What causes myopia?
When the eyeball is too long.
With myopia, objects at close distance appear clearly, and on the other hand at far distance they appear blurred. The reason for this is that incident light rays are focussed not directly on the surface of the retina but before it since the eye-ball is too long. The longer the eye-ball the weaker the eye sight - that is the person is short-sighted and distant objects appear blurred.

Treatments for a life without glasses
For the correction of myopia there are surgical possibilities within the cornea (cornea resp. Laser treatment) and the eye lens ( lens treatment):
With the laser treatment, tissue of the cornea is eliminated in order to compensate the length of the eye-ball. This requires a certain thickness and stability of the cornea.
With the lens treatments, an artificial lens is inserted in order to alter the refraction behaviour. Lens treatments allow the compensation of very substantial visual defects as there is no limitation regarding the removing of corneal tissue.
Depending on the kind of visual defect, there are several treatment possibilities:
Which treatment is suitable for me?
Eyes differ. Depending on the state of the eye and the type of myopia there are different methods. Today in 80% of laser treatments the SMILE method is applied. It is the eye laser method of the new generation compared to the classic LASIK or even Femto- LASIK methods it works without a flap.
