How does AMO’s IntraLase FS Femtosecond Technology contribute to LASIK success? The Intralase FS Femtosecond Laser delivers biomechanical superiority, excellent visual acuity, and unmatched safety. The Intralase FS is an innovative technology also well suited for creating uniquely shaped corneal incisions for corneal transplant surgery.
Intralase FS Biomechanically Superior Flap Creation
Maintaining the integrity of the corneal biomechanics is a critical element in the success of the refractive procedure — and only AMO IntraLase FS Laser system delivers unmatched control over flap diameter, depth, centration and morphology, resulting in an unprecedented combination of potential advantages, including:
• Intralase FS Controlled Flap Structure
• Precisely centered, accurately sized flaps; programmable hinge placement
• Flap dimensions designed based on patient factors, such as corneal thickness, steepness, diameter and pupil position
• Precise control of flap dimensions helps avoid the peripheral lamellar structure, vital to the biomechanical stability of the cornea
• Intralase FS Uniform Flap Thickness
• Uniformly thin, planar flaps
• Smooth, evenly hydrated, stromal morphology
• Reproducible flap thicknesses with profiles that are significantly superior to those achieved by mechanical means (p<0.001)
• Maximized residual stromal beds
• Intralase FS Superior Visual Outcomes
• Rapid visual recovery
• Day 1: UCVA 20/16 or better in 70% of patients (n=199)
• Month 1: Increased contrast sensitivity at all spatial frequencies vs. baseline (n=88)
• Better quality of vision
• Eyes treated with the IntraLase FS Laser system had fewer visual disturbances (haze, glare, sensitivity), less pain, and less dryness than a microkeratome
Intralase FS Faster Visual Acuity Than Surface Treatments
In a recent study, Intralase FS treated eyes demonstrated clinically and statistically better visual acuities (uncorrected and best corrected) through one month postop compared to surface treatment.
• Uncorrected Vision
• Through one week postop, eight times more IntraLase FS eyes achieved 20/20 or better uncorrected vision compared to PRK eyes
• Superiority continued at one month, where 45% more IntraLase FS eyes achieved 20/20 or better uncorrected vision compared to PRK eyes
• Best Corrected Vision
• Clinically and statistically significant improvement through one month with LASIK with the IntraLase FS method over PRK when comparing baseline BCVA and postop BCVA
• At one month, more than twice as many IntraLase FS eyes showed BCVA gain compared to PRK eyes
Intralase FS Precision Technology For A Safer LASIK Experience
By replacing the blade commonly used for corneal flap creation with a Femtosecond Laser, AMO has made LASIK eye surgery safer than ever before. The IntraLase FS Laser system delivers micron-level accuracy 100% greater than a microkeratome for more accurate and consistent flap thickness — which is critical for a successful LASIK outcome.
Retrospective analysis comparing LASIK results with IntraLase FS technology versus the two leading microkeratomes demonstrated that IntraLase FS Laser System performed better in three areas important to LASIK results and safety: flap thickness, induced astigmatism, and cell injury. There are fewer flap-related complications with the IntraLase FS method:
• Minimal risk of sight-threatening events (free caps, globe penetration, buttonhole flaps, decentered flaps, and/or incomplete cuts)
• No risk of corneal abrasion
• Reduced risk of dry eye
Intralase FS Innovative-Shaped Corneal Incisions
IntraLase FS enabled keratoplasty gives surgeons the ability to precisely create uniquely shaped corneal incisions — opening a new era in corneal transplantation and delivering the potential for faster healing and improved visual recovery. Leading corneal surgeons have demonstrated that this technology advancement enables:
• Surgeons to create straight, angled and arcuate incisions within the cornea
• Multiplanar custom incisions with hermetic sealing properties that require less suture tension
• Less suture tension can result in less astigmatism
• Multiplanar custom incisions provide larger wound surface area for stronger healing
• Laser resectioning that produces more rapid healing
• Earlier suture removal and rapid visual rehabilitation
