The Technology Behind LASIK Success

How does AMO's IntraLase FS Technology contribute to LASIK success? By delivering biomechanical superiority, excellent visual acuity, and unmatched safety. This innovative technology is also well suited for creating uniquely shaped corneal incisions for corneal transplant surgery.

There's Only One IntraLase FS Laser System

Increasingly, successful LASIK procedures have one thing in common — they use AMO's IntraLase FS Laser System. IntraLase  FS Technology clearly delivers clinical advantages to enhance your practice.

Our 4th-generation laser is designed as a primary laser for LASIK procedures and advanced corneal surgery procedures

• 60 kHz performance delivers microkeratome speed and laser precision 
• Better biomechanical stability vs. a microkeratome (1) 
• Lower induced high-order aberrations vs. a microkeratome (2) 
• Better refractive outcomes vs. a microkeratome (2) 

At a nearly unprecedented level, LASIK has become a trusted way for people to improve their functional vision. And judging by the numbers, the IntraLase Method, using AMO's IntraLase FS Technology, has become an integral part of today's advanced LASIK procedure. With well over 1 million procedures completed to date, IntraLase FS Technology is clearly in the DNA of your successful practice. This seemingly genetic link between IntraLase FS Laser System and your LASIK practice exists because:

• Patients want all-laser LASIK, and we're the all-laser pioneers 
• Surgeons believe in the safety, effectiveness and profitability profile of the IntraLase FS laser 
• The future of refractive surgery hinges on the innovative application of scientific breakthroughs, and IntraLase FS Technology is at the forefront 

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:

• 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 
• 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 
• 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 

Uncorrected Vision

 
Through one week postop, eight times more IntraLase eyes achieved 20/20 or better uncorrected vision compared to PRK eyes 
Superiority continued at one month, where 45% more IntraLase 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 Method over PRK when comparing baseline BCVA and postop BCVA1
At one month, more than twice as many IntraLase eyes showed BCVA gain compared to PRK eyes

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 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 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
