Early Results of Photorefractive Keratectomy for Myopic Astigmatism
Journal of Refractive Surgery, 1996ABSTRACT BACKGROUND: The Technolas Keracor 116 excimer laser has been used to correct myopic astigmatism. The purpose of this study was to evaluate the early results in our patients. METHODS: The Technolas Keracor 116 excimer utilizes a scanning beam to correct myopic astigmatism.

Correction of Myopic Astigmatism With Small Incision Lenticule Extraction
Journal of Refractive Surgery, 2014PURPOSE: To evaluate the outcome after small incision refractive lenticule extraction (SMILE) in patients with myopic astigmatism. METHODS: Seven hundred seventy-five eyes from 403 patients with myopia treated with SMILE for a cylinder of 0.75 diopters (D) or more were identified ...

Photorefractive keratectomy with an ablatable mask for myopic astigmatism.
Journal of refractive surgery (Thorofare, N.J. : 1995), 1999To evaluate efficacy, safety, and stability of photoastigmatic keratectomy (PARK) carried out with a Summit Apex Plus laser using an ablatable mask.Forty-one eyes of 41 patients with myopic astigmatism with follow-up of 12 months were evaluated. Treatment efficacy was compared in groups with high (>6.00 D) versus low (< or =6.00 D) preoperative ...

A Mathematic Model to Correct Myopic Astigmatism
2010 4th International Conference on Bioinformatics and Biomedical Engineering, 2010The corneal surface was modeled as a torus before ablation, and the corneal surface was modeled as a sphere after ablation in the myopic astigmatism eye. So the mathematic model to determine the ablation profile in LASIK or PRK was deduced according the two surfaces . The two different-radii of curvature of the torus along its orthogonal meridians were

Hunan yi ke da xue xue bao = Hunan yike daxue xuebao = Bulletin of Hunan Medical University, 1999The VISX 20/20 excimer laser was used to treat 260 eyes with myopia and myopic astigmatism of 166 patients. All patients were followed up for one year. The diopter of preoperative astigmatism was from -0.25-(- 4.00 D (-1.00 +/- 0.62 D). The diopter was lowered to -0.07 +/- 0.40 D at 6 months postoperatively (P < 0.05) and -0.06 +/- 0.39 D at 12 months ...

Klinische Monatsblatter fur Augenheilkunde, 1993Nine eyes underwent superficial ablation with excimer laser for treatment of compound myopic astigmatism. In eight of the eyes, corneal cylinder was naturally-occurring, and in one eye the astigmatism had developed following retinal detachment surgery. All patients have been followed for 9 months.
