Simultaneous Correction of Unilateral Rainbow Glare and Residual Astigmatism by Undersurface Flap Photoablation After Femtosecond Laser-Assisted LASIK.

PURPOSE To report and document a case of successful rainbow glare correction using undersurface ablation of the LASIK flap. METHODS A 33-year-old woman was treated bilaterally for myopia using femtosecond laser-assisted LASIK with the FS200 femtosecond laser (Alcon Laboratories, Inc., Fort Worth, TX). Postoperatively, she complained of rainbow glare in her right eye, and presented some residual myopic astigmatism. Six months after the initial LASIK procedure, the right eye flap was lifted and a toric excimer correction was delivered on its stromal side. RESULTS Visual symptoms related to the rainbow glare disappeared immediately after the completion of the procedure and did not reoccur. Uncorrected visual acuity improved by two lines. CONCLUSIONS Rainbow glare following femtosecond laser-assisted LASIK can be successfully corrected by undersurface ablation of the flap.
