• Refractive Surgery

    Refractive surgery has become, thanks to laser-technology, an alternative in the last twenty years, in addition to glasses and contact lenses.

    Indications for refractive surgery:
    • Large refractive asymmetry
    • Refractive problems that can not be corrected with glasses or contact lenses
    • Recovering from injuries
    • Specific activities at work and during leisure time (sports)

    Most common techniques of refractive surgery:
    • Laser surgery with the excimer laser
    • Implantation of an artificial lens in the eye with or without removal of the natural lens
    • Implantation of acrylic plates or rings into the cornea

  • Possibilities and limitations of refractive surgery

    In myopia up to 8 diopters there are good prospects for a satisfactory correction with the excimer laser.
    Myopia  over 8 diopters can usually be only partially corrected with the excimer laser. High myopia can be corrected by artificial lens implantation.
     
    In hyperopia up to 4 diopters, excimer laser treatment is producing good results. Up to 6 diopters satisfactory results can be expected.
     
    Astigmatism can often be treated satisfactorily with the excimer laser.

    Presbyopia can only be partially corrected today by surgery, so that after the age of 40 an additional visual aid, such as reading glasses will usually be required.

  • Refractive surgery is not itself a healing process but rather a method for the correction of vision problems that otherwise would be corrected with glasses or contact lenses.

    The correction values are based on the current state of the patient’s refractive conditions. This means that refractive surgery does not anticipate or correct for future changes in refraction. For any future changes, a complementary or new procedure can become necessary.
  • Good conditions for refractive surgery

    Aged over 22 with stable correction in the last 3 years.

    A strong motivation to do many things without glasses or contact lenses.

    Awareness of the patient that the result is subject to statistical fluctuations in refractive surgery and the maximum possible correction can not be achieved in each case. This may mean that most activities without glasses or contact lenses can be executed without problems, but sometimes a visual aid, such as glasses, must be accepted as a supplement.



  • Awareness of the patient that, after the age of 40 and even with normal eyes, different corrections are usually required for proximity and distance. There are techniques to reduce this problem surgically however these techniques still do not permit achievement of a perfect visual acuity for near and far. Therefore, the satisfaction level of patients after a presbyopia treatment is still limited. This means a willingness to accept a visual aid for certain activities, such as reading glasses.

    Good anatomical condition of the eyes in the preliminary investigations, including the corneal topography and corneal thickness (pachymetry).
  • Excimer laser surgery techniques and information

    We work with the latest technology and the latest laser with the full range of Schwind-Amaris, including wave-front-technology.
