[Femtosecond laser-assisted astigmatic keratotomy]

Abstract

Background: For more than 100 years keratotomy has been in the focus of ophthalmology as a treatment option for correction of astigmatism. Femtosecond laser technology provides a new level of precision, standardization and control as well as completely new options, such as purely intrastromal incisions.

Method: The current literature is summarized with respect to femtosecond laser-assisted astigmatic keratotomy (FSAK) in combination with cataract surgery, where less astigmatic correction is necessary as well as after corneal surgery, such as perforating keratoplasty, where higher astigmatic errors need to be corrected.

Conclusion: The FSAK provides a safe treatment option for both scenarios although larger studies with longer follow-up are needed to improve currently available nomograms.
