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.

[Comparison of Visual Acuity and Higher-order Aberrations after Standard and Wavefront-guided Myopic Femtosecond LASIK].

Cesk Slov Oftalmol. 2015 Feb;71(1):44-50

Authors: Anderle R, Ventruba J, Š S

PURPOSE: To analyze and compare visual acuity, refractive outcomes and higher-order aberrations after standard and wavefront-guided Femto-LASIK at 1, 3, and 12 months postoperatively.
METHODS: Study of 95 consecutive eyes of myopic patients (-0.5 to -7.0 D), who underwent Femto-LASIK with standard ablation profile (STA) (49 eyes) or wavefront-guided ablation (WFG) (46 eyes) using femtosecond laser LDV Ziemer and excimer laser MEL 80 Zeiss with iris registration. Primary outcome measures were uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refraction and higher-order ocular aberrations (HOAs). HOAs were measured with Hartmann-Shack wavefront aberrometer WASCA, HOAs analyzed at 6 mm pupil, assessed total HOAs root mean square (RMS HOAs) and individual Zernike coefficients.
RESULTS: Preoperatively, there were no significant differences between STA and WFG groups in UDVA, CDVA, manifest refraction or HOAs. As compared with preoperative values, spherical aberration Z(4,0) increased by 0.24 µm in both groups and it is the main increasing factor of RMS HOAs (0.05 µm in STA group and 0.08 µm in WFG group). Safety and efficacy index is 1.0 in both ablation profiles. Postoperatively, median UDVA and CDVA achieved 1.2. No patient lost line of CDVA at 12 month postoperatively. All patients were within ± 0,5 D of emmetropia at 12 months. Significant differences were not found between STA and WFG in UDVA, CDVA, manifest refraction or HOAs at 1, 3 and 12 month.
CONCLUSIONS: Both wavefront-guided and standard Femto-LASIK with LDV and MEL 80 platform have shown very good efficacy and safety. Myopic Femto-LASIK only slightly increases RMS HOAs, especially by induction of spherical aberration. Both methods have equivalent postoperative aberration score one year postoperatively.Key words: femtosecond LASIK, higher-order aberrations, wavefront-guided, visual accuity.
