Effect of an elliptical optical zone on outcome of photoastigmatic refractive keratectomy.

Journal of refractive surgery (Thorofare, N.J. : 1995), 1999
This study presents the effect of an elliptical optical zone on the accuracy of correction of astigmatism in patients undergoing photorefractive astigmatic keratectomy (PARK) for myopic astigmatism.We reviewed a consecutive case series of 102 eyes that underwent PARK with a Nidek EC-5000 excimer laser by a single surgeon.

Excimer laser photoastigmatic refractive keratectomy: eighteen-month follow-up.

Ophthalmology, 1998
To study the efficacy of photoastigmatic refractive keratectomy (PARK) by the MEL 60 (Aesculap-Meditec, Jana, Germany) scanning excimer laser for the treatment of myopic astigmatism, with follow-up of 18 months.One hundred and twenty-eight eyes of 102 patients with different degrees of myopic astigmatism were treated by PARK and followed prospectively ...

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 for low, moderate, and high astigmatism using a broad beam excimer laser: evaluataion according to new international criteria].

Klinische Monatsblatter fur Augenheilkunde, 2000
Photorefractive keratectomy (PRK) is an accepted procedure to correct myopia in Germany. The purpose of this study was to evaluate photoastigmatic refractive keratectomy (PARK) for myopic astigmatism.PARK using the VISX 20/20 excimer laser was performed in 50 eyes of 36 patients (25 female, 16 male) aged 22 to 68 years (mean 38 +/- 10 years) in the ...

[A prospective clinical study of correction of myopic astigmatism by combined treatment with PRK and T-incision and photoastigmatic refractive keratectomy. The results after one year].

Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 1999
In contrast to the correction of simple myopia there is no widely accepted technique for the correction of myopic astigmatism. Currently two techniques are available: the photoastigmatic refractive keratectomy (PARK) and the combination of arcuate keratotomies with standard PRK (PRK-T).In two groups, 67 patients underwent a correction of myopic ...
