FIELD: medicine.
SUBSTANCE: invention relates to medicine, specifically to ophthalmology. Ingrown epithelium under corneal superficial flap is treated after cerato-refraction operations. Patient is exposed to Nd:YAG laser at wave length 1064 nm. Nd:YAG laser pulses of minimum power 0.3-0.4 mJ are applied on the edge of the superficial corneal flap in a point closest to an area of epithelial ingrowth until a steam-gas bubble appears and local detachment above it of the edge of the superficial corneal flap is applied. Then, starting from the point on the surface of the grown epithelium, most remote from the local detachment of the edge of the superficial corneal flap, Nd:YAG-laser pulses of minimum power 0.3-0.4 mJ are applied successively on the entire area of the ingrown epithelium to the first formed steam-gas bubble to form a solid steam-gas bubble on the entire exposure area. After that, the contact operating lens is pressed against the cornea, starting from the point furthest from the local detachment of the edge of the superficial corneal flap, towards the place of local detachment of the flap, which leads to extrusion of the continuous steam-gas bubble and detritus of the Nd:YAG laser-destroyed ingrown epithelial cells, and the surface flap in the place of local detachment adjoins independently.
EFFECT: method enables the laser treatment of the ingrown epithelium under the superficial corneal flap following kerato-refraction surgeries, eliminating a risk of the disease recurrence, preserving the biomechanical properties of the cornea and a previous refractive effect of the ametropia correction.
