iFS - Fifth Generation iLASIK technology
Better Technology for Better Vision

our Fifth Generation iLASIK devices

Not all lasers are created equal and having the best LASIK technology is pivotal to achieving the best vision and outcomes. The Orange County LASIK Institute is proud to offer Orange County's newest and most advanced fifth generation iLASIK technology.  The Intralase laser has long been the industry leader for all laser LASIK. The iFS is the newest upgrade of the the Intralase laser. Just as major software and cars can upgrade, so do the LASIK lasers. The advances of the iFS LASIK laser include increased speed and safety. Dr. Pham can make a flap in as little as ten seconds with this new and advanced technology. At the Orange County LASIK Institute, we are committed to providing the newest technology for our patients at our Irvine office.

The Advantages of the iFS Intralase over the fourth generation Intralase and Ziemer LASIK laser flap systems include:

  • Increased Flap Customization 
  • Increased Side Bevel Cut - Leading to stronger flaps
  • Increased Speed (250% faster) than the fourth generation Intralase. This increased speed reduces the risk of flap complications compared to the previous all laser systems. 
  • Elliptical Flap Option
  • Faster Corneal Regeneration and Healing
  • Decreased dryness over the fourth generation Intralase
  • Advanced Corneal Capabilities

Inverted Bevel-In Side Cut - Stronger FLAPS

cutting at 150 degrees makes strong flaps

  • The inverted Bevel-In Side cut is customizable up to 150 degrees. This promotes flap strength, replacement, and adhesion. It provides optimal biomechanical stability in the post-LASIK cornea.
  • Only Available in the iFS laser. It is not available for the Zeimer laser or the first four Intralase models
  • Stronger LASIK flaps
  • 3x more flap stability vs. a microkeratome during a flap lift
  • Decreased flap gutter
  • Nerves are closer so there is less loss of corneal sensitivity

Stronger FLAPS

Intralase iFS 140 degree side cuts rate as strongest force

  • The Fifth Generation iLASIK Flaps are almost 4x stronger than microkeratome flaps.
  • The Fifth Generation iLASIK Flaps are stronger than previous iLASIK flaps as well 

Increased Speed

  • 250% Faster than fourth generation technology. The iFS
  • Faster flaps for greater patient comfort
  • Less risks of suction breaks or patient movement
  • Less energy used due to increased speed.
  • Flaps created in approximately 10 seconds.  

Faster Patient Recovery

  • Compared to the fourth generation Intralase and other LASIK technology, patients have a faster recovery.
  • Patients also have less light sensitivity
  • Since the flaps are mechanically stronger, patients can resume most normal activities by the next day!

fifth generation Intralase leads to faster visual recovery
