“…Исследования последних лет показали, что прогрессивные очки не только возмещают дефицит аккомодационного ответа, но и формируют миопический дефокус в вертикаль-ных меридианах поля зрения [64]. То же следует сказать и о мультифокальных (бифокальных) МКЛ.…”

“…То же следует сказать и о мультифокальных (бифокальных) МКЛ. В отличие от монофокальных очковых и КЛ, сохраняющих или даже усиливающих гиперметропический дефокус практически по всему полю зрения при любом направлении взора [57,[64][65][66][67], а также формирующих в глазах с миопией отрицательную СА [68], мультифокальные линзы любой конструкции, имеющие положительную аддидацию в парацентральной зоне, должны наводить слабомиопический дефокус на соответствующие проекции средней периферии сетчатки [69].…”

“…Для целенаправленной коррекции периферического дефокуса разработаны различные виды очковых линз, призванных обеспечить формирование периферического миопического дефокуса за счет особой конструкции со стабильным центральным преломлением и селективным радиальным прогрессивным изменением рефракции в горизонтальном меридиане линзы от центра к периферии [64,[70][71][72]. В нашей стране они доступны под брендом Perifocal.…”

“…Как показали исследования, очки с перифокальным усилением преломления формируют миопический (или уменьшают гиперметропический) периферический дефокус в глазах с миопией [64,70,75]. В перифокальных очках, особенно при взгляде прямо, почти во всех зонах формируется миопический или в 3-4 раза уменьшается гиперметропический дефокус и возникает положительная CA, в то время как монофокальные очки, напротив, формируют гиперметропический дефокус и отрицательную CA (рис.…”

The article presents a theoretical and clinical justification for optical techniques used for the prevention of myopia. Accommodation, wavefront aberrations, peripheral refraction, and retinal image quality are considered as interrelated factors affecting postnatal refractogenesis. A detailed analysis of myopia correction methods, conditions preceding its development and their impact on the dynamics of refraction and eye growth is given. A strategy of optical correction of myopia was proposed, which includes: 1) constant wearing of defocusing binocular positive spectacle lens or Perifocal-P spectacle lens (in case of exophoria) for children at risk aged 4–7 years; 2) constant alternating weak myopic defocusing in case of myopia from 0.5 to 2.75 D, ortho- or esophoria, positive relative accommodation (PRA), peripheral myopia or emmetropia; progressive addition spectacle lens in case of PRA less than 1.0 D; Perifocal-Msa spectacle lens in the case of a combination of reduced PRA and exophoria; 3) Perifocal-M spectacle lens in case of myopia of any degree with already existing hyperopic peripheral defocus; progressive addition spectacle lens in case of PRA less than 1.0 D in combination with esophoria or Perifocal-Msa spectacle lens in combination with exophoria; 4) contact correction with bifocal soft contact lenses or orthokeratological contact lenses (Ortho-K) in case of refusal from spectacle correction. Ortho-K is preferable with moderate and high myopia; 5) bioptic correction: a combination of monofocal soft contact lenses and Perifocal-M spectacle lens to correct peripheral defocus and residual astigmatism is preferable for myopia over 8.0 D and myopia with astigmatism.

To ensure a reliable assessment of the efficacy of myopia control methods and their comparison, it is important that the studies are carried out according to identical protocols. Purpose. To analyze patient examination protocols used by different authors for assessing the efficacy of myopia control methods, and to evaluate the principles of forming the main (treatment) and control groups. Materials and methods. Domestic and foreign authors research works devoted to the assessment of myopia control methods were analyzed, most of which were randomized controlled studies. Results and Discussion. The authors propose their own protocol for evaluation of the efficacy of myopia control methods that includes methods for evaluating the results, recommended number (frequency) and duration of follow-up, represented as a checklist. Conclusion. The proposed protocol can be used for planning and executing a clinical research.Conflict of interest: the authors are members of the editorial board of the journal and recused themselves from review process and from making decision regarding acceptance of this article.
