The treatment options for post–laser-assisted in situ keratomileusis (LASIK) ectasia include contact lens fitting,1 intracorneal rings,2 collagen cross linking,3 deep anterior lamellar keratoplasty4 and penetrating keratoplasty. We describe a surgical technique for management of post-LASIK ectasia using lamellar corneal surgery.
A 28-year-old woman presented with progressive diminution of vision in her left eye since 4 years. The uncorrected distance visual acuity was 20/40 oculus dexter (OD) and 20/200 oculus sinister (OS), and best contact lens corrected visual acuity (BCLCVA) was 20/40 OD and 20/120 OS. The cornea in the left eye showed ectasia with thinning in the inferior part. She underwent bilateral LASIK 9 years ago. The diameter of the LASIK flap was 8.0 mm in both eyes (table 1). Videokeratographic (VKG) readings were 44.87 at 144 degrees/42.12 at 54 degrees in the right eye and 59.25 at 10 degrees/43.00 at 106 degrees in the left eye.
