What is Zeiss SMILE's Patent Technology: Side Cut?

                     What is Zeiss SMILE's Patent Technology: Side Cut?

Recently, lenticular extraction methods (3rd generation) for vision correction, such as Zeiss' SMILE LASIK, have gained attention.

The separated corneal stroma (lenticule) through 3rd generation vision correction

For those unfamiliar with the term "lenticule," the 3rd generation vision correction method does not remove the corneal stroma like LASIK or LASEK. Instead, it separates it into a lens-like shape and extracts it through a tiny incision to correct refraction. This lens-shaped corneal stroma is called a "lenticule."

SMILE LASIK, the first lenticule extraction method, is only possible with Zeiss' VisuMax equipment, which is equipped with 240 technology patents related to SMILE LASIK.

Side Cut is one of the 240 technology patents 

The "Side Cut" is one of these 240 technology patents. It prevents smooth separation of the lenticule to avoid damaging other parts of the eye. If the edges of the lenticule are made too thin, it can cause severe side effects like tearing or ripping.

The SMILE LASIK, a 3rd generation lenticular extraction method, is a reliable vision correction procedure with 240 patents registered by Zeiss over the past 15 years. Many lenticular extraction technologies and know-how, including the Side Cut, are integrated into the VisuMax.

When considering new vision correction equipment, it is essential to focus not just on whether it is the latest model, but on how long the procedure has been researched, what technologies are included, and how reliable the clinical data is.

The VisuMax has successfully performed 8 million lenticule separations worldwide using the Side Cut. The FDA approval signifies that its safety has been thoroughly reviewed and that it is recognized as a reliable procedure in the field of vision correction. The Side Cut is a unique patented technology of Zeiss' VisuMax.

Therefore, lenticule separation methods used by other vision correction equipment, cannot achieve the same clinical results as the VisuMax. Additionally, the fact that only Zeiss' SMILE LASIK has received FDA approval supports the reliability of the Side Cut technology.

Today, we explored Zeiss SMILE's unique technology, the Side Cut. We will continue to introduce in-depth topics on vision correction procedures.
