Carl Zeiss has developed a new technique for the minimally invasive laser correction of vision defects

Home / ReLEx SMILE / Advantages

In recent years minimally invasive diagnostic and treatment methods have set new standards in modern medicine. This is because minimally invasive very often means minimum discomfort for the patient. In its ReLEx®  Smile method Carl Zeiss has developed a new technique for the minimally invasive laser correction of vision defects. This innovative treatment technique yields a whole range of benefits:

Flapless treatment

  • No folding back of a corneal flap• Lenticule preparation in the intact cornea
  • Minimally invasive access measuring just a few millimeters (80 % less lateral incision than in LASIK and Femto-LASIK)
  • Almost complete preservation of protective corneal layer (epithelium) and stabilizing outer corneal layers(Bowman’s membrane)
  • Maximum number of corneal nerves responsible for tear regulation remain intact• Practically painless during and after the procedure

Entire treatment carried out using femtosecond laser (all-femto)

  • Use of high-precision femtosecond technology
  • Outstanding predictability of results, even in cases of severe myopia (up to -12.50 D including -5.00D astigmatism)
  • Anatomically shaped contact glass avoids unnecessary compression of the cornea
  • No loss of vision during treatment
  • Noiseless and odorless treatment
  • Stabilization of visual acuity typically within 14 days

Single-step treatment

  • Entire laser correction in a single treatment step
  • No device change during the operation
  • Short procedure
