Abstract Details

Purpose:

To report a case of peripheral necrotizing keratitis after high energy femtosecond laser in situ keratomileusis (LASIK)

Setting:

Anatolia Eye Hospital, Ophthalmology Department, Istanbul, Turkey

Methods:

A 30-year-old female underwent uncomplicated femtosecond LASIK in her right and left eye for myopia. Preoperatively, the manifest refraction was -4.00 -0.50x175 and -5.00 -0.50x10, respectively. Corrected distance visual acuity in both eyes was 20/15. IFS-150 laser was used for flap creation, and laser ablation was performed with Visx Star S4IR excimer laser (Abbott Medical Optics, Inc.).

Results:

On the first post-operative day biomicroscopy of the right eye revealed a 4.5 mm x 1.0 mm area of interface keratitis from 5 o’clock to 7 o’clock, left eye revealed a 5.0 mm x 0.5 mm area of interface keratitis from 5 o’clock to 8 o’clock at the flap edge. Uncorrected distance visual acuity (UCVA) was 20/25 and central cornea was clear in both eyes. Moxifloxacin and prednisolone asetat was prescribed every hour in both eyes. After confocal microscopy, the patient was started to oral prednisone 60 mg per day. One month after surgery, no infiltrates were seen on examination.

Conclusions:

Increased femtosecond laser energy level can cause peripheral keratitis at the flap edge. The most important condition is to distinguish these cases from infection.
