What is Z-LASIK (Ziemer Femtosecond Laser)?

The Ziemer FEMTO LDV Laser of Z-LASIK is the latest blade-free vision correction technology used for creating the corneal flap. The Ziemer laser is the latest IntraLASIK system from Switzerland that delivers unparalleled precision and accuracy during all-laser LASIK surgery.

How Does Z-LASIK Work?

The Ziemer FEMTO LDV laser applies a focused, low-energy laser beam to the surface of the eye to create microscopic bubbles at a precise depth within the cornea. The laser energy is delivered through a lens that is held against the eye, causing the separation of a thin layer of the cornea and creating the LASIK flap.


The Ziemer FEMTO LDV laser offers tremendous control, thereby allowing Dr. Burns to create a LASIK flap of desired thickness, size, orientation, and location that is unique to each patient’s eye and vision correction needs. The laser uses ultra-fast, tightly focused laser beams to create microscopic bubbles within the cornea. The bubbles disappear immediately after the flap is lifted, creating a smooth surface that is essential in the self-sealing process of the corneal flap after LASIK.
When compared to other types of femtosecond lasers, the Ziemer FEMTO LDV laser offers the following benefits:

    Increased speed, safety, and accuracy.
    Increased likelihood of 20/20 vision or better.
    Reduced risk of flap complications.
    Reduced possibility of poor nighttime vision.

Are You a Good Candidate for LASIK Eye Surgery?

While many patients who come to see Dr. Burns in San Diego qualify for LASIK eye surgery, the procedure is not for everyone. The following qualities make an ideal patient for LASIK Eye Surgery:

  • At least 18 years or older.

  • checkup

    Candidates should be in generally good health.

  • Eyes are healthy and free from disease or abnormalities like infections or scars.

  • Candidates’ vision needs to be consistent for at least a year before surgery date.

Some additional factors that may prevent certain patients from having LASIK surgery include thin Corneas, large Pupils, and Keratoconus (Bulging Cornea). More serious vision problems, such as advanced Glaucoma, might disqualify the potential patient altogether. Only a one-on-one consultation with an experienced LASIK specialist like Dr. Burns can help you decide if you can benefit from LASIK Eye Surgery.
