  • Astigmatism - what is it

    Astigmatism is a pathology of eye refraction inwhich violates the sphericity of the cornea, i.e. in different meridians, the different refractive power and image of the object when light rays pass through such a cornea is obtained not as a point, but as a straight line segment. At the same time, a person sees objects distorted, in which some lines are clear, others are blurry. Congenital astigmatism up to 0.5 diopters is found in most people and refers to the "functional", which practically does not affect visual acuity. However, as practice shows, astigmatism is already 1 diopter or more lowers vision and impairs visual comfort. This kind of pathology is detected in approximately 10% of cases among 25% of children with all types of amitropia. Such patients with astigmatism need early vision correction with the help of cylindrical (spherical) glasses. This is the main prevention of amblyopia, strabismus and visual discomfort.

    Astigmatism - objects distorted image, some lines are clear, others are blurred.

    Astigmatism - causes and timing of occurrence

    Astigmatism - Treatment of astigmatismCauses of astigmatism is not fullystudied. In most cases, astigmatism is congenital and inherited character, revealed in childhood. However, the reason can be astigmatism surgery or eye injury. Image objects with astigmatism fuzzy, sometimes blurred, straight lines appear curved. Additionally defects of vision, astigmatism is usually accompanied rapid fatigue the eye, reduced vision, headaches.

    It is important: If there are astigmatism patients in the family - a childmust be examined by an ophthalmologist. Astigmatism is detected only with a full ophthalmological examination. The patient with astigmatism only feels a decrease in visual acuity. For the correct determination of the degree of astigmatism and, especially its axes, a thorough computer examination is necessary. Even small errors in diagnosis can lead to complete intolerance to glasses or lenses, as well as to visual impairment.

    Conservative treatment of astigmatism

    Early diagnosis of astigmatism - Complete ophthalmic examination, including computer research axes of the eyes.

    Proper vision correction - With the help of special glasses with cylindrical lenses or special contact lenses (toric lenses) selected by an ophthalmologist.

    Train myshsch - responsible for the accommodation of the eye (laserstimulation, video-computer vision correction, instillation of drugs, special courses of eye gymnastics) - under the supervision of an ophthalmologist.

    restorative measures - Swimming, neck massage, douches, etc. on the recommendation of an ophthalmologist.

    Good nutrition - Balanced in protein, vitamins and trace elements such as Zn, Mn, Cu, Cr and others.

    Modern methods of correction of astigmatism

    Currently, there are three recognized astigmatism method, namely:

    spectacles - the most common correction methodastigmatism, especially in childhood. Astigmatism uses glasses with special cylindrical lenses - positive or negative - depending on the type of astigmatism. For all its merits, glasses give their owner a lot of inconvenience - they constantly get dirty, fog, crawl and fall, interfere with sports and any other active physical activity. Glasses do not provide 100% vision correction. Glasses significantly limit lateral vision, violate the stereoscopic effect and spatial perception, which is especially important for drivers. In the event of an accident or falling, broken glass lenses can cause serious injury. In addition, improperly selected glasses can cause permanent eye strain and the progression of astigmatism. Nevertheless, glasses today remain the easiest, cheapest and safest method for correcting astigmatism.

    Contact lenses - contact lenses are used for correctionastigmatism, a small degree (up to 3 diopters). With astigmatism, special toric lenses are used, which the ophthalmologist must choose. Toric lenses are characterized by all the limitations and inconveniences, as well as other types of contact lenses.

    Laser correction of astigmatism - for adults (over 18 years old) withmodern ophthalmology offers the most progressive correction method - laser correction of astigmatism in a stable form of astigmatism. The best laser vision correction technology for astigmatism today is LASIK - an operation that guarantees a patient with astigmatism normal vision, without any restrictions.

    Prevention of astigmatism

    light mode - Visual load only in good light, with the top light table lamp 60-100 W, use fluorescent lights.

    Mode of visual and physical activities - It is recommended to alternate visual stress to the active, moving the rest.

    Gymnastics for the eyes - 20-30 minute sessions are recommended exercises for the eyes.
