Myopia – the medical term for nearsightedness – is a refractive error that results in distance objects being blurred, while near objects remain clear. It is one of the most common eye disorders. Myopia usually starts in school-age children and progresses until the age of 20. However, myopia can also develop in older adults due to environmental or pathological/medical changes.
Nearsightedness – and what we can do about it
Would you like to regain your sharp distance vision–without glasses or contacts? We offer different treatment options for the correction of nearsightedness.
The Difference between Normal Vision and Nearsightedness
Good vision requires a sharp image being produced on the retina at the back of the eye. The optical system (cornea, crystalline lens and vitreous body) of a normal eye diverts light rays in a way so they land exactly in focus at the point of best vision on the retina, the so-called macula.
This diversion of light rays is called refraction. The total power of refraction is expressed in diopters (D). The total refraction power is determined on the basis of the different parts of the optical system. When the total refraction is zero diopters, objects will be depicted sharply on the retina.
An elongated eyeball (eye that is too long from front to back) is typically the cause of nearsightedness. Because the eye is longer than it should be, the incoming light rays tend to focus in front of the retina, instead of on it. This causes distant objects to appear blurry.
The degree of nearsightedness determines the distance that a patient can see. A patient with severe myopia may only be able to clearly see objects up to a few centimeters away, while a patient with mild myopia may be able to focus on and clearly see objects a few meters away in the distance. With a correction with glasses/contact lenses or refractive surgery, the refractive power of the eye can be decreased and thereby move the focal point onto the macula for sharp vision.
Which Method is Right for Me?
Prior to a treatment, a thorough examination and consultation will always take place, in order to determine whether or not the patient is suitable for laser eye treatment. Safety and diagnostics are our absolute priority. If the examination reveals that a patient is not suitable for ReLEx smile or LASIK treatment, these patients will be offered another solution to correct their refractive error.

More information about Nearsightedness
Myopia in China
- Youth Generation in China (born post 1980)
- 70 – 80 % incidence of Myopia
- Many high myopes in China (higher then -10 diopters)
- IN EUROPE , THE PREVALENCE OF MYOPIA IS ONLY 30%
- Myopic macula degeneration and cataract are twoleading causes for blindness
- High myopes in particular deserve an individually planned treatment
LASIK – Safety?
- 2012, more than 20 years experience with LASIK
- 2012, over 30 million people have undergone LASIK, making it one of the most common surgeries performed worldwide
- LASIK received FDA approval in USA in 1998
- EuroEyes has longer experience with LASIK in Europe than FDA
- LASIK is approved by NASA & for US Navy pilots
The Facts about Myopia
- Laser Eye treatments (Lasik) is suitable for Myopic Patients < - 8,0 -10,0 dpt
- For High Myopic Patients > -10,0 Dpt.needs special vision correction treatments
- 40+ of age myopic patients need glasses for far and for near
- High Myopic Patients have increase risk of Myopic Macula Degeneration
- Myopic Patients have increase rate of Cataract development
- High Myopic Patients have increase risk of Retinal Detachment and needs annual retinal examinations
Guidelines by KRC
- Level of Myopia less than - 10 dpt.
- Level of Astigmatism less than - 6,0 dpt.
- Level of Hyperopia less than + 3,0 dpt.
- Minimum of age: 18 years
- Minimal thickness of the Cornea preop.: > 500 um
- Minimal thickness of Cornea after LASIK operation: > 320 um
