Purpose:
To study the effect of Riboflavin and ultraviolet A induced collagen cross linking (CXL) in post-LASIK ectasia
Setting:
A private high volume LASIK clinic in Kuwait
Methods:
Twenty eyes of seventeen patients undergoing collagen cross-linking, measurements at 1, 3,6, 12 and 24 months after corneal cross linking were: Best corrected visual acuity (BCVA), slit lamp examination, the Oculyzer for detecting K readings, corneal thickness, and anterior and posterior elevations maps. RESULTS There was significant improvement of BCVA and K readings at two years postoperatively. The mean BCVA improved from 0.4 ± 0.25 to 0.64 ± 0.21(P<0.05). Mean flattest( K1) and steepest (K 2) readings changed from 47.52 ± 3.51 and 50.1 ± 4.51 to 46.08 ± 4.47 and 49.11 ± 5.64 respectively (P=0.015, 0.013).The Mean Apical and thinnest corneal thickness changed from 451.2 ± 21.62, and 432 ± 36.21to 433.± 48.28 and 411 ± 44.84 respectively (P=0.011, < 0.001). The maximum height of anterior and posterior float changed from 38.51 ± 17.61and 60.42 ± 21.61 to 31.45 ± 19.49 and 51.71 ± 21.81, respectively.
Conclusions:
Collagen cross-linking can arrest and partially reverse the progression of ectasia in patients with post LASIK ectasia.
