Photoastigmatic refractive keratectomy for correction of astigmatism after keratoplasty.

Journal of refractive surgery (Thorofare, N.J. : 1995), 1999
The efficacy and safety of photoastigmatic refractive keratectomy (PARK) to correct astigmatism after keratoplasty was evaluated.PARK was performed using the Nidek EC-5000 excimer laser in 10 eyes of 10 patients (mean age: 49.5 +/- 11.5 years) with astigmatism after keratoplasty.The refractive cylinder decreased from 5.80 to 3.20 D, whereas at 6 months,

Photoastigmatic refractive keratectomy in myopes. Nidek US Investigators Group.

Journal of refractive surgery (Thorofare, N.J. : 1995), 2000
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.Eight U.S. centers enrolled adults with eyes having refractive astigmatism up to 4.

Photoastigmatic Refractive Keratectomy or Laser in situ Keratomileusis for Moderate and High Myopic Astigmatism

Journal of Refractive Surgery, 2000
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
