Bladeless Lasik - iLasik

Detailed comparison to traditional Lasik.

The femtosecond laser creates a series of bubbles within the cornea that when combined make the Lasik flap. Click for video.  
   

Bladeless Lasik, also called "iLASIK or Bladeless Lasik, is exactly like traditional conventional or custom wavefront Lasik, except the corneal flap is created with a femtosecond laser microkeratome rather than a mechanical microkeratome with a metal blade.

Conventional or Wavefront

Bladeless/Bladeless Lasik may be performed with conventional laser ablation or wavefront-guided custom Lasik laser ablation.

Potential Advantage

There are several advantages to Bladeless/Bladeless Lasik that can make Lasik more predictable and safer than traditional Lasik with a mechanical microkeratome, however there are limitations and a unique set of concerns that need to be evaluated.

Advantages include more precise positioning of the flap, more accurate thickness of the flap, more even thickness of the flap throughout, and a lower probability of intraoperative complications such as buttonhole flaps, thin/thick flaps, or epithelial defect. Recent studies have shown Bladeless/Bladeless Lasik to be more favorable than Lasik with a mechanical microkeratome in providing vision with better contrast sensitivity.

Potential Disadvantage

Some patients, but not all, experience a short period of increased corneal edema with Bladeless/Bladeless Lasik. This slight swelling can cause vision to be blurry, but the swelling normally resolves with healing. Occasionally an Bladeless/Bladeless Lasik patient will experience some photosensitivity. All these issues usually resolve during the normal Lasik healing process, however additional eye drop medication may be required.

Occasionally Required

Bladeless/Bladeless Lasik is an option for nearly all who decide to have refractive surgery with a corneal flap, but Bladeless/Bladeless Lasik may be a requirement for individuals with preexisting epithelial defects, large pupils, thin corneas, poor contrast sensitivity, or other physiological reasons that indicate the greater accuracy and safety of Bladeless/Bladeless Lasik is required.

Looking For Best Lasik Surgeon?

If you are ready to choose a doctor to be evaluated for conventional or custom wavefront Lasik, Bladeless Lasik, PRK, or any refractive surgery procedure, we recommend you consider a doctor who has been evaluated and certified by the USAEyes nonprofit organization.

Corneal backscatter analysis by in vivo confocal microscopy: fellow eye comparison of small incision lenticule extraction and femtosecond laser-assisted LASIK.

Abstract
Purpose. To evaluate and compare corneal backscatter from anterior stroma between small incision lenticule extraction (SMILE) and femtosecond laser-assisted LASIK (femto-LASIK). Methods. A cohort of 60 eyes of 30 patients was randomized to receive SMILE in one eye and femto-LASIK in the fellow eye. In vivo confocal microscopy was performed at 1 week and 1, 3, and 6 months after surgery. The main outcome measurements were maximum backscattered intensity and the depth from which it was measured, the backscattered light intensity 30  μ m below Bowman's membrane at the flap interface and 150  μ m below the superficial epithelium, and the number of refractive particles at the flap interface. Results. The mean backscattered light intensity (LI) at all measured depths and the maximum backscattered LI were higher in the SMILE group than the femto-LASIK group at all postoperative visits. LI differences at 1 week and 1- and 3-month visits were statistically significant (P < 0,05). LI differences at 6 months were not statistically significant. There was no difference in the number of refractive particles at the flap interface between the groups at any visit. Conclusions. SMILE results in increased backscattered LI in the anterior stroma when compared with femto-LASIK were evaluated.
