Purpose:

To report the outcomes of laser in situ keratomileusis (LASIK) in patients with previous corneal scarring using optic coherence tomography (OCT) imaging to determine flap depths.

Methods:

The charts of 11 eyes of 9 patients with previous off-visual axis corneal scarring that underwent femtosecond-assisted LASIK using OCT guidance for flap depth determination were retrospectively reviewed at a single private practice institution. The baseline characteristics, intraoperative findings and postoperative outcomes were analyzed.

Results:

All 11 eyes underwent femtosecond laser flap creation without significant intraoperative complications. Uncorrected visual acuity improved postoperatively (p<0.0001) and="" remained="" stable="" at="" 3="" months="" follow-up.="" none="" of="" the="" subjects="" lost="" any="" lines="" of="" best="" spectacle="" corrected="" visual="" acuity="" or="" developed="" any="" flap="" complications="" during="" the="" postoperative="" period.="" and="" remained="" stable="" at="" 3="" months="" follow-up.="" none="" of="" the="" subjects="" lost="" any="" lines="" of="" best="" spectacle="" corrected="" visual="" acuity="" or="" developed="" any="" flap="" complications="" during="" the="" postoperative="">

Conclusions:

The OCT-guided femtosecond laser technique described in this report can provide a safe and effective method to deliver LASIK in the setting of previous corneal scarring. Future investigations are required to further validate the findings in this study.
