  • The present day art of ttingcorneal contact lenses, generally stated, consists `in selecting a lens made up-of an inner spherical surface (or toric surface) to best t the corneal curves of the eye at the apex o f the cornea and ,then examining -this tit -with iluorescein solution between the lens and theeye.

  • The result of this suggestion is to produce a surface of uncertain rate of change of curvature when these steps are blended Touhy Patent 2,510,438, ygranted June 6, 1950, discloses a corneal contact lens having a radius of curvature on its concave side slightly greater than the radius of curvature of the cornea with an increasing clearance at the marginal areas of the lens.

  • An initial test set of 1,012 eyes, including normal eyes, eyes with abnormal corneal and topographic findings but not keratoconus and eyes with keratoconus having a wide range of severity, was used to determine cut points for the KSS. (arvojournals.org)
  • Corneal pachymetry is the process of measuring the thickness of the cornea. (wikipedia.org)
  • It is used to perform corneal pachymetry prior to refractive surgery, for Keratoconus screening, LRI surgery and is useful in screening for patients suspected of developing glaucoma among other uses. (wikipedia.org)
  • Corneal Pachymetry is essential prior to a refractive surgery procedure for ensuring sufficient corneal thickness to prevent abnormal bulging of the cornea, a side effect known as ectasia. (wikipedia.org)
  • Using this technology the user can capture an ultra-high definition echogram of the cornea, somewhat like a corneal A-scan. (wikipedia.org)
  • Pachymetry using the corneal waveform process allows the user to more accurately measure the corneal thickness, verify the reliability of the measurements that were obtained, superimpose corneal waveforms to monitor changes in a patient's cornea over time, and measure structures within the cornea such as micro bubbles created during femto-second laser flap cuts.

  • Using this technology the user can capture an ultra high definition echogram of cornea, think of it as a corneal A-scan. (wikipedia.org)
