“…76 A study 77 indicates that toric Ortho-K can reduce corneal astigmatism by 48.1% (from 2.35 D to 1.22 D), whereas spherical Ortho-K resulted in a 10.5% decrease (2.29 D -2.05 D). In moderate-tohigh astigmatism, toric Ortho-K also gave better myopia control effect of 55.6% when compared to spherical Ortho-K. A 10-year follow-up study 78 revealed that the increase in AL was more in younger children with a high baseline myopia and that Ortho-K control stabilises after seven years, although a decelerating effect was reported in AL elongation in the early years. 78 An important feature of Ortho-K is that it can create large optical treatment effect in moderate-to-high myopia unlike other forms of optical treatment.…”

Orthokeratology is also comparable to low-dose atropine in reducing myopia progression.…”

The review was conducted using online search engines including PubMed and Google Scholar. Articles published between 2000 and 2019 were included.Results: For the optical methods of myopia control, under-correction has been found to be largely ineffective. However, a recent study shows that myopic children without correction had slower myopia progression (−0.75 D) than fully corrected children (−1.04 D) indicating a 28% reduction. Evidence from various studies indicates that bifocals and progressive addition lenses are not as effective as soft dual focus contact lenses or extended depth of focus contact lenses. Clinical trials indicate that single vision rigid gas permeable lenses did not slow myopic progression. Peripheral defocus lenses and orthokeratology were found to be approximately 50% effective across studies reviewed. Conclusion:Peripheral defocus lenses and multifocal contact lens designs offer the most effective myopia control. Orthokeratology is equally effective but future designs should consider ways of minimising risks of complications with lens wear. More studies would be needed to better understand how under-corrected myopic eyes tend to progress faster, whereas myopic eyes without correction tend to progress slower. A holistic approach and combination of methods may offer the best form of myopia control in the 21st century considering the increase in near work activities and use of digital devices among the most vulnerable groups.

“…Известно, что миопия формируется в детском возрасте, имеет прогрессирующее течение и в Российской Федерации в структуре заболеваний глаза и его придаточного аппарата у детей уже занимает первое место, составляя 34 % [2]. В связи с этим оправдано широкое использование ортокератологии в офтальмопедиатрической практике как признанного метода стабилизация близорукости и предотвращения перехода в миопическую болезнь [3][4][5][6][7][8][9][10]. С 2013 года ортокорнеальная коррекция (ОК-коррекция) включена в Федеральные клинические рекомендации «Диагностика и лечение близорукости у детей» (Национальный протокол), утвержденные Всероссийской Ассоциацией врачей-офтальмологов [11].…”

Оcular Surface in Long Terms of Ortokeratology Lenses’s Use in Adolescents with Myopia

The purpose: to study to evaluate the effect of ortokeratology lenses (OK-lenses) on the state of the ocular surface, depending on the duration of their wearing by adolescents with myopia. Patients and methods. Under control were 212 patients with myopia aged 12 to 16 years, who used OK-lenses “Paragon CRT100” (USA) for a long time (3–5 years). Examination, in addition to standard ophthalmological methods, included evaluation of complaints using the OSDI questionnaire/scale, Schirmer, Norn tests and biomicroscopy with staining of the cornea with fluorescein before and during wearing OK-lenses. Patients with keratopathy additionally underwent scanning confocal microscopy of the cornea using ConfoSkan-4 (Nidek, Japan); bacteriological examination of scraping from the cornea. Results. Clinical and functional signs of dry eye syndrome (SDE) in patients before and after prolonged use of OK therapy are not diagnosed. In 12 (5.6 %) teenagers with non-standard values of corneal curvature, signs of late epitheliopathy were revealed against the background of the absence of complaints. Patients were divided into 2 subgroups depending on the choice of antimicrobial eye drops in addition to keratoprotectors. The results of treatment in both subgroups were the same, but the use of fluoroquinolones was accompanied by an adverse development of SDE. Conclusion. In general, long-term OK therapy of myopia in adolescents is safe. The compulsory condition is an adequate prescription and observance of the wearing and lens care rules. It does not have a significant adverse effect on the clinical and functional state of the ocular surface, including the cornea. The frequency of late epitheliopathies with long-term (3–5 years) wearing OK lenses is 5.6 %, and the severity of the manifestation is characterized mainly by a mild degree. Patients with extreme corneal curvature are in a high-risk group for the development of late corneal complications during the use of OK therapy. If late epitheliopathies are detected while wearing OK lenses, it is necessary to cancel their use and to prevent the development of infectious keratitis, in addition to keratoprotectors, you can add the modern antimicrobial drug with antiseptic effect, for example, Vitabact, as the original, without a preservative, approved medicine for use in children. The use of fluoroquinolone drugs with virtually aseptic inflammation of the cornea is unjustified.

“…Убедительно показано в эксперименте, что относительный гиперметропический периферический дефокус стимулирует осевое удлинение глаза и миопизацию рефракции, а миопический дефокус, напротив, тормозит рост глаза и усиление рефракции [1][2][3]. В клинике эти факты находят косвенное подтверждение благодаря известному тормозящему прогрессирование близорукости эффекту ортокератологии (ОК) и других оптических средств, наводящих миопический дефокус на периферию сетчатки [4][5][6].…”

The purpose of this study was a comparative assessment of the refraction and the axial length (AL) changes occurring in the operated and unoperated eyes of patients with anisometropic myopia who underwent unilateral excimer laser correction. Material and methods. We observed 13 patients (8 women and 5 men) aged 21 to 53 years (34.2 ± 8.6) with anisometropic myopia (averagely, with spherical equivalent of refraction-3.87 ± 1.77 D in one eye and 0.71 ± 0.71 D in the other), who underwent unilateral LASIK. The observation period was 3-5 years (averagely 3.5 ± 1.1 years). The observation included autorefractometry on a Nidek ARK-530A apparatus, ultrasound biometry on a Nidek US-1800 Echosсan (Japan), and pachymetry on a GALILEI G6 (Ziemer, Switzerland). Results. No significant changes in refraction or axial length were observed either in operated or fellow eyes. Changes in the axial length were controversial: 7 operated and 7 fellow eyes showed an increasing tendency while another 6 operated and 6 fellow eyes showed a decreasing tendency (p > 0.05). Conclusion. The data obtained fail to support the assumption that excimer laser reshaping of the cornea produces an inhibitory effect on the development of myopia.
