iDesign - Advanced Custom iLASIK
iDesign - San Diego's Newest Advanced Custom Wavefront System Upgrade
iDesign Advanced Wavescan System - Smart and Powerful LASIK powered by NASA like techonology.
LASIK powered by iDesign has made your
procedure smarter and better. iDesign
incorporates custom wavefront technology similar to that used in NASA telescopes. In custom LASIK, a special
device called a wavescan maps out your optical system to measure your detailed prescription and give us advanced
information (higher order aberrations) about your eyes. This wavescan is then used to complete a
completely custom laser treatment of your eyes.
iDesign takes an already innovative technology and improves it by
giving it 5x the definition of previous wavescan technology. It also gives us additional information about your
eyes through advanced corneal imaging. It works like a computer "brain" and it captures more data than ever
before to get a detailed map of your eye's unique imperfections to accurately create a treatment.
How does iDesign work?
iDesign system is smart technology that creates a unique and personalized map of your eye.
It accomplishes this by shining a light into your eye. As the light travels through the eye, it passes
the cornea, lens, and vitreous humor. The light then travels back to the device and through an advanced imaging
device called a Hartmann-Shack aberrometer. This information is then compared to the behavior of light
passing through an ideal eye with no nearsightedness, astigmatism, or imperfections. By looking at the
differences between a perfect eye and your eye, a detailed map of your eye is made. Just like a fingerprint, no
two wavescans are exactly alike.

Institute's Actual iDesign Device
Key Advantages Over Previous LASIK Technology:
5X The Resolution!
- High definition Hartmann-Shack sensor with 5x the resolution versus the WaveScan system
- 1257 micro refractions over a 7 mm pupil)
- Larger wavefront measurement, up to 8.5 mm
- This increased resolution allows us to capture more points to create a more detailed and customized map of your
- The measurements are up to 25X the resolution that is normally used when you get measured for glasses and
- Increasing resolution enables:
- Potential to capture more eyes
- Improved spot quality, reduces spot cross over
- Greater detection of HOAs
- Enhanced reconstruction precision
The images compare the iDesign's resolution to a traditional
custom wavescan. The iDesign is able to capture more refractions (measurements). The two devices are
imaging a key placed over an artificial eye. This helps to allow for more accurate mapping of the key. The
iDesign allows for a more accurate mapping of the key.
Unfortunately, the iDesign is not approved for all patients or
prescriptions. Our LASIK surgeon (Dr. Pham) or our center optometrist (Dr. Darrow) will be happy to discuss with
you which technology (CustomVue or iDesign) is best and FDA approved for your prescription.
The San Diego LASIK Institute iDesign can treat LARGER
prescriptions and Higher levels of astigmatism:
iDesign's High Quality of Vision and
Image Caption: At 6 months after surgery, nearsighted patients in a clinical study reported the
following: 97% were satisfied with their vision, majority of people acheived 20/16 vor better vision, 99%
were not limited in active sports or outdoor activities, 99% had little or no difficulty with the clarity of
their vision, and 93% had little to no difficulty driving at night.

What types of measurements can the iDesign get in 3
iDESIGN system is a powerful tool that can capture a lot of information
about your eyes. The iDesign Measures:
• Wavefront refraction - This measures your prescription.
The newer iDesign has 5x the resolution of traditional CustomVue wavescan LASIK.
Wavefront aberrometry - This measures complicated
imperfections of your eyes. These "higher order aberrations" are then treated with the laser.
• Keratometry - This measures the steepness or
curvature of the cornea. It also automatically incorporates it into your LASIK treatment to make the LASIK
Corneal topography – This is a map that is used to help screen for corneal diseases
• Pupillometry - This measures pupil diameter under controlled cark
(scotopic) and bright (photopic) lighting conditions.
The iDesign is able to improve iris registration by taking more
high-quality measurements. Iris registration uses your iris' unique landmarks to compensate for your eye's
rotation when you are laying down.
Indications and Important Safety Information
ATTENTION: Reference the Directions for Use for a complete listing of Indications and Important Safety
INDICATIONS: The STAR S4 IR® Excimer Laser System and iDESIGN® Advanced WaveScan
Studio System is indicated for wavefront‑guided laser assisted in situ keratomileusis (LASIK) in
patients with myopia as measured iDESIGN® System up to -11.00 D spherical equivalent, with up
-5.00 D cylinder; with agreement between manifest refraction (adjusted for optical infinity)
and iDESIGN® System refraction of 1) spherical equivalent: magnitude of the difference is less
than 0.625 D, and 2) cylinder: magnitude of the difference is less than or equal to 0.5 D; with patients 18 years of
age or older, and with refractive stability (a change of ≤1.0 D in sphere or cylinder for a minimum of
12 months prior to surgery).
CONTRAINDICATIONS: Laser refractive surgery is contraindicated in patients with a) collagen vascular,
autoimmune, or immunodeficiency diseases; b) pregnant or nursing women; c) keratoconus, abnormal corneal
topography, epithelial basement membrane disease (EBMD) and degenerations of the structure of the cornea; d)
symptoms of significant dry eyes; e) corneal thickness would cause anticipated treatment would violate the posterior
250 microns (μm) of corneal stroma; f) advanced glaucoma; and g) uncontrolled diabetes. If the patients
have severely dry eyes, LASIK may increase the dryness. This may or may not go away. Severe eye dryness
may delay healing of the flap or interfere with the surface of the eye after surgery. It may result in poor
vision after LASIK.
WARNINGS AND PRECAUTIONS: LASIK is not recommended in patients who: a) have a history of Herpes simplex or
Herpes zoster keratitis, b) have severe allergies or tendency rub their eyes often, c) are taking the
medication Isotretinoin (Accutane), d) are taking antimetabolites for any medical conditions.
The safety and effectiveness of this laser for LASIK correction have NOT been established in patients: a)
with progressive refractive errors; previous corneal or intraocular surgery; or trauma in the ablation zone, b) who
are taking the medication Sumatriptan (Imitrex) or Amiodaronehydrochloride (Cordarone), c) with
corneal neovascularization within 1.0 mm of the ablation zone, d) over the long term (more than 1 year after
surgery), e) for patients who engage in activities that could endanger or damage the LASIK flap, f) for patients who
have a family history of degenerative corneal disease, g) history of inflammation of eye, h) for patients who have a
history of crossed eyes (strabismus) or who have undergone strabismus surgery, i) prior LASIK or Refractive Surgery,
j) with history of any eye diseases or abnormalities such as: corneal scars or active disease, k) whose BSCVA is
worse than 20/20.
To reduce the risk of corneal ectasia, the posterior 250 microns (μm) of corneal stroma should
not be violated. The treatment of highly myopic eyes necessitates the removal of significant amounts of corneal
tissue. The iDESIGN® System calculates the estimated residual bed depth using
thepachymetry and intended flap thickness entered by the user. Actual flap thicknesses may vary. If the
estimated residual stromal bed is ≤ 320 microns, an in-the-bed pachymetric measurement should
ADVERSE EVENTS: Possible adverse events include loss of best spectacle corrected visual acuity (BSCVA),
serious Transient Light Sensitivity Syndrome, serious primary open angle glaucoma, miscreated flap,
melting of the flap, severe glare, and severe dry eyes. Complications can include corneal edema, epithelial
ingrowth, diffuse lamellar keratitis, foreign body sensation, and pain.
CAUTION: 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.
