Main Results:

  • New data on the accuracy, limitations, and comparative performance of topographic devices.
  • Videokeratography reveals corneal shape changes after excimer laser photorefractive keratectomy, radial keratotomy, penetrating keratoplasty, trabeculectomy, and strabismus surgery.
  • Subtle topographic abnormalities from contact lenses identified; early keratoconus detection and genetic insights provided.

Conclusions:

  • Videokeratography is essential for assessing refractive surgery outcomes.
  • The technology aids in managing keratoconus and contact lens-related issues.
  • Computer-assisted topographic devices are valuable for early keratoconus screening in refractive surgery candidates.
