Nearsightedness - myopia

Myopia is the vision disorder characterized by blurred vision in the distance. "Myops" comes from the Greek and means "blinking face".

Improvement of myopia, including regular eye examinations

Nearsightedness is a congenital or acquired defective vision of the eye. People who are nearsighted can usually still see well at close range, while objects in the distance appear blurred. The opposite is true for farsighted people: objects in the distance appear sharp and those in the near distance appear blurred.

In nearsightedness (myopia), two forms of defective vision can be distinguished: The so-called refractive myopia with normal eye length but too much refractive power, and the so-called axial myopia with normal refractive power but too long eye axis. Since myopia increases the risk of retinal detachment and contact lenses can damage the cornea, it is advisable for all those affected to have their eyes checked regularly by an ophthalmologist.

Examples of nearsightedness - myopia

Nearsightedness Without impairment

Myopia is the inability to see distant objects clearly. Affected people see these distant objects blurry, but up close they can see everything sharply and clearly.

Treatment options for myopia

Eyeglass lenses or contact lenses

Nearsightedness can be improved by various methods. Eyeglass lenses or contact lenses compensate for the defective vision.

With various surgical methods, even high-grade myopia can be corrected. The goal is for the patient to see sharply without glasses.

Attention in this case the layers of the eye remain unchanged. Therefore, the annual retinal examination is still recommended.

Surgical correction of myopia

In the surgical therapy procedure, the cornea is permanently flattened with a laser.

The laser procedures are called Photorefractive keratectomy (PRK), LASIK or LASEK.

In the best case, the laser procedure can cure myopia. However, the laser procedure is not suitable for all sufferers.

 

Laser procedures for myopia and hyperopia

There is an almost infinite range of eye laser procedures, which differ from each other to a greater or lesser extent. These can be divided into two main groups: the superficial and the deep procedures. The main difference is in the procedure and the target tissue layer. The most important and current procedures are the following:

Femto-LASIK (Laser In Situ Keratomileusis)

Femto-LASIK is the most frequently performed laser treatment and life-style surgery with the highest human satisfaction. Under local anesthesia, the Femto-LASER is first used to prepare a thin flap (0.1 mm thick) on the surface of the cornea. This takes about 25 seconds. The eye is kept open with an eyelid retractor (you cannot close the eye).....

Trans-PRK (transepithelial photorefractive keratectomy)

In trans-PRK (also called SmartSight), under local anesthesia and after an eyelid retractor holds the eye open, the correction is performed on the surface of the cornea without contact or incision. During this process, the epithelium (the cells of the corneal surface that are constantly regenerating) are also automatically removed by the LASER. Previously, these were removed manually by the surgeon (PRK method). Am...

Artificial lens implants: Correction of higher refractive errors

Apart from LASER treatments, correction of refractive errors is also possible very precisely with the implantation of phakic lenses in the eye, in addition to the patient's own lens (phakic lenses). These treatments have been carried out for 30 years and have been performed several million times. The worldwide trend of implamtation is constantly increasing. Indications:- More severe refractive errors- Also for small corrections when...
