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.

Possible risk factors and clinical effects of an opaque bubble layer created with femtosecond laser-assisted laser in situ keratomileusis.

J Cataract Refract Surg. 2015 Jul 23;

Authors: Jung HG, Kim J, Lim TH

Abstract
PURPOSE: To report the risk factors and clinical effects of an opaque bubble layer (OBL) during creation of a laser in situ keratomileusis (LASIK) flap with the Visumax 500 kHz femtosecond laser.
SETTING: HanGil Eye Hospital, Incheon, South Korea.
DESIGN: Retrospective comparative study.
METHODS: Visual acuity, manifest refraction, intraocular pressure, corneal curvature, corneal thickness, and optical quality were evaluated. To prove a previous hypothesis that the harder a surgeon applanates during flap creation (hard-docking technique), the higher the incidence of OBL, the area of the meniscus on the cornea to which pressure was applied by the patient interface was calculated. Eyes were separated into 2 groups; that is, OBL-occurrence group and OBL-free group. Clinical outcomes in the 2 groups were compared to measure the risk factors and clinical effects of an OBL.
RESULTS: The study included 827 myopic eyes. The incidence of OBL was 5.0% (41 eyes). The mean flat keratometry was steeper and the preoperative cornea thicker in the OBL-occurrence group. The OBL-occurrence group had harder applanation (ie, a larger area of meniscus) than the OBL-free group. The incidence of OBL was higher in the hard-docking technique. Clinical outcomes, including refractive error, visual acuity, and optical quality, in the 2 groups were not statistically significantly different 1 month after LASIK.
CONCLUSIONS: The incidence of OBL was 5.0%. A steep, thick cornea and a hard-docking technique could be risk factors for an OBL. The OBL did not appear to affect optical quality or visual outcomes.
