Purpose:
|
To determine the significant changes which occur in the corneal parameters, including pachymetry, after corneal collagen cross linking by means of Scheimpflug imaging
|
|
Methods:
|
Standard CXL procedure was done for 40 eyes diagnosed as progressive keratoconus The following parameters were monitored pre and six months post operatively: uncorrected visual acuity ,best corrected virsual acuity ,refractive spherical equivalent ,keratometry1 and keratometry2 ,apex and thinnest point pachymetries, thinnest point coordinates minimum,maximum ,average.pachymetric progression indices, Max. anterior and posterior elevations. Pentacam imaging was used to monitor the corneal parameters of the study
|
|
Results:
|
Following parameters of the study did not show significant changes after CXL: UCVA: (P= 0.65), BCVA: (P= 0.076), S.E: (P= 0.343), Thinnest point X coordinate: (P=0.545), Thinnest point Y coordinate: (P= 0.144), Max. anterior elevation (P= 0.508) and the following parameters showed significant changes: K1: (P= 0.001), K2: (P= 0.015), Apex pachymerty: (P <0.001), Thinnest point pachymetry: (P <0.001), Max. post. elevation: (P= 0.001) and all (Max., Min., Avg.) pachymetric progression indices: (P <0.001 for all 3)
|
|
Conclusion:
|
After CXL the cornea becomes thin and is so, even 6 months later, when evaluated by Pentacam. Validity of Scheimpflug imaging of the corneas after CXL should be determined in further studies
