Biomicroscopy, optical coherent tomography (OCT) of cornea. We analyzed 27 eyes of 4200 patients, operated on. Male patients – 54%, female – 46%, aged from 18 to 30 years old. Mild degree of myopia – 8 eyes, average degree – 7 eyes, high degree – 8 eyes, average degree of hypermetropia – 4 eyes.


In the absence of ideal adaptation and flap adhesion (regardless of a kind and depth of ablation, even in cases of low myopia) we revealed fissures, folds, vacuolization in the intrastromal space with the help of OCT. In a day postoperatively (even with an emmetropic refraction and 100% visual acuity right after LASIK) patients could complain of visual impairment (refraction could change from -1.0 to +1.0 D at the onset of intrastromal keratitis). It occured because those micro fissures and folds were filled with fibrin in the intrastromal space. In its turn it decreased corneal transparency and caused visual acuity decrease. All these cases need standard treatment, in special cases - additional sub irrigation of a flap. In our clinic we pay much attention to this problem, that’s why the percentage of intrastromal keratitis is very low (about 0.3 %).


Refractive surgeons shouldn’t forget about special carefulness when carrying out a stage of LASIK operation – flap folding, regardless of an initial method of flap formation and its thickness. Applying a contact lens doesn’t solve this problem. FINANCIAL DISCLOSURE?: No
