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.

Effect of suction on macular and retinal nerve fiber layer thickness during femtosecond lenticule extraction and femtosecond laser-assisted laser in situ keratomileusis.

J Cataract Refract Surg. 2014 Oct 9;

Abstract
PURPOSE: To compare the effect of suction on macular and retinal nerve fiber layer thickness during femtosecond lenticule extraction and femtosecond laser-assisted laser in situ keratomileusis (LASIK) with the Visumax FS system.
SETTING: Ophthalmic Center, Beijing Tongren Hospital, Capital Medical University, Beijing Ophthalmology & Visual Sciences Key Lab, Beijing, China.
DESIGN: Prospective comparative case series.
METHODS: Fourier-domain optical coherence tomography was used to measure macular and retinal nerve fiber layer thickness preoperatively and through 6 months postoperatively.
RESULTS: The study evaluated 196 eyes. In the femtosecond lenticule extraction group, the mean foveal, parafoveal, and perifoveal retinal thicknesses 1 day and 1 week postoperatively were diminished, although the changes were not statistically significant. The retinal thickness did not change significantly 1, 3, or 6 months postoperatively (P>.05). In the LASIK group, the mean foveal, parafoveal, and perifoveal retinal thicknesses did not change significantly at any postoperative timepoint (P>.05). The differences in all 3 retinal thicknesses between the 2 groups were not significant 1, 3, or 6 months postoperatively (P>.05). The ganglion cell complex and retinal nerve fiber layer thickness did not change significantly from preoperatively to any postoperative timepoint in either group (P>.05).
CONCLUSION: Suction had no significant clinical effects on the macular thickness and retinal nerve fiber layer during femtosecond lenticule extraction or femtosecond laser-assisted LASIK.
