Astigmatism can significantly interfere with the normal functions of daily life and often occurs in combination with nearsightedness or farsightedness. Because of astigmatism, the eyes have so much trouble focusing on objects that they become very fatigued. This fatigue can lead to other pains and side effects. Many people with astigmatism have never experienced clear vision.
Astigmatism is a common eye disorder that causes blurred vision at all distances. In most cases, astigmatism can be treated with an eye laser treatment, and in the case of higher visual disorders, we can offer lens surgery. This makes it possible for us to offer you a life without glasses and contact lenses.
Astigmatism - The Problem in Detail
Good vision requires a sharp image being produced on the retina at the back of the eye. The optical system (cornea, crystalline lens and vitreous body) of a normaleye diverts light rays (what we see) in a way so they land exactly in the focal point, the point of best vision, on the retina – the so-called macula. This diversion of light rays is called refraction. The total power of refraction is expressed in diopters (D). The total refractive power is determined on the basis of the different parts of the optical system. When the total refraction is zero diopters, objects will be depicted sharply on the retina.
Ideally the curvature of the cornea is shaped regularly like the surface of a ball. Astigmatism occurs when the corneal surface is more irregularly shaped, more like that of an egg. Instead of coming to a single point, light focuses at several different points both in front of and behind your retina, causing blurred vision. The light is refracted differently through the different curvatures of the cornea, e.g. vertical light rays are refracted differently than horizontal. This results in a distorted image: A dot may appear as a line. The optical correction of astigmatism changes the refractive power of the optical system, allowing light to focus properly for the first time.
Which Method is Right for Me?
Prior to a treatment, a thorough examination and consultation will always take place, in order to determine whether or not the patient is suitable for laser eye treatment. Safety and diagnostics are our absolute priority. If the examination reveals that a patient is not suitable for LASIK treatment, these patients will be offered another solution to correct their refractive error.
