purpose : to determine cyclotorsional eye movement between the upright position and the supine position, in iranian patients with high preoperative astigmatism methods : this prospective cross sectional study contains 102 eyes of 59 patients who were candidates for refractive surgery with technolas 217z100 excimer laser system for correction of high astigmatism. wavefront measurements using zyw...
متن کاملCorrelation of higher order aberrations and components of astigmatism in myopic refractive surgery candidates
PURPOSE To evaluate the correlation between refractive, corneal, and residual astigmatism and higher order aberrations (HOA) in refractive surgery candidates. METHODS Three hundred and seventy-five eyes of 188 patients aged 28.2 ± 6.24 years with a predominance of females (62.7%) were enrolled in this study. Refraction, topography (Orbscan IIz, Bausch & Lomb, Rochester, NY, USA), and aberrome...

متن کاملAstigmatism induced by conventional spherical ablation after PRK and LASIK in myopia with astigmatism < 1.00 D
BACKGROUND The purpose of this study was to evaluate surgically-induced astigmatism after spherical ablation in photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis (LASIK) for myopia with astigmatism < 1.00 D. METHODS The charts of patients undergoing spherical PRK or LASIK for the correction of myopia with minimal astigmatism of <1.00 D from 2002 to 2012 at the John A...
