LASIK Complication due to Laser Firing Failure and its Management

A case of an intraoperative Laser in situ keratomileusis (LASIK) complication due to excimer laser firing failure was presented. After cutting the corneal flap, excimer laser treatment was initiated. However, at 34% completion the laser (Technolas((R)) 217z Bausch & Lomb Rochester, NY) stopped firing for no apparent reason. The flap was repositioned over the cornea and the patient was sent to the waiting room. The laser technician was called and he resolved the problem within 20 mins. The same treatment profile was loaded into the laser instrument and 34% of the excimer laser treatment was applied to a piece of paper. Then, the patient was returned to the operating theater and the flap was reopened with a cannula. The remaining (66%) excimer laser treatment was applied in the same session. On the following day the cornea was clear and the uncorrected visual acuity (UCVA) was 20/20. The UCVA increased to 20/16 in the first week and remained at this level at the 6-month follow-up.
