Abstract Details


To study and report corneal changes in keratoconus patients who had undergone highly accelerated corneal collagen crosslinking (KXL)


Vision lasik center, Emory university hospital, Atlanta, Georgia, USA


28 keratoconus patients (38 eyes) had undergone KXL and were followed up at postoperatively 1, 3, 6, 12 month. KXL was done for 2 minutes 40 seconds with UVA 45 mW/cm2 (7.2 J/cm2) and Refraction, Pentacam HR® and RTVue® were measured on each postop visit.


The average age of patient was 33.6 year-old and the ratio of male to female was 4 : 3. K- values of central and peripheral cornea were changed differently; central flatter and peripheral steeper. Thickness of central 6 mm zone cornea had been decreased, especially between inferior 2-5 mm zone. The radius of Best Fit Sphere (BFS) in both anterior and posterior surface was increased. ARTmax was decreased while index D was increased in ectasia enhanced display of Pentacam HR®.


Corneas had changed to refractively better conditions for 1 year after KXL, compared to preoperative states.
