Analysis of Corneal Topographic Optical Zone and Decentration after Myopic Refractive Surgery
… axis was shorter(p=0.001). CONCLUSIONS: After refractive surgery using Technolas 217 C Eximer laser with eye tracking system, there was no clinically significant decentration. The greater preoperative spherical equivalent, the more decentered ablation were noted in PRK group. The topographical …

Heme Oxygenase-2 as a novel target to treat inflammation and chronic neuropathic pain associated with corneal injury and surgery
Corneal refractive surgery aims at correcting alteration of the shape of the cornea correlated with myopia, hyperopia and astigmatism. More than 12 million patients have undergone refractive surgery since it was approved (see http://www. laser-eye-surgery statistics.com/). Laser-assisted in situ …

Measuring Corneal Topography Using Wavefront Analysis Technique
Refractive surgery has emphasized the need of accurate and precise methods for measuring the power of the human cornea. Available techniques for measuring corneal topography include keratometry, videokeratoscopy, and scanning slit imaging. A new type of instrument, a corneal topographer based on a …

The effect of aberrations and light scatter on visual performance at photopic and mesopic light levels
… in subjects who had undergone excimer laser refractive surgery. Increased aberrations and scattered light or abnormal processing of visual information in the retina and/or the visual pathway are the main causes of retinal image degradation. The purpose of this study was to further investigate …
