Astigmatism Hypermetropo-Hypermetropic

Hypermetropic-hypermetropic astigmatism is a complex type of astigmatism in which the rays refract normally along one of the axes of the eye, and abnormally along the other.

With AGG, a complex mirror focus occurs, which is never located inside the eyeball, usually located along the axis of rotation of the cornea and shifted towards the pupil. Thus, the retina of the eye remains intact and relatively bright (with correct diagnosis of refraction and selection of glasses or contact lenses, astigmatic children see well, actively develop and successfully adapt to society). This provides a sufficient supply of visual function. AGG can be corrected using glasses with a cylindrical (afocal) lens in the corrected eye and an astigmatic spherical lens in the eye with residual myopia or farsightedness.

Correction of AGG is also performed using astigmatic lenses or a cylinder.

It is important to remember that early recognition and treatment of astigmatism can improve a child's vision and development. In children, even a weakly expressed tone of the accommodative apparatus of the eye contributes to astigmatism. Therefore, if astigatism is detected early, parents need to begin its comprehensive corrective treatment in a timely manner.



An astigmatic eye is an eye that has anatomical changes in the shape or curvature of the cornea or lens. A number of interesting properties are usually attributed to such an eye, which do not make this eye worse, but on the contrary make it unique. Among the eye's features are a variety of aspherical elements to correct images directly into the eye through their ability to come into focus on the retina. However, a change in the shape of the cornea leads to a complete loss of the ability to focus the image. Therefore, the cornea of ​​an astigmatic eye must have the ability to collect and direct the image, changing the direction of gaze. Astigmatists experience a sensation of double image while looking at objects in a focused manner. In this case, an imaginary circle is visible in the field of view (FO), the dimensions of which are proportional to the degree of astigmatism. The eye usually sees most clearly in the center, because the refraction of light is minimal due to the fact that the line of focuses in the eye runs along the radial axis. Treatment of an astigmatic-hyperthorpic eye with optical correction requires an integrated approach with constant monitoring by ophthalmologists for the correctness of treatment and adjustment of glasses if necessary. But it may be necessary to use additional methods to correct such eyes according to the rules of optics: prismatic glasses, heterophoria and others. In fact, astigmatic properties contributed to the formation of stereoscopic vision and various ways of communication between people in ancient times and other features that are also known to other people to this day.
