METHOD FOR CHOOSING ORTHOKERATOLOGY CONTACT LENSES IN CHILDREN AND ADOLESCENTS WITH MYOPIA Russian patent published in 2015 - IPC A61F9/00 

FIELD: medicine.

SUBSTANCE: prior to and after choosing an orthokeratology contact lens, a conventional diagnostic examination is performed. An adaptation behaviour is assessed at every stage of the examination by performing a confocal corneal microscopy in addition to the conventional diagnostic examination. The chosen orthokeratology contact lenses are placed on the surface of the patient's cornea, kept thereon with following up the next morning, 7 days later, one month later and every 3 months for a year. Active keratocytes are detected and quantified in an anterior corneal stroma according to the confocal corneal microscopy findings. If their rate is more than 10, the cytomorphological changes of the cornea are considered to go beyond the norm that requires a keratoprotective therapy to be included, which is supposed to be followed by replacing or cancelling the orthokeratology contact lens if the adaptation behaviour while wearing this contact lens appeared to be unachieved.

EFFECT: method enables increasing the effectiveness in choosing the orthokeratology contact lens.
