incomplete or irregular corneal section (pre-surgical vision is retained);
defect on the surface of the cornea (recovers quickly).
After the surgery:
dry eye syndrome (it is necessary to use artificial tears);
vision disorders in dim and dark conditions (typically passing, rarely persistent);
overcorrection or undercorrection (the surgery can be repeated after three months, within three years after the surgery, repeated surgery is free of charge for the patients who have had the surgery at the clinic Silmalaser);
regression (short-sightedness recurs to some extent, typically within three months; this is more common after the correction of high myopia exceeding -6 dioptres);
decrease in the maximum corrected visual acuity;
in-growth of the cells of the surface of the cornea (epithelium) under the edge of the LASIK flap (requires repeated surgical intervention, but does not cause permanent visual disorders);
infectious inflammation (extremely rare in global practice);
DLK (diffuse lamellar keratitis), i.e. a sterile inflammation of the cornea (rare and generally treated with anti-inflammatory eye drops).
