Studies suggest that flap complications occur in from 0.3 to 5.7 percent the LASIK procedures, according to the April 2006 issue of American journal of Ophthalmology. In a research of 3,009 consecutive LASIK surgeries performed respectable 2002 with July 2009 using a femtosecond laser for flap creation, flap complications emerged in fewer 보다 one-half the 1 percent (0.37 percent) of this procedures, and also all complications were successfully managed within the exact same surgical session.

Some inflammation of the cornea after ~ LASIK surgical treatment is normal. Yet if that is uncontrolled, together in DLK, it deserve to interfere with healing and cause vision loss. If DLK occurs, it commonly responds to therapies such together antibiotics and also topical steroids.
