Health Problems

Glasses, lens, implant, eye doctor explains what lack of vision helps best

Around 40 million Germans suffer from a refractive error. The most frequently-sightedness, presbyopia or night blindness are short. Eye doctor Christoph Eckert explained for each Problem, the appropriate treatment option.

1. Short-sightedness

Short-sightedness is anything other than a symptom of old age: especially in children and young people this eyes takes disease dramatically, as eye doctors warn, all over the world insistently. In many countries In Asia, 90 percent of all young people already suffering from myopia. Even in the Western world, every second in this age group has problems with the Sharp in the distance.

Causes of myopia, the technical term, are mostly the skin too long-grown eyeball or a too strong refractive power of cornea and lens of the eye. As a result, the focal point of incidence of the light rays in front of the retina, and not, as in the case of normal-sighted eyes, on the retina center (macula) is.

About the expert

Christoph Eckert is a eye physician and surgeon. In addition, he is the founder and medical Director of 24 eye care centres in Baden-Württemberg and Bavaria.

The result is that, Without vision, have Affected difficulties, to see distant objects in focus. There are significant visual impairments threaten. Along with genetics, the prevalence in Asian countries with very high education requirements and an extremely long learning and homework times, seem to See frequent close-up (such as at a daily PC – screen work), and to favor to little to bright daylight (artificial light) this eye disease.

What transparency will do for short?

Thanks to glasses or contact lenses short can sightedness very well today correct. In particular, in the case of a deficiency of up to approximately -10 dpt Femto-Lasik is a safe and reliable treatment option. The outpatient procedure is for the patient is hardly or not noticeable, and only takes a few minutes. Since very little tissue is removed, there is usually a faster healing process. The risk of infections and cut complications is in the parts per thousand range.

In the case of high diopter values of up to -18 d, the Implantation of a intra to constitute the eyepiece lens (such as by the ICL method) an Alternative to laser eye. The lens is implanted through a three-Millimeter small Opening at the edge of the cornea, gently in the eye (behind the iris). There it unfolds.

In contrast to glasses or contact lenses do not sit in front of these lenses, but in the eye – what ultimately ensures a higher visual acuity. What transparency protects against short? Instead of staring at the screen, please, more time outside in bright sunlight. Important regular checkups at the eye doctor, as there is an increased risk of a retinal detachment.

2. Presbyopia

A normal-sighted eye, the incidence of breaks of light beams on the cornea (cornea) and the lens and focuses it on the retina center (macula). In the case of far-sightedness, hyperopia called, can represent the eye items skin only behind the retina sharp. The reason for this would be a short-grown eye is, in most cases. As a result, the far-sighted see, if at all, only in the distance.

Already a mm less eye leads length than the usual 24 mm to a Farsightedness 3 diopters. Close work without reading the help is virtually impossible.

As with most refractive errors, the complaints also far-sightedness with onward age. With roughly 50 lenses age harden due to without glasses is no longer available. It comes to the so-called presbyopia, the most common visual disturbances in advanced years.

What sightedness to do with age?

Here Reading help and varifocals, or as a permanent Alternative, the implantable multi-focal lenses: Once used, enable this permanently sharp See – in the vicinity, as well as in the distance. To achieve this, replaces the natural lens by an artificial lens.

For the Implantation of a tiny cut of the skin at the horn edge (the closes to the intervention itself). Through this Mini-Opening, the artificial lens is injected to the desired location, where it then unfolds. Close follow-up after treatment are important, to be able to as early as possible rare complications of lens implantation how to detect and remedy. To infections, or ocular pressure fluctuations.

3. Night blindness

One of the most common refractive errors, the rod density. This is usually the result of an inherited astigmatism. As a result, the on the retina incoming rays of light, incorrectly mapped, and it comes to blurred vision or distortion. In General, this Problem can be, thanks to a pair of glasses with special lenses or contact lenses fast fix.

Especially people in the second half of life often have trouble Seeing in the dark, especially when there is a change from the bright in the dark area. However, this is usually completely normal. Of night blindness, the doctor speaks, when someone in the dark detects very little or nothing at all, or only blurry.

Cause malfunctions or a failure of the swab, so the for the See at dusk, competent sensory cells in the retina. In most cases, night blindness is congenital. But also a strong Vitamin A deficiency, sugar disease or liver damage can be causes.

What blindness do at night?

Therefore, a (eye)doctor’s clarification – as with any visual impairment. The complaints are genetically determined, so no therapy helps. And also the glasses result in generally nothing. Vitamin A deficiency is the (very rare) cause, change of Diet, or, where appropriate, the electronic network can help the skin implants. In the case of Diabetes, a laser treatment may effect an improvement.
