Good vision has a name: FreeVis.


For 30 years, the FreeVis LASIK Center Mannheim has been one of the leading eye laser centers in Europe. Our patients benefit from the expertise and experience of internationally recognized eye surgeon Professor Dr. Michael Knorz, who is considered a pioneer in refractive surgery. Whether it's Femto-LASIK, SMILE or lens implants, FreeVis utilizes the latest laser devices and technologies to enable you to live a life without glasses and contact lenses.

Eye Laser Surgery: Highest precision

With state-of-the-art laser devices, we can correct over 90% of all visual impairments, such as nearsightedness, farsightedness, and astigmatism, with the utmost precision.

» Femto-LASIK: Gentle and individually tailored
» SMILE: Minimally invasive surgery
» SmartSurf: A contactless laser procedure

Alternative treatment options: Lens Implants

Not all eyes are suitable for laser treatment due to very high refractive errors or anatomical peculiarities, such as a thin cornea. In these cases, we offer our patients artificial lenses as an alternative:

» Phakic lenses
» Laser lens exchange

Glasses-free vision, even after 40

We understand that good vision is an important factor for your well-being, regardless of your age. Thanks to modern technologies, we can now provide you with glasses-free, sharp vision for both near and far distances.

» Monovision
» Multifocal lens implants
» Laser lens exchange
