[Clinical analysis of complications of LASIK using the WaveLight FS200 femtosecond laser].

OBJECTIVE

To explore the incidence of intraoperative and early postoperative complications associated with the WaveLight FS200 femtosecond laser-assisted flap creation in LASIK surgery.

METHODS

A consecutive series of 400 patients (786 eyes) who underwent LASIK using the WaveLight FS200 femtosecond laser from March 2011 to December 2012 were included in this retrospective study. Intraoperative and early postoperative complications were described and analyzed.

RESULTS

The intraoperative complications included suction loss (two eyes, 0.25%), incomplete flap creation (one eye, 0.13%), severe opaque bubble layers (three eyes, 0.38%), anterior chamber gas bubbles (eight eyes, 1.02%), skip lines (12 eyes, 1.53%), and corneal epithelial defects (eight eyes, 1.02%). The early postoperative complications included canal bleeding (eight eyes, 1.02%), diffuse lamellar keratitis (23 eyes, 2.93%), haze (six eyes, 0.76% ), and flap dislocation (one eye, 0.13% ).

CONCLUSIONS

Intraoperative and early postoperative complications of LASIK using the WaveLight FS200 were relatively mild. All patients could obtain satisfactory clinical results with proper treatment.
