BARCELONA – Thin-flap femtosecond laser LASIK seems to have a high safety profile with regard to iatrogenic ectasia, according to a speaker here.

At the meeting of the European Society of Cataract and Refractive Surgeons, Nader Robin, MD, presented a retrospective review of 2,000 eyes treated with 90-µm thin-flap IntraLase femtosecond laser LASIK (Abbott Medical Optics). The follow-up was at 2 and 3 years.

"Only one case of central ectasia was reported 6 months postoperatively. By re-examining the preoperative topography, we found signs of subclinical keratoconus," Dr. Robin said.

However, because post-LASIK ectasia can have a late onset, a longer follow-up is needed to draw more reliable conclusions, he said.
