IntraLase Technology
Truly Customizable Architecture
The IntraLase FS and iFS Laser Systems are ophthalmic
surgical lasers indicated for use in patients undergoing surgery or
treatment requiring the initial lamellar resection of the cornea.
For safety information, please see inside.
IntraLase Technology:
Two Innovative Femtosecond Laser Platforms
iFS Advanced Femtosecond Laser System
AMO’s latest laser platform has all the features of the IntraLase FS System, plus:
u
Increased speed
u
Enhanced flap-customization capabilities
– Inverted bevel-in side cut
– Elliptical flap option
– Advanced corneal capabilities
IntraLase FS Femtosecond Laser System
u
Provides unparalleled uniformity and precision, biomechanical stability and an unsurpassed safety profile
u
Enables physicians to customize flap parameters such as depth, edge angle and centration
Both femtosecond laser systems embody IntraLase Technology, an essential component of the iLASIK Solution.
The IntraLase FS and iFS Laser Systems are ophthalmic surgical lasers
indicated for use in patients undergoing surgery or treatment requiring the initial
lamellar resection of the cornea. Contraindications may include corneal edema,
glaucoma, and keratoconus. Risks and complications may include corneal pain,
flap tearing, and epithelial ingrowth. Patients are requested to consult with their
eye care professional for a complete listing of contraindications and risks. U.S.
Federal Law restricts this device to sale, distribution, and use by or on the order
of a physician or other licensed eye care practitioner.
iFS Femtosecond Laser
IntraLase FS Femtosecond Laser
Advanced Capabilities from the
iFS Femtosecond Laser
The iFS Laser System has all the features of the IntraLase FS System, plus increased speed and enhanced
flap-customization capabilities that include:
u
Inverted bevel-in side cut up to 150° for optimal biomechanical stability1
u
Elliptical flap option to maximize stromal bed exposure
u
Tighter spot separation provides smoother stromal beds and a virtually effortless flap lift2
u
Lower energy per pulse, which may reduce tissue response and inflammation
u
Higher repetition rate and faster procedure time, which enhance patient comfort and confidence
u
High-resolution video microscope for maximum surgeon comfort
Inverted Bevel-In Side Cut
u
Increased flap adhesion post-operatively for optimal wound healing1
u
3x more flap stability (150° side cut) vs. microkeratome during flap lift1
u
Significantly reduced flap gutter3
u
Improves severed nerve apposition3
u
Less of a reduction in corneal sensitivity3
u
Fewer dry eye signs and symptoms than with the 30° side cut3
30° side cut slows nerve regeneration
post-operatively3
Inverted bevel-in side cut, customizable to 150°, promotes flap
replacement, positioning and adhesion for optimal biomechanical
stability of the post-LASIK cornea1
150° side cut promotes faster nerve
regeneration post-operatively3
“With the added speed of the iFS Laser, I am now placing tighter pulses and
bevel-in edges, allowing me to create flaps that are faster and easier to lift,
with smoother beds and increased stability.”

Elliptical Flap Enhances Surgical Options
u
Distributes forces symmetrically to the elliptical cornea
u
oves the hinge peripherally to maximize stromal bed exposure for full delivery of excimer ablation and
M
reduces chance of ablating the hinge2
u
Allows use of a wider hinge angle2
u
May spare some corneal collagen fibers to enhance biomechanical stability2

140˚ Side Cut
In New Zealand White rabbit eyes, three groups of flaps were created with either
the AMADEUS™ microkeratome, iFS Laser 70° side-cut angle, or iFS Laser
140° side-cut angle. At 3 months, a force gauge was attached to a curved
lens and pulled perpendicularly until the flap dehisced and peak force could
be measured. Note the IntraLase FS Laser has a side-cut angle up to 90°.

Enhanced Safety with Unparalleled
Uniformity and Precision
With over 3.5 million procedures and counting, “all-laser” IntraLase Technology offers numerous safety advantages
over microkeratome technology, both during flap creation and post-operatively.
Flap Creation Safety Advantages
Reduces or eliminates several complications, including:6-8
u
Buttonhole or free flaps
u
Irregular flaps
u
Microperforations
u
Decentered flaps
u
Epithelial defects
Furthermore, higher laser speed reduces time under suction,
which means:2
u
Less risk of suction break
u
Less time during which the eye experiences elevated
intraocular pressure
u
Less potential for subconjunctival hemorrhages
Unparalleled Uniformity and Precision Give You the Ability to Precision-Design
Your Patients’ Intracorneal Architecture
The unique computer-controlled laser system enables surgeons to create thin, planar flaps with a uniform mean
thickness of 112 ± 5 µm and an average standard deviation of as little as 4 µm within each flap,9 maximizing residual
bed and potentially producing a more stable post-LASIK cornea.

The IntraLase FS and iFS Laser Systems are ophthalmic surgical lasers indicated for use in the creation of a lamellar cut/resection
of the cornea for lamellar IntraLase Enabled Keratoplasty (IEK), for the creation of a penetrating cut/incision for penetrating IEK,
and for corneal harvesting. Contraindications may include any corneal opacity adequately dense to obscure visualization of the iris,
descemetocoele with impending corneal rupture, previous corneal incisions that might provide a potential space into which the
gas produced by the procedure can escape, and cornea thickness requirements that are beyond the range of the system. Patients
are requested to consult with their eye care professional for a complete listing of the contraindications and risks. U.S. Federal Law
restricts this device to sale, distribution, and use by or on the order of a physician or other licensed eye care professional.

“We’ve done some studies with the iFS Femtosecond Laser. It’s like night and
day compared to anything else I’ve ever used.”

erry D. Solomon, MD
Carolina Eyecare Physicians, LLC

“These studies were statistically significant and certainly suggest that the
inverted bevel-in side cut design of the iFS flap is far more stable than
mechanically created flaps. The ability to precisely create truly customized
flaps for every patient further validates the iLASIK Procedure.”

“Corneal surgery is rapidly evolving towards disease-specific surgery. IEK
is part of this evolution; breakthrough technology allows complex incision
patterns which are reproducible between donor and recipient, or eye
bank and doctor. IEK also enables surgeons to choose the pattern
most consistent with a patient’s underlying problem.”

“The bottom line is that IntraLase Technology is a tried and true system.
It works, it’s consistent and it gets excellent results. It’s years ahead of
any of the other platforms.”

Laser assisted in-situ keratomileusis (LASIK) can only be performed by a trained ophthalmologist and for specified reduction
or elimination of myopia, hyperopia, and astigmatism as indicated within the product labeling. Laser refractive surgery is
contraindicated for patients: a) with collagen vascular, autoimmune, or immunodeficiency diseases; b) who are pregnant or
nursing women; c) with signs of keratoconus or abnormal corneal topography; d) who are taking one or both of the following
medications: Isotretinoin (Accutane®) and Amiodarone hydrochloride (Cordarone®). Potential side effects to laser refractive
surgery may include glare, dry eye, as well as other visual anomalies. LASIK requires the use of a microkeratome that cuts a flap
on the surface of the cornea, potential side effects may include flap related complications. Patients are requested to consult with
their eye care professional and Patient Information Booklet regarding the potential risks and benefits for laser refractive surgery,
results may vary for each individual patient.
Restricted Device: U.S. Federal Law restricts this device to sale, distribution, and use by or on the order of a physician or
other licensed eye care practitioner. U.S. Federal Law restricts the use of this device to practitioners who have been trained in
its calibration and operation and who have experience in the surgical treatment and management of refractive errors.
