METHOD OF TREATING POST-LASIK KERATECTASIA

摘要

FIELD: medicine.SUBSTANCE: invention relates to medicine, namely to ophthalmology and can be used for treatment of post-LASIK keratectasia. For this purpose in space under epithelial-stromal corneal flap round recess is made from periphery to optic zone (in central zone of cornea), into which hypotonic riboflavin solution is introduced. When thickness of cornea 400 mcm and more is reached, space is filled with 0.1% riboflavin solution on 20% solution of dextran T 500 until cornea is saturated with riboflavin. After that, ultrasonic irradiation of cornea is carried out with wavelength 365 nm with intensity 3 mW/cmfor 30 min fractionally - 6 cycles 5 each 5 minutes long. During irradiation of cornea with ultrasonic waves riboflavin solution is instilled on cornea each 2-3 minutes, additionally riboflavin solution is introduced into recess under epithelial-stromal corneal flap each 5 minutes for constant support of riboflavin solution volume in intrastromal space.EFFECT: method ensures increase of cornea thickness to required level due to creation of conditions for fast saturation of cornea with riboflavin solution, acceleration of healing process with reduction of risk of postoperative complications development to minimum.1 ex
