    ReLEx – Laser vision correction beyond LASIK

    Minimally invasive Laser Vision Correction

    With ReLEx® from SMILE, a lenticule and a small incision of < 6 mm is created inside the intact cornea, enabling an 80% smaller side-cut and 30% smaller cap cut, as compared to a LASIK flap.

    Explore the advantage of ReLEx SMILE from ZEISS

    • Minimally invasive surgery. 
      With ReLEx SMILE, a lenticule and a small incision of < 6 mm is created inside the cornea. The preservation of the upper corneal layers and the possibility for fewer transected nerves may preserve biomechanical stability and reduced the incidence of transient dry eye syndrome.
    • Single step. 
      With ZEISS ReLEx SMILE, the entire correction is performed as a single-step: one laser, one treatment plan and one laser process.
    • All-Femto. 
      Performed on a VisuMax® femtosecond laser, high precision, proven outcomes, predictability and ease of use are what ReLEx SMILE stands for.

    Treatment steps – Fast and gentle

    ZEISS ReLEx SMILE utilizes the high-precision femtosecond laser VisuMax from ZEISS to create a lenticule inside the cornea and access incision in a single treatment step. Its outstanding cutting precision, exceptional speed and gentle treatment approach make it an ideal platform for advanced corneal surgery applications such as SMILE.

    SMILE with VisuMax

    A refractive lenticule and small incision are created inside the intact cornea – all in one step.

    SMILE with VisuMax

    The lenticule is subsequently removed through this small incision, leaving the remainder of the superficial cornea intact.

    Removing the lenticule changes the shape of the cornea, thereby achieving the desired refractive correction.

    Benefits of ReLEx SMILE

    SMILE is a minimally invasive Laser Vision Correction procedure for myopia correction. During SMILE eye surgery, a lenticule is created inside the cornea using the ZEISS VisuMax femtosecond laser. Subsequently, the lenticule is extracted through a small incision, thereby achieving the desired vision correction.

    Minimally invasive Laser Vision Correction

    To achieve the refractive correction, with ZEISS ReLEx SMILE a small incision of < 6 mm is sufficient to remove the lenticule from the intrastromal layer of the cornea, thus preserving the corneal structure.

    Great integrity of the upper corneal layers

    With SMILE, the majority of the upper corneal layers remains intact. This offers the potential for preserving biomechanical stability. Besides the small incision, SMILE also allows the lamellar incision to be as small as possible, just slightly exceeding the effective optical zone diameter of the desired refractive correction.

    Easy postoperative management

    The excellent predictability of the refractive outcome leads to a low percentage of retreatments. Furthermore ReLEx SMILE reduces the incidence of infection and epithelial ingrowth, cumulating in overall fast healing.


    ZEISS ReLEx SMILE embodies precision, predictability, reproducibility and perfection. Using the femtosecond laser VisuMax, it creates a precalculated lenticule and incision with utmost accuracy and dependability.


    ReLEx SMILE saves time and increases comfort for surgeons and patients alike by performing the refractive correction with one treatment plan and on a single laser. Moreover, the lenticule inside the cornea and the access incision are created in a single step.

  • Clinical Data

    ReLEx SMILE – clinical results


    ReLEx smile - clinical results

    The clinical study reports on the results of the ReLEx SMILE procedure for the correction of myopia (6 month results).

    Background and method

    • 328 eyes were analyzed and evaluated in five study centers
    • All the eyes had a best-corrected visual acuity of 20/20 or better before the operation


    • Consistent results with outstanding predictability
    • Very close to target refraction
    • Valid across entire range of correction, from low to high-level myopia


    88% of all patients with a preoperative best-corrected visual acuity of 20/20 or better achieved uncorrected visual acuity of 20/20 or better after surgery.


    Impressive stability of the refractive correction (MRSE)


    • 98.5% of all patients achieved target refraction within the typical “satisfaction zone” (± 1.00 D)
    • 93% of all patients achieved target refraction with a precision of ± 0.50 D
