Changes in Spherical Aberration after Various Corneal Surface Ablation Techniques
PURPOSE The corneal change induced by refractive procedures influence both the postoperative refractive status and the ocular spherical aberration (SA). We evaluated changes in corneal SA after three types of surface ablation: phototherapeutic keratectomy (PTK), myopic photorefractive keratectomy (PRK), and myopic wavefront-guided laser epithelial keratomileusis (LASEK). METHODS Twenty-six ey...
متن کاملPopulation spherical aberration: associations with ametropia, age, corneal curvature, and image quality
PURPOSE The aim of this analysis was to determine the total ocular wavefront aberration values of a large phakic population of physiologically normal, ametropic eyes, gathered under the same clinical protocol using the same diagnostic wavefront sensor. MATERIALS AND METHODS Studies were conducted at multiple sites in Asia, North America, Europe, and Australia. A Bausch + Lomb Zywave II Wavefr...
متن کاملCorneal Spherical Aberration and Corneal Asphericity after Small Incision Lenticule Extraction and Femtosecond Laser-Assisted LASIK
PURPOSE To investigate corneal spherical aberration and corneal asphericity after small incision lenticule extraction (SMILE) and femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK). METHODS This study enrolled 70 patients having SMILE and 64 subjects receiving FS-LASIK. The preoperative spherical equivalent (SE) was -5.83 ± 1.23 diopters (D) and -6.20 ± 1.52 D, respectively. T...
متن کاملReducing changes in spherical aberration and corneal asphericity in moderate and high myopic LASIK
METHODS: A total of 194 eyes of myopic patients were divided into two groups: moderate myopia (M) (≥ 4 D and < 6 D) and high myopia (H) (> 6 D). One of two possible ablation profiles was used in each group: an optimized wavefront profile (WF) (M-WF: Spherical equivalent (SE) = −4.84 ± 0.56; H-WF: SE = −7.28 ± 0.86) and the F-CAT Q optimized type customized algorithm (FC) (M-FC: SE = −4.93 ± 0.6...
متن کاملIn vitro strehl ratios with spherical, aberration-free, average, and customized spherical aberration-correcting intraocular lenses.
PURPOSE To determine in vitro image qualities of artificial eyes achieved with spherical, aberration-free, average spherical aberration-correcting, and customized spherical aberration-correcting IOLs in centered, decentered, and tilted positions. METHODS The in vitro performance of these IOL models was determined by optical bench measurements. The experimental setup included a laser light sou...
