Abstract Details

Purpose:

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

Setting:

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

Methods:

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.

Results:

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®.

Conclusions:

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