Eye Surgery. About laser surgery, cataract and glaucoma and what can be done by cataracts?

Cataracts are an eye condition where the vision gradually deteriorates, but where there is likely to be operated successfully as a result. Glaucoma contrast, is a chronic eye disease, which untreated can cause blindness and the eye pressure is the main risk. Treatment of Glaucoma made medically, surgically, but without loss of vision can be restored. Laser treatment is a widely used form of eye surgery each year are used by very many people. LASIK laser surgery is considered safe with minimal side effects. At the same time, however, that one in a hundred gets a worse vision after surgery and will look less clear why risks should always be carefully elucidated before surgery.

Cataract

Cataracts cause the confusion in the eye lens, where vision becomes more or less blurred, and so that glasses are no longer helps. The disease develops over a long period of time, usually several years, whereby the vision gradually deteriorates, and there may also be visual disturbances. Cataracts may be congenital and otherwise in all ages, but is much more common in people over 65 years. It appears often in both eyes, but typically months to years of time lag in the development of the two eyes. Only option for treatment is surgery. Has pronounced cataract in one eye and only slight cataract in the other, it would be a good idea to undergo surgery in the worse eye and get a good view of this, within sight of the other eye becomes too ill to everyday needs. This is a very safe operation, where most will very quickly be able to see, perhaps without eyeglasses. In the western world are operated each year many thousands of cataract and only 2-3 percent of them have significant visual discomfort after surgery.

Symptoms of cataracts

Almost all degrees of altered vision and visual impairment experienced by patients with cataracts. When the lens becomes harder, you can become myopic and find that you can read without glasses or if you previously had a long vision, being able to watch TV without glasses. As the haze in the lens increases, will nevertheless experience reduced vision in both reading and TV. Many are also bothered by the glare of sunlight and car headlights at night. Some experience double vision, even when you close one eye, or letters, in both books as on TV, seen with double contour. There is currently no prevention or medical treatment, so surgery is the only treatment option. Chance to get to look good after a cataract surgery is usually not worse by waiting. One must therefore operate when there is a reasonable relationship between the genes you have in everyday life of the cataracts and the risks related to surgery.

Cataract surgery

The objective is to remove the cloudy lens and replace it with a clear plastic lens. Within corneal refractive surgery is measured and the eye length, the latter with a special ultrasound equipment, so that the strength of the plastic lens can be calculated. The operation itself takes place under local anesthetic and takes about ½ hour. Through a small opening of 3-4 mm on the transition between the white sclera and clear cornea, the doctor may keep its instruments into the eye. Most patients can see fairly well in the first days after surgery, while others will regain sight in a few weeks. One must usually dripping eyes 1 to 3 times a day the first few weeks. Eye examining doctor are generally several times a patient within the first month, and may at the final check on the strength of the new eyeglass, which in most cases, is necessary in order to regain its normal vision. - click rate for ophthalmic surgery >>

Glaucoma

Glaucoma is a chronic eye disease, which untreated can cause blindness when eye pressure is the major risk either by being elevated or at the optic nerve can not tolerate an otherwise normal eye pressure. Glaucoma is most often age related, but the disease can be inherited, occur in adolescence, due to general diseases such as diabetes or eye diseases such as iris inflammation. Treatment of glaucoma is about to lower eye pressure and can be done medically, surgically. Medical treatment is usually first choice and is dripping with eye drops that lower eye pressure. The treatment is for the open-angled type of glaucoma lifelong, while the angled type of closure, in many cases can be cured by laser. Loss of vision due to indulging optic nerve fibers can not be recovered. It is therefore important that the disease is detected and treated as early as possible. Many, many thousands of persons are annually diagnosed with glaucoma. Several studies indicate that almost as many may suffer from the disease without knowing it. One should therefore be examined by an ophthalmologist if you suspect that you are developing glaucoma.

Symptoms of glaucoma

Progressive visual field defects is the main symptom of glaucoma. The process is insidious, as it often does not perceive minor defects in the visual field because the brain "fills" the defective vision, with the believe it to be. Only late in the process becomes visual field defects are so pronounced that they are discovered either by ignoring even larger objects to the side or by the more central parts of the vision is affected to a degree so you can not watch TV or read a newspaper. In the late phase can appear "tunnel vision", allowing only a very narrow field of view with very great inconveniences to follow. In the acute form is most severe eye pain, headache, nausea and sudden loss of vision possibly with colored rings around lights. Glaucoma is usually bilateral, but can develop at different speeds in the two eyes. Since the course is often insidious, discovered the disease in many cases only when one eye has suffered a significant loss of vision. It is therefore important to go to the ophthalmologist in suspected glaucoma. Eye physician will measure the eye pressure, either with an apparatus which allows a small air-puffs of the eye or, after instillation of anesthetic drops, or with an apparatus, which just touches the cornea. Eye pressure is usually between 10 and 21 mm of mercury, but you can have glaucoma, although the pressure is normal. When the eye doctor has diagnosed and started treatment, it is important that you follow the recommended controls, which typically takes place every 3 or 6 months.

Treatment of glaucoma

Whatever type of glaucoma, it is about going all out treatment to lower eye pressure, thereby improving the condition of the nerve fibers of the pupil. Treatment of glaucoma is primarily medical, that is, with eye drops, which attempts to reduce eye pressure. In rarer cases, treatment can be supplemented with tablets and acute glaucoma with medications that drink or possibly injected into a vein. If this treatment is not sufficient, and the pressure despite treatment with eye drops are not low enough, it may become feasible to perform surgery that can be done with laser or diamond knife. An operation of glaucoma surgery is a preventive and a curative is not operating. This means that the operation aims to reduce the pressure so that the progressive disease stopped and the vision does not deteriorate further. One can hope that the eye after surgery have a normal pressure and should not have eye medicine, but it may be necessary to adjust treatment after surgery and possibly give some pressure lowering eye drops. Untreated disease can lead to total blindness. In open-angle glaucoma visual field loss can often be stopped in order not to lose more of vision. Treatment of open angle type of glaucoma is lifelong. In narrow-angle glaucoma can regain normal vision, in many cases can be cured with laser if diagnosis is made on time, and treatment begun.
