Study: Accelerated cross-linking procedure safe
NEW ORLEANS — One-year results of accelerated corneal cross-linking in keratoconus patients determined the procedure to be safe, according to a poster presentation here at the American Academy of Ophthalmology meeting.
“Accelerated corneal cross-linking appears to be a safe procedure, according to the [keratometry] values decreasing, no harmful damage to the endothelium and increases in visual acuity,” the study authors said in the poster.
The prospective, cross-sectional comparative study included 50 patients between the ages of 10 years and 40 years who underwent accelerated cross-linking treatment performed with the KXL system (Avedro) in January 2012. The main outcome measures were best corrected visual acuity, maximum keratometry (Kmax) values and endothelial cell count, the poster said.
Preoperative and 12-month postoperative Kmax values were 57.6 and 56.8, respectively. BCVA was 0.49 logMAR preoperatively and 0.48 logMAR postoperatively, and endothelial cell counts were 2,404.4 cells/mm2 and 2,403.5 cells/mm2, respectively.
