Pachymetry measurement is mandatory before intracorneal ring segments implantation and before cross-linking in keratoconic patients. The aim of this study is to measure the effect of ring segments implantation on pachymetry measurements using Orbscan and Pentacam.
Clinique de la Vision, Paris, France
We retrospectively compared preoperative and 1 to 3 months postoperative minimal pachymetry in eyes implanted with 5 or 6 mm Keraring or Ferrara intra corneal ring segments, using Orbscan and Pentacam.
55 keratoconic eyes implanted with 5 or 6 mm intracorneal ring segments between June 2010 and October 2012 were retrospectively included in this study. Using Orbscan, minimal pachymetry measurements significantly increased from 420 +/- 57 microns preoperatively to 435 +/- 54 microns postoperatively. Pentacam minimal pachymetry measurements significantly increased as well from 449 +/- 42 microns preoperatively to 459 +/- 44 microns postoperatively.
