iLASIK - San
Diego's Fifth Generation LASIK Technology
Better Technology, Better Results, Better Vision!
Potential Outcomes Beyond 20/20!
The San Diego LASIK Institute is proud to offer San Diego fifth
generation iLASIK surgery. We combine the state of the art Intralase LASIK laser called the iFS
and the Advanced Custom Wavefront technology of the Visx Star S4 laser to provide our San Diego patients with
the pinnacle of laser vision correction technology. There are only a handful of iFS lasers throughout the world.
The iFS laser makes the flap in your LASIK surgery in less than ten seconds. It is 250% faster than other
Intralase lasers used in San Diego and throughout the country. This increased speed leads to more comfort and
safety for your LASIK procedure.
iDesign LASIK involves three lasers - the iDesign advanced custom wavescan, the iFS fifth generation (bladeless) laser, and the VISX Star S4 with Iris Registration. We have recently upgraded to the newest
iDesign 2.0 system. Learn more here.
iFS and iLASIK Facts - Revolutionary all
laser LASIK Flap Technology
1. Unprecedented Speed - Increased Comfort and Safety
• Increased patient comfort
• Reduced risk of suction loss
• Less exposure to eye pressure
The iFS Intralase laser runs at a speed of 150kHz. This is 250%
faster than the speed of other Intralase lasers in San Diego. The remarkable speed of the iFS Intralase laser
allows us to make your LASIK flap in as little as 10 seconds! The most uncomfortable part of your San
Diego LASIK procedure is making the flap. With a faster speed, the discomfort most of our patients feel is very
2. Less Laser Energy - Better Flaps Due To Inverted Bevel Side
The inverted side cut angle shown here greatly increases flap
strength. The additional flap engineering benefits include:
• Smother Optical Surface
• Healthier Cornea After Surgery
• Better Eye Tracking
• Less Risk for Light Sensitivity
3. The San Diego LASIK Institute's iFS lasers make Stronger
• Stronger healing
• Greater Flap Stability
• Inverted bevel side-cut angle
• Oval Shaped Flap
• Less Corneal Dryness
Comparing the Strengths of Flaps made with Microkeratome and the iFS Intralase laser. Intralase iFS made flaps
are over 300% stronger!
Frequently Asked Questions About the iFS Intralase LASIK
I have seen many advertisements for "All Laser" or "Bladeless"
LASIK, is this the same as the iFS laser?
Not all "bladeless" LASIK is the same. Although Intralase was
the first all laser treatment, the iFS is the fifth generation of the Intralase laser. The San Diego LASIK
Institute is the first one to have it in San Diego. Please be sure to ask for the iFS laser by name. The
previous version of the Intralase was called the FS laser so it is easy to get confused by the similar name.
Also, you can ask for the speed of the laser as well to make sure that it is the iFS laser which runs at
150 kHz. The iFS laser has unprecedented speed and safety.
Is the iFS Laser more expensive?
At the San Diego LASIK Institute, we are committed to using the
best and safest LASIK technology today. We believe that good vision is priceless and we have committed to using
the best technology even if it costs us more to do it. We will never let cost concerns dictate the quality of
our care. Although the iFS laser is the most advanced and costly femtosecond laser for us to acquire,
we have not increased any of our prices.
Is this the same as customized LASIK?
The iFS laser is the first step of your iLASIK procedure. It
makes the corneal flap which allows our San Diego LASIK Surgeon to continue with the second laser which does a
customized LASIK procedure. We have now customized every part of the LASIK flap. The iFS allows us to customize
your LASIK flap in ways previous lasers could not. We make a customized diagnosis, a customized flap, and
a customized treatment.
Is microkeratome or razor blade unsafe?
No, we feel the iFS reduces the risks of traditional LASIK and
we are committed in using the safest technology. The iFS has flaps that can be up to four times stronger than
flaps made with the razor blade. Besides the safety of the flap making process, the iFS laser can make
customized flaps in terms of size and flap thickness. It can also make inverted bevel side-cut LASIK flaps which
are impossible to make with a mechanical blade.
True Custom Wavefront Technology - The Visx Star S4 Laser
with Iris Registration: A Revolution that Started 20 years ago and has been upgraded
CustomVue Technology -
The Visx laser uses wavefront technology to capture an individualized map of your eye.
This map measures the micro imperfections that LASIK surgeons
call higher order aberrations and treats them. Over 94% of patients in the FDA clinical trials are approved for
custom wavefront LASIK with the Visx Star S4 laser.
The wavescan uses a specialized device called a Hartman-Shack
aberommeter to measure over 240 individual points in your eye.
In this example below, you can see three patients with the same
prescription. With non custom LASIK, each of these patients would have received the same LASIK laser treatment.
However, with custom technology these patients have completely different wavefront maps and would receive a
unique LASIK treatment.
Iris Registration Technology - Aligning your LASIK
Iris Registration is designed to compensate for your eyes
rotation (torsion) when you lay flat.
It uses advanced intrared technology and computer technology to
compensate if your eyes are rotated.
It is the only FDA approved method that accomplishes this goal.
For surgeons using other laser systems, they have to mark your eye with a pen to make sure that your treatment
is aligned. The Iris Registration technology greatly increases the safey and accuracy of you iLASIK
iDesign Advanced Custom LASIK - Making the Best CustomVue Technology Better!
5x the Resolution:The iDESIGN system's uses a wavefront sensor
thousands of tiny sensors the diameter of a human hair. This allows over 1200 data points to be made in a 3
second scan. This is 500% more data than other CustomVue technology
Easy for Patients: The iDesign Can take up
to 5 scans in three seconds. It measures
wavefront aberrometry, wavefront refraction, corneal topography, keratometry, and pupillometry. This makes your
Treat Larger Prescriptions: The FDA has allowed
the use in patients as young as 18 and treats more than 25% more astigmatism.
Quality Outcomes: The initial
studies have shown that the majority of patients are satisfied with their quality of vision.
iDesign 2.0 Upgrade:
The iDesign 2.0 improved upon the previous technology by
incorporating topography information. Learn more here.
