• Using Astig PLOT TM , the mean surgically induced astigmatism (SIA) was 0.21±0.88D with the axis of 46±22° which suggest that decompression surgery did change the corneal shape and induced incyclotorion of the steepest axis. (arvojournals.org)
  • Ike Ahmed, MD at the University of Toronto, shares his viewpoint on accurate biometric values and a comprehensive analysis of the corneal surface. (topconmedical.com)
  • The type of analysis produced by this map provides Dr. Saland with very fine details regarding the condition of the corneal surface. (salandvision.com)
  • This plate, supported by a handle, contains a series of concentric rings and a hole in its center, allowing the doctor to see the reflected catoptrics image of the corneal surface of a patient located back to the light incidence. (biomedcentral.com)
  • Different types of topography maps can help you better evaluate the eye's anterior surface and fit contact lenses. (clspectrum.com)
  • Important factors when determining the ideal candidate for ortho-k lenses are corneal steepness and eccentricity. (optometricoffice.com)
  • People who wear contact lenses are also at risk for corneal damage from lenses that don't fit properly or are not properly cleaned or worn as directed. (drleaks.com)
  • At G. Dennis Leaks, OD, LTD, in Pahrump, Nevada, our doctors use state-of-the-art corneal topography technology to create detailed maps of your corneas, so you can get the best care for your needs. (drleaks.com)
  • Coverage extends from a minimum ring diameter of 0.25mm to beyond 10mm, which is ideal for detailed assessment of corneal pathologies and accurate contact lens fitting. (shattky.co.nz)
  • The differences between corneal topography measurement was done using the repeated measure analyses. (eyepress.ru)
  • The range of corneal topography measurement (D) in this study was from 32.8D to 46.3D. The mean corneal topography measurement was 40.86±2.57D, 40.65±2.76D and 40.85±2.72D for preoperation, 6 and 12 weeks postoperation respectively. (eyepress.ru)
  • Corneal topography measurement 6 weeks after the operation was significantly different than that before operation (mean difference = 0.210±0.096, p=0.029). (eyepress.ru)
