iFS Advanced Femtosecond Laser

All of our femtosecond expertise culminates in our 5th-generation iFS™ Laser. The iFS™ Laser gives surgeons greater control for maximum customization — providing an indispensible tool for LASIK and beyond. With over 5 million procedures performed to date, IntraLase® Technology is the femtosecond technology of choice.

Flap Architecture Innovations

The iFS™ Laser brings two major innovations in flap architecture: the inverted bevel-in side cut and elliptical-shaped flaps. When combined with a faster repetition rate and tighter spot/line separation, our 5th-generation iFS™ Laser is a versatile tool that preserves corneal innervation and allows post-operative healing by creating a biomechanically stable corneal flap.

  • Inverted bevel-in side cut up to 150° for improved biomechanical stability


  • Elliptical flap option to maximize stromal bed exposure


  • Tighter spot separation provides smoother stromal beds and a virtually effortless flap lift
  • Lower energy per pulse, which may reduce tissue response and inflammation
  • Advantage of the Oval Flap: Corneas are naturally oval shaped. So naturally the flap that is created should be oval shaped as well, right? Up until now, previous lasers have cut a generic circle flap. But that is where the iFS™ Advanced Femtosecond Laser sets itself apart from the rest, by bringing an innovative new oval flap creation technique. The results are preserved corneal nerves, better biomechanical stability, and the ability to locate the flap size and location to the exact area of the cornea needing treatment. The oval flap also gives our surgeons an advantage when dealing with farsightedness and astigmatism, an advantage that was previously unavailable.
  • Greater Biomechanical Stability and Faster Visual Recovery. The iFS™ Laser provides the ideal combination of advantages: minimal disruption of corneal architecture, stronger flaps, fewer possible complications plus faster visual recovery.
  • Customized Corneal Capabilities: The iFS™ Laser brings advanced corneal options within reach, including intrastromal ring implantation and channels*, as well as IntraLase®-Enabled Keratoplasty. With the iFS™ Laser, surgeons have the ability to create accurate, reproducible incisions in an almost limitless range of shapes and patterns.
  • IntraLase-Enabled Keratoplasty: IntraLase® Technology is the first in the world used to create innovative-shaped corneal incisions for full-thickness corneal transplants.
  • Precisely shaped angled edges fit snugly to improve alignment. Provides a smooth corneal contour with greater surface area to speed wound healing


At PVSC, we have always prided ourselves on offering our patients state-of-the-art technology, which is why we are excited to introduce the incredible iFS™ Advanced Femtosecond Laser. Previous lasers used have been highly efficient and safe, but like trading in a reliable vehicle for a high performance sports car, the upgrade to the 5th generation of iFS™ Advanced laser allows for a faster, smoother, more controlled LASIK procedure than ever before. Your custom LASIK experience at Texas Eye and Laser Center will truly be an eye opening experience, leaving you with amazing, clear vision and a newfound freedom.


Speed Equals Results

The iFS™ Laser gives surgeons and patients a combination of advantages including stronger flaps, fewer possible complications and faster visual recovery.

Ophthalmologists using the first experimental femtosecond lasers worked with technology that operated at 2 kHz and took 5 minutes to create the necessary corneal flap. Today, with the 5th generation iFS™ Advanced Femtosecond Laser, our surgeons are operating at 150 kHz and can create the flap in just 8 seconds! This is approximately 2 ½ times faster than the previous model. The important thing to remember is that speed does not mean less control. In fact speed is an asset and allows for greater control and less chance the patient experiences any discomfort. With the inverted side-cut technology, the corneal flap virtually “locks” into place, creating even more corneal stability.

Additionally, the higher rate of speed allows for less energy to be used on each laser pulse, which can leads to a overall better outcome and experience. The main benefits can be seen with faster healing times, improved corneal stability, smooth corneal surface, and clear vision sooner rather than later. Speed equals less discomfort and a smoother overall procedure.

What is the IntraLase Method?

The IntraLase Method is a 100% blade-free approach to creating your corneal flap—the thin flap of tissue that the doctor folds back in order to perform your LASIK procedure.

How does it differ from other methods of creating a corneal flap?

The only other way to create a corneal flap is by using an instrument called a microkeratome. A microkeratome is a hand-held steel blade that makes a cut as it travels across the cornea. With the IntraLase Method, a blade never touches your eye.

How does the IntraLase Method work?

Tiny pulses of laser light pass harmlessly through the outer portion of your cornea and form a uniform layer of microscopic bubbles just beneath the surface of your eye. Just prior to LASIK surgery, the doctor can lift the corneal flap by gently and easily separating the tissue where these bubbles have formed.

Besides being blade free, what other benefits are there to the IntraLase Method?

The IntraLase Method virtually eliminates the most severe sight-threatening complications. While LASIK complications are rare, when they do occur they are primarily related to the use of the microkeratome. The IntraLase Method is 100% blade-free, exceptionally advanced, and has been shown to improve outcomes for  more patients. And patients report better quality of vision overall, particularly interms of their ability to see well in low light.

Is the IntraLase Method proven?

To date, the IntraLase Method has been used in hundreds of thousands of LASIK  procedures around the world.

How long does it take to create a flap using the IntraLase Method?

The creation of the flap itself takes only about 15-20 seconds per eye. Including preparation time, the LASIK procedure takes about 10 minutes total.

Is it painful?

No—the doctor applies drops to numb the eye.

What’s the reaction of patients who have experienced the IntraLase Method?

In a clinical survey, the vision in the IntraLase-treated eye was preferred by LASIK  patients 3-to-1 over the vision in the microkeratome-treated eye (among those who stated a preference).
