its effect on refraction, visual acuity, and safety measures as part of a U.S. Food and Drug Administration (FDA) regulated study. METHODS: Eight U.S. centers enrolled adults

Photoastigmatic Refractive Keratectomy for Compound Myopic Astigmatism with a Nidek Laser
Journal of Refractive Surgery, 1997ABSTRACT BACKGROUND: With advances in the delivery of excimer laser energy to the cornea, spherocylindrical ablations are now possible. The refractive and visual outcome of eyes undergoing photoastigmatic refractive keratectomy with a minimum of 12 months follow-up are presented.

Outcome of corneal and laser astigmatic axis alignment in photoastigmatic refractive keratectomy
Journal of Cataract and Refractive Surgery, 2000To compare the refractive results of laser astigmatic treatment in eyes in which the astigmatic axes of the eye and laser are aligned by limbal marking at the 6 o'clock position and in eyes that are not marked.University Hospital and Clinics, Madison, Wisconsin, USA.This retrospective study comprised 143 eyes that had photoastigmatic refractive ...

ABSTRACT PURPOSE: To compare the efficacy and safety of laser in situ keratomileusis (LASIK) and photoastigmatic refractive keratectomy (PARK) to treat moderate and higher myopic astigmatism. METHODS: A retrospective nonrandomized study of 78 eyes with myopic astigmatism (range, 2.00 to 6.00 D) was undertaken. Thirty-eight eyes were

Photoastigmatic refractive keratectomy in 168 eyes: Six-month results
Journal of Cataract and Refractive Surgery, 1994Using a 193 nm excimer laser, we performed elliptical astigmatic and spherical corneal ablation on 168 eyes with compound myopic astigmatism and analyzed the three- and six-month postoperative results. Mean preoperative astigmatism was 1.51 +/- 0.81 diopters (D).
