Laser vision correction, eye diseases (ophthalmology), laser vision correction

The intense pace of modern life, a number of computer and daily leisure time in front of the TV screen will inevitably lead the patient to receive an ophthalmologist with complaints of impairment. What advice and recommendations will give a doctor, it is unknown, but advertising promises wonderful healing with laser correction. Is it so?

Laser vision correction — One of the most modern and popular methods for the correction of the anomalies of refractures: myopia, hyperopia and astigmatism. The procedure is aimed at improving the quality of life of people with ophthalmological problems. Many resort to correction today, using various paths and methods for this.

Some gladly eat forest blueberries in huge quantities and quite satisfied with the result. Others take multivitamin complexes and biologically active additives, noting a positive effect. Third consider glasses or lenses in an ideal way to solve all problems.

But there is, of course, those who are inclined to improve the quality of life by surgical intervention. They note a significant improvement in the optical properties of the eye after surgery.

A bit of history

Ophthalmologists have been engaged in questions to improving the quality of view. But only in the second half of the 20th century, with the development of science and high technology, interest in this problem increased. Significant contribution to the study of the issue was made by ophthalmologists of the whole world, among them Colombian José Barraker, Russian Svyatoslav Fedorov, American Stephen Trokel.

For the first time in the world, the operation of excimerlaser keratomy was fulfilled in Novosibirsk in 1988 under the leadership of. Rzhev and B. Chebotareva. Today it is simply impossible to underestimate the contribution of Soviet and Russian ophthalmologists to the study of laser technology correction technologies.

Advantages of modern methods

One of the most important advantages of modern laser correction techniques — high-tech equipment that allows you to seek the perfect corneal surface. The exceptional accuracy of the correction is expressed that after surgery, a person clearly sees it clearly and contrasting items that are at various distances from the eyes. High quality restored vision manifests itself and the possibility of excellent evening and night vision, minimal rainbow circles and glare around a bright light source. There is another advantage of laser vision correction: this is the possibility of correction and adjustment of errors during operational interference on other excimer lasers or in the case of non-complicated complications.

Methods of FRK, Lasik and Superlasik

Photorefractive keratocorrection (FRK) — This is a time-tested and results method of laser vision correction. The essence of the procedure is that during the operation, the doctor forms a new surface of the cornea using an excimer laser. This highly accurate ophthalmological intervention is performed quite rarely, except in the case of a thin cornea.

In Lasik technology (the name was formed from the first letters of English writing Laser-Assisted in situ keratomileusis), microsurgical effects and receptions of excimerlaser technology are applied. The use of a special device, microcratic, allows you to affect the inner layers of the cornea. At the same time, it is not affected by the upper layers, as it happens when the FRK is, but the average where the evaporation of optically distorted areas of the corneal tissue with a laser beam occurs. As a result, the cornea acquires optical individual parameters and vision is restored.

The most secure and popular operation today — Superlasik, with which you can increase the sharpness of the vision of those who have previously been contraindicated with laser vision correction. The cornea is also formed according to individual parameters.

It is worth noting that the age limitariness in both eyes is treated today using the PRESBY-LASIK technique. After the operation, the patient is equally well fixed on the close objects with both eyes and gets a clear image of remote objects.

Contraindications

Laser vision correction Lasik method — The highest-tech ophthalmological operation of restoring vision using a computer program and the necessary prior diagnostic survey. But she has not only indications, but also contraindications.

Unfortunately, there is a whole category of patients who like a simple procedure is contraindicated. A number of severe chronic and inflammatory diseases will not allow laser vision correction. Significant danger is a sugar diabetes in severe, diseases of the visual system, such as keratoconus with thinning of the cornea, cataract, glaucoma, progressive myopia or previously operated retinal detachment, dystrophy, corneal degeneration, changes from the eye bottom and other eye problems.

Remote consequences and complications

Taking into account the degree of risk, it is unlikely that a specialist will recommend an operation if there is no special testimony for it. As with any operational intervention, during laser correction of vision, the Lasik method is also possible complications and remote consequences, both during the operation itself and in an early or later reducing stage. It can be keratoconus, dry keratoconjunctivitis, vision oscillations, a foreign body or a fluid under the cornea, the destruction of the vitreous body, erosion of epithelial tissue and other.

Laser vision correction covered myths as a web. Looking at the rich and famous, who just like we, wearing glasses, we begin to doubt: is it worth it? You have to make a choice: image or good vision, beautiful frame or operation fee. Why the richest man of the planet Bill Gates wears glasses? I want to think that he is able to pay this procedure. The solution depends on the individual preferences and general health status.
