[Use of low-energy laser irradiation in patients with progressive myopia]

A method of infrared laser exposure at a wavelength 1.3 microns for the treatment of progressive myopia has been developed, permitting a contactless trans-scleral irradiation of the ciliary muscle. Laser stimulation was carried out in 117 patients (234 eyes) aged 7 to 16. By the end of the first follow-up year the mean values of the positive part of accommodation increased by 2.0 to 2.5 diopters in patients of all age groups. A reduction of the parameters of ocular function was recorded 6-12 months after laser stimulation, though they remained higher than initially. A repeated curse of therapy helped normalize accommodation reserve parameters again. Prestimulation rheographic coefficient in all the examinees was 2.7 +/- 0.03% on an average, after treatment it was 3.44 +/- 0.02%. Hence, ciliary muscle stimulation by infrared laser helps in the majority of cases stabilize clinical refraction.
