Bladeless Lasik - iLasik

Detailed comparison to traditional Lasik.

Click to see video of Bladeless 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.

Analysis of planned and postoperatively measured flap thickness after LASIK using the LenSx multifunctional femtosecond laser system.

J Refract Surg. 2014 Sep;30(9):622-6

Authors: Juhasz E, Filkorn T, Kranitz K, Sandor GL, Gyenes A, Nagy ZZ

PURPOSE: To evaluate LASIK corneal flaps using a multifunctional femtosecond laser suitable for cataract and corneal surgery (LenSx; Alcon Laboratories, Inc., Aliso Viejo, CA) and to compare the planned and postoperatively measured flap thickness using an anterior segment optical coherence tomography device (AS-OCT).
METHODS: Twenty patients (38 eyes) diagnosed as having myopia and myopic astigmatism were enrolled. LASlK was performed using the LenSx femtosecond laser for intracorneal flaps and the Wavelight Allegretto 400 excimer laser (Alcon Laboratories, Inc.) for intra- stromal photoablation. Desired flap thickness and diameter were 140.0 + 0.0 pm and 8.5 + 0.0 mm, respectively, whereas mean ablation depth and diameter of the excimer laser treatment were 67.9 ± 24.18 pm and 6.5 ± 0.08 mm, respectively. Entered data of the LenSx femtosecond laser were used to determine desired flap thickness, whereas AS-OCT (RTVue; Optovue, Inc., Fremont, CA) was used to measure flap thickness postoperatively. The Wilcoxon signed-rank test, dependent paired t test, and Friedman test were used for comparison of dependent and repeated measures.
RESULTS: There was no statistically significant difference in the planned and postoperatively measured flap thickness (140.0 ± 0.0 vs 140.28 _ 8.0 pm; P = .4067). Interfaces of the flaps had even surfaces according to the images and calculations on the AS-OCT device (P = .058).
CONCLUSIONS: Application of this multifunctional femtosecond laser performing LASIK proved to be a safe and effective method regarding predictability of flap thickness.
