| Summary: |
Purpose: Evaluation of the usefulness of
corneal scanning topography performed with Orbscan for the localization of corneal graft
due to keratoconus.
Material and methods: We examined 33 eyes in 33 individuals (23 men 10
women) during one year 2000 / 2001. Corneal topography was performed with Orbscan
apparatus before the transplantation of the cornea due to the keratoconus. Trepanning
depended of the thickness of peripheral cornea. Visual acuity without correction was
compared with the control group of 33 eyes, after corneal transplantation done due to the
corneal cone between 1998 - 1999, without consideration of scanning topography.
Results: Significant differences in the post-surgical visual acuity in
favor of the examined group in the range from 5/5 to 5/7 and from 5/25 to 5/50 were
observed.
Conclusions: Scanning corneal topography will probably facilitate proper
qualification for the transplantation and better postoperative visual acuity. |
