Femtosecond Laser-Assisted LASIK Flap Complications

J Refract Surg. 2016 Jan;32(1):52-9. doi: 10.3928/1081597X-20151119-01.


Purpose: To discuss intraoperative and postoperative femtosecond laser-assisted LASIK flap complications and their management.

Methods: Review of published literature.

Results: Flap creation is a critical step in LASIK. The femtosecond laser has improved the overall predictability and safety of the lamellar incision, but complications can still occur during or after flap creation. Although many complications (eg, epithelial ingrowth and flap striae) were reduced with the femtosecond laser application, other specific complications have emerged, such as vertical gas breakthrough, opaque bubble layer, and transient light-sensitivity syndrome.

Conclusions: The application of femtosecond laser technology to LASIK flap creation has increased greatly since its introduction. These lasers have improved the safety and predictability of the lamellar incision step. The majority of the femtosecond laser-assisted flap complications can be well managed without significant effects on refractive outcomes.
