Abstract

Optical element, which embodiments are united by inventors conception, has central zone with stable distance refraction, which is nonaxis-symmetrical surrounded by ring-like zone of refraction progression (degression), to its outer edge at nasal and temporal sides connected different by area and refraction peripheral zones with stable refraction that is stronger (weaker) than central refaction, and to bottom edge connected zone with addition for near-work, from outer border of ring-like zone between outer borders of connected zones in all directions refraction is monotonically decreasing (increasing). Using of optical elements as spectacles during viewing regulates relation between axial and non-axial refraction value, changes relation between nasal and temporal halves refraction values, changes choroid thickness, increases accommodation, changes spherical aberration sign in the eye, saves and increases binocular vision. Multifactorial permanent synergic influence when using device predicts risk of myopia onset, and, in case of myopia manifestation, stops increasing of axial refraction or decreases refraction or slows myopia progression, in hyperopic subjects, conversely, axial refraction values increases.

Description

DEVICE FOR PROPHYLAXIS AND/OR TREATMENT OF VISUAL REFRACTIVE DISORDERS.
The invention relates to medicine, specifically to ophthalmology, and relates to devices for the prevention and/or treatment of refraction visual impairments.
Invention background.
Refraction visual impairments is most common nosology in eye diseases structure and causes lot of significant complications in the eye or whole visual system disorders.
So, in children of early age high degree farsightedness (hyperopia) is the cause of severe visual complications, such amblyopia and strabismus. In turn, the most prevalent visual disorder in older children and adults is myopia (nearsightedness). Myopia, commonly, developing through progression, which provoke several morphological changes and functional disorders of visual system at all. Complications of myopia are usually leads to visual disabilities, that's why myopia is significant medico-social problem, and it's prophylaxis and progression control is still the most current goal in ophthalmology. Drawbacks of present devices and methods to affect myopia in different cases are: absence of prophylaxis effect, disability to affect different etiopathogenetic factors of myopia progression in same time, side effects when using, contraindications to use, disability to affect myopogenic factors permanently, medical cabinet limitations to use, necessity of anesthesia, low efficiency, high expenses and so on. Creation of devices to control myopia progression with possibility to use it in different age groups, without complications, with high efficiency, permanently affecting on most myopogenic factors, without any limitations and economically affordable is the most important medico-social task.
Recent clinical trials shows that myopia has multi-factorial etiology, and leading factors in visual analyzer are: accommodation weakness(3), hydrodynamics malfunction(4), neuroregulation of biochemical processes from retina to choroid and to sclera disorders caused by relative peripheral hyperopic defocus in myopic eyes(9), mostly revealed in horizontal meridian(l), presence of negative spherical aberrations of the eye(8). Also myopia onset risk is increasing if peripheral ref action profile is not strengthened at nearwork(6), if there is some binocular vision impairments, such as heterophoria of esophoria type, which is predisposing to myopia factor(2). In turn, some trials shows, that refraction become more myopic in nasal half during myopia progression(7). Dynamic trials shows, that relations between nasal and temporal sides refraction values at 30 degrees from fovea is changing during myopia progression(l 1). Also, electrophysiological trials shows, that near periphery neurons more reactive on defocus sign(10).
It is known from literature, that non-axis-symmetric surface optical design spectacles(12), using to correct myopia shows high efficiency to control myopia progression, permanently affecting several myopogenic factors(13).
In daily practice, commonly using optical treatment methods for prophylaxis and prevention of myopia progression, including devices with spectacle lenses for everyday wearing. But, last time trials shows, that known strategies which using traditional spectacle lenses don't affecting several factors of etiopathogenetic mechanisms, in particular in progressive myopia, and has low effect or even negative therapeutic effect in some cases(5). Undoubtedly, appearance of brand new production technology called FreeForm to make spectacle lenses, gives us wide possibilities to realize new inventions using free non-axis-symmetrical shapes of optical surfaces, which are available to consider much more unusual features of myopic refraction, creating by this optical conditions for safe therapeutic influence on different pathogenetic factors of myopia progression. Also, safety and permanent optical influence on eye regulating mechanisms using spectacles with non-axis-symmetrical design of lenses, allows to use it in early age (active refractogenesis period) and effectively fighting against congenital hyperopia, stimulating eye growth.
