    Femtosecond laser-enabled approach allows treatment of high astigmatism

    By Cheryl Guttman Krader

    Las Vegas—Femtosecond laser intrastromal arcuate keratotomy (AK) under a corneal flap is feasible and appears to be safe and effective for reducing high astigmatism, according to the early experience of António Limão, MD.

    Speaking at the 2015 meeting of the American Academy of Ophthalmology, Dr. Limão presented outcomes for a series of 10 eyes of 10 patients treated with the novel technique that he said combines the safety of purely intrastromal AK with the effectiveness of classical surface AK.

    “Whereas intrastromal femtosecond laser AK can only be used to treat up to 2 D of astigmatism, intrastromal femtosecond laser AK under a corneal flap could treat higher levels of astigmatism just as traditional arcuate keratotomy can,” said Dr. Limão, IMO, Lisbon, Portugal.
