The WaveLight® ALLEGRETTO WAVE® / ALLEGRETTO WAVE®
Eye-Q Excimer Laser System
Caution: Federal (USA) law restricts this device to sale by, or on the order
of, a physician.
Statements regarding the potential benefits of wavefront-guided and Wavefront Optimized®
laser-assisted
in-situ keratomileusis (LASIK) are based upon the results of clinical trials. These
results are indicative of not only the WaveLight® ALLEGRETTO WAVE®
/ ALLEGRETTO WAVE® Eye-Q Excimer Laser System treatment but also
the care of the clinical physicians, the control of the surgical environment by
those physicians, the clinical trials’ treatment parameters and the clinical trials’
patient inclusion and exclusion criteria. Although many clinical trial patients
after the wavefront-guided and Wavefront Optimized® procedure saw
20/20 or better and/or had or reported having better vision during the day and at
night, compared to their vision with glasses or contact lenses before the procedure,
individual results may vary. You can find information about the clinical trials
below and in the Procedure Manuals for the WaveLight® ALLEGRETTO
WAVE® / ALLEGRETTO WAVE® Eye-Q Excimer Laser System.
As with any surgical procedure, there are risks associated with the wavefront-guided
and Wavefront Optimized® treatment. Before treating patients with
these procedures, you should carefully review the Procedure Manuals, complete the
Physician WaveLight® System Certification Course, provide your patients
with the Patient Information Booklet, and discuss the risks associated with this
procedure and questions about the procedure with your patients.
Indications: The WaveLight® ALLEGRETTO WAVE®
/ ALLEGRETTO WAVE® Eye-Q Excimer Laser System is indicated to perform
LASIK treatments in patients with documented evidence of a stable manifest refraction
defined as less than or equal to 0.50 diopters (D) of preoperative spherical equivalent
shift over one year prior to surgery, exclusive of changes due to unmasking latent
hyperopia in patients 18 years of age or older: for the reduction or elimination
of myopic refractive errors up to -12.0 D of sphere with and without astigmatic
refractive errors up to -6.0 D; for the reduction or elimination of hyperopic refractive
errors up to +6.0 D of sphere with and without astigmatic refractive errors up to
5.0 D at the spectacle plane, with a maximum manifest refraction spherical equivalent
(MRSE) of +6.0 D; in conjunction with the WaveLight® ALLEGRO Analyzer®
device for the reduction or elimination of up to -7.0 D of spherical equivalent
myopia or myopia with astigmatism, with up to -7.0 D of spherical component and
up to 3.0 D of astigmatic component at the spectacle plane; and in patients 21 years
of age or older for the reduction or elimination of naturally occurring mixed astigmatism
of up to 6.0 D at the spectacle plane.
LASIK is an elective procedure with the alternatives including but not limited to
eyeglasses, contact lenses, photorefractive keratectomy (PRK), and other refractive
surgeries. Only practitioners who are experienced in the medical management and
surgical treatment of the cornea, who have been trained in laser refractive surgery
including laser system calibration and operation, may use the device as approved.
Prospective patients, as soon as they express an interest in an indicated LASIK
procedure and prior to undergoing surgery, must be given the WaveLight®
System Patient Information Booklet and must be informed of the alternatives for
refractive correction including eyeglasses, contact lenses, PRK, and other refractive
surgeries.
Clinical Data Myopia: The WaveLight® ALLEGRETTO WAVE®
/ ALLEGRETTO WAVE® Eye-Q Excimer Laser System was studied in clinical
trials in the United States with 901 eyes treated, of which 813 of 866 eligible
eyes were followed for 12 months. Accountability at 3 months was 93.8%, at 6 months
was 91.9%, and at 12 months was 93.9%.
The studies found that of the 844 eyes eligible for the uncorrected visual acuity
(UCVA) analysis of effectiveness at the 3-month stability time point, 98.0% were
corrected to 20/40 or better, and 84.4% were corrected to 20/20 or better without
spectacles or contact lenses.
The clinical trials showed that the following subjective patient adverse events
were reported as moderate to severe at a level at least 1% higher than baseline
of the subjects at 3 months post-treatment: visual fluctuations (12.8% at baseline
versus 28.6% at 3 months). Long term risks of LASIK for myopia with and without
astigmatism beyond 12 months have not been studied.
Clinical Data Hyperopia: The WaveLight® ALLEGRETTO WAVE®
/ ALLEGRETTO WAVE® Eye-Q Excimer Laser System has been studied in
clinical trials in the United States with 290 eyes treated, of which 100 of 290
eligible eyes were followed for 12 months. Accountability at 3 months was 95.2%,
at 6 months was 93.9%, and at 12 months was 69.9%.
The studies found that of the 212 eyes eligible for the UCVA analysis of effectiveness
at the 6-month stability time point, 95.3% were corrected to 20/40 or better, and
67.5% were corrected to 20/20 or better without spectacles or contact lenses.
The study showed that the following subjective patient adverse events were reported
as much worse by at least 1% of the subjects (in order of increasing frequency)
at 6 months post final treatment: glare from bright lights (3.0%); night driving
glare (4.2%); light sensitivity (4.9%); visual fluctuations (6.1%); and halos (6.4%).
Long term risks of LASIK for hyperopia with and without astigmatism beyond 12 months
have not been studied.
Clinical Data Mixed Astigmatism: The WaveLight® ALLEGRETTO
WAVE® / ALLEGRETTO WAVE®
Eye-Q Excimer Laser System has been studied in clinical trials in the United States
with 162 eyes treated, of which 111 were eligible to be followed at 6 months. Accountability
at 1 month was 99.4%, at 3 months was 96.0%, and at 6 months was 100.0%.
The studies found that of the 142 eyes eligible for the UCVA analysis of effectiveness
at the 3-month stability time point, 95.8% achieved acuity of 20/40 or better, and
67.6% achieved acuity of 20/20 or better without spectacles or contact lenses.
The clinical trials showed that the following subjective patient adverse events
were reported as moderate to severe at a level at least 1% higher than baseline
of the subjects at 3 months post-treatment: sensitivity to light (43.3% at baseline
versus 52.9% at 3 months); visual fluctuations (32.1% at baseline versus 43.0% at
3 months); and halos (37.0% at baseline versus 42.3% at 3 months). Long term risks
of LASIK for mixed astigmatism beyond 6 months have not been studied.
Clinical Data Wavefront-guided Treatment of Myopia: The WaveLight®
ALLEGRETTO WAVE® / ALLEGRETTO WAVE® Eye-Q Excimer
Laser System used in conjuction with the Wavelight ALLEGRETTO device was studied
in a randomized clinical trial in the United States with 374 eyes treated; 188 with
wavefront-guided LASIK (Study Cohort) and 186 with Wavefront Optimized®
LASIK (Control Cohort). 178 of the Study Cohort and 180 of the Control Cohort were
eligible to be followed at 6 months. In the Study Cohort, accountability at 1 month
was 96.8%, at 3 months was 96.8%, and at 6 months was 93.3%. In the Control Cohort,
accountability at 1 month was 94.6%, at 3 months was 94.6%, and at 6 months was
92.2%.
The studies found that of the 180 eyes eligible for the UCVA analysis of effectiveness
at the 6-month stability time point in the Study Cohort, 99.4% were corrected to
20/40 or better, and 93.4% were corrected to 20/20 or better without spectacles
or contact lenses. In the Control Cohort, of the 176 eyes eligible for the UCVA
analysis of effectiveness at the 6-month stability time point, 99.4% were corrected
to 20/40 or better, and 92.8% were corrected to 20/20 or better without spectacles
or contact lenses.
The clinical trials showed that the following subjective patient adverse events
were reported as moderate to severe at a level at least 1% higher than baseline
of the subjects at 3 months post-treatment in the Study Cohort: light sensitivity
(37.2% at baseline versus 47.8% at 3 months); and visual fluctuations (13.8% at
baseline versus 20.0% at 3 months). In the Control Cohort: halos (36.6% at baseline
versus 45.4% at 3 months); and visual fluctuations (18.3% at baseline versus 21.9%
at 3 months). Long term risks of wavefront-guided LASIK for myopia with and without
astigmatism beyond 6 months have not been studied.
Contraindications: LASIK treatments using the WaveLight® ALLEGRETTO
WAVE® / ALLEGRETTO WAVE® Eye-Q Excimer Laser System
are contraindicated if any of the following conditions exist. Potential contraindications
are not limited to those included in this list: pregnant or nursing women; patients
with a diagnosed collagen vascular, autoimmune or immunodeficiency disease; patients
with diagnosed keratoconus or any clinical pictures suggestive of keratoconus; and
patients who are taking one or both of the following medications: isotretinoin (Accutane®1),
amiodarone hydrochloride (Cordarone®2).
Warnings: Any LASIK treatment with the WaveLight® ALLEGRETTO
WAVE® / ALLEGRETTO WAVE®
Eye-Q Excimer Laser System is not recommended in patients who have: systemic diseases
likely to affect wound healing, such as connective tissue disease, insulin dependent
diabetes, severe atopic disease or an immunocompromised status; a history of Herpes
simplex or Herpes zoster keratitis; significant dry eye that is unresponsive to
treatment; severe allergies; and unreliable preoperative wavefront examination that
precludes wavefront-guided treatment. The wavefront-guided LASIK procedure requires
accurate and reliable data from the wavefront examination. Every step of every wavefront
measurement that may be used as the basis for a wavefront-guided LASIK procedure
must be validated by the user. Inaccurate or unreliable data from the wavefront
examination will lead to an inaccurate treatment.
Precautions: Safety and effectiveness of the WaveLight® ALLEGRETTO
WAVE® / ALLEGRETTO WAVE® Eye-Q Excimer Laser System
have not been established for patients with: progressive myopia, hyperopia, astigmatism
and/or mixed astigmatism; ocular disease; previous corneal or intraocular surgery,
or trauma in the ablation zone; corneal abnormalities including, but not limited
to, scars, irregular astigmatism and corneal warpage; residual corneal thickness
after ablation of less than 250 microns increasing the risk for corneal ectasia;
pupil size below 7.0 mm after mydriatics where applied for wavefront-guided ablation
planning; history of glaucoma or ocular hypertension of > 23 mmHg; taking the medication
sumatriptan succinate (Imitrex®3); under 18 years (21 years for mixed
astigmatism) of age; over the long term (more than 12 months after surgery); corneal,
lens and/or vitreous opacities including, but not limited to, cataract; iris problems
including, but not limited to, coloboma and previous iris surgery compromising proper
eyetracking; taking medications likely to affect wound healing including, but not
limited to, antimetabolites; treatments with an optical zone below 6.0 mm or above
6.5 mm in diameter; treatment targets different from emmetropia (plano) in which
the wavefront-calculated defocus (spherical term) has been adjusted; myopia greater
than – 12.0 D or astigmatism greater than 6 D; hyperopia greater than + 6.0 D or
astigmatism greater than 5.0 D; mixed astigmatism greater than + 6.0 D; and in cylinder
amounts > 4.0 to < 6.0 D.
Due to the lack of large numbers of patients in the general population, there are
few subjects with cylinder amounts in this range to be studied. Not all complications,
adverse events, and levels of effectiveness may have been determined.
Pupil sizes should be evaluated under mesopic illumination conditions. Effects of
treatment on vision under poor illumination cannot be predicted prior to surgery.
Some patients may find it more difficult to see in such conditions as very dim light,
rain, fog, snow and glare from bright lights. This has been shown to occur more
frequently in the presence of residual refractive error and perhaps in patients
with pupil sizes larger than the optical zone size.
The refraction is determined in the spectacle plane, but treated in the corneal
plane. In order to determine the right treatment program to achieve the right correction,
assessment of the vertex distance during refraction testing is recommended. Preoperative
evaluation for dry eyes should be performed. Patients should be advised of the potential
for dry eyes post LASIK and post wavefront-guided LASIK surgery. This treatment
can only be provided by a licensed healthcare professional.
Adverse Events and Complications for Myopia: Certain adverse events and complications
occurred after the LASIK surgery. Two adverse events occurred during the postoperative
period of the clinical study: 0.2% (2/876) had a lost, misplaced, or misaligned
flap reported at the 1 month examination.

treatment, corneal edema at 1 month or later visible in the slit lamp exam; any
complication leading to intraocular surgery; melting of the flap of >1 mm2;
epithelium of >1 mm2 in the interface with loss of 2 lines or more of
BSCVA; uncontrolled IOP rise with increase of >5 mmHg or any reading above 25 mmHg;
retinal detachment or retinal vascular accident; and decrease in BSCVA of >10 letters
not due to irregular astigmatism as shown by hard contact lens refraction.

Adverse Events and Complications for Mixed Astigmatism: Certain adverse events
and complications occurred after the LASIK surgery. No protocol defined adverse
events occurred during the clinical study. However, two events occurred which were
reported to the FDA as Adverse Events.
The first event involved a patient who postoperatively was subject to blunt trauma
to the treatment eye
6 days after surgery. The patient was found to have an intact globe with no rupture,
inflammation or any dislodgement of the flap. The second event involved the treatment
of an incorrect axis of astigmatism which required retreatment.

of the flap of > 1 mm2; epithelium of > 1 mm2 in the interface
with loss of 2 lines or more of BSCVA; uncontrolled IOP rise with increase of >
5 mmHg or any reading above 25 mmHg; and decrease in BSCVA of > 10 letters not due
to irregular astigmatism as shown by hard contact lens refraction.
The following complications occurred 3 months after wavefront-guided LASIK during
this clinical trial: corneal epithelial defect (0.6%); foreign body sensation (0.6%);
and pain (0.6%).
The following complications did NOT occur 3 months following wavefront-guided LASIK
in this clinical trial: corneal edema; any epithelium in the interface; ghosting
or double images; and need for lifting and/or reseating of the flap/cap.

if any of the following conditions exist. Potential contraindications are not limited to those included
in this list: pregnant or nursing women; patients with a diagnosed collagen vascular, autoimmune or
immunodeficiency disease; patients with diagnosed keratoconus or any clinical pictures suggestive of
keratoconus; and patients who are taking one or both of the following medications: isotretinoin
(Accutane®1), amiodarone hydrochloride (Cordarone®2).
Warnings: Any LASIK treatment with the WaveLight® ALLEGRETTO
WAVE® / ALLEGRETTO WAVE® Eye-Q Excimer Laser System is not recommended
in patients who have: systemic diseases likely to affect wound healing, such as connective tissue disease,
insulin dependent diabetes, severe atopic disease or an immunocompromised status; a history of Herpes simplex

Precautions: Safety and effectiveness of the WaveLight® ALLEGRETTO
WAVE® / ALLEGRETTO WAVE® Eye-Q Excimer Laser System have not been
established for patients with: progressive myopia, hyperopia, astigmatism and/or mixed astigmatism;
ocular disease; previous corneal or intraocular surgery, or trauma in the ablation zone; corneal
abnormalities including, but not limited to, scars, irregular astigmatism and corneal warpage; residual
corneal thickness after ablation of less than 250 microns increasing the risk for corneal ectasia; pupil
size below 7.0 mm after mydriatics where applied for wavefront-guided ablation planning; history of glaucoma
or ocular hypertension of > 23 mmHg; taking the medication sumatriptan succinate (Imitrex®3);
under 18 years (21 years for mixed astigmatism) of age; over the long term (more than 12 months after surgery);
corneal, lens and/or vitreous opacities including, but not limited to, cataract; iris problems including, but
not limited to, coloboma and previous iris surgery compromising proper eyetracking; taking medications likely
to affect wound healing including, but not limited to, antimetabolites; treatments with an optical zone below
6.0 mm or above 6.5 mm in diameter; treatment targets different from emmetropia (plano) in which the
wavefront-calculated defocus (spherical term) has been adjusted; myopia greater than – 12.0 D or astigmatism
greater than 6 D; hyperopia greater than + 6.0 D or astigmatism greater than 5.0 D; mixed astigmatism greater
than + 6.0 D; and in cylinder amounts > 4.0 to < 6.0 D.
Due to the lack of large numbers of patients in the general population, there are few subjects with cylinder
amounts in this range to be studied. Not all complications, adverse events, and levels of effectiveness may
have been determined.
Pupil sizes should be evaluated under mesopic illumination conditions. Effects of treatment on vision under
poor illumination cannot be predicted prior to surgery. Some patients may find it more difficult to see in
such conditions as very dim light, rain, fog, snow and glare from bright lights. This has been shown to occur
more frequently in the presence of residual refractive error and perhaps in patients with pupil sizes larger
than the optical zone size.
The refraction is determined in the spectacle plane, but treated in the corneal plane. In order to determine
the right treatment program to achieve the right correction, assessment of the vertex distance during
refraction testing is recommended. Preoperative evaluation for dry eyes should be performed. Patients should
be advised of the potential for dry eyes post LASIK and post wavefront-guided LASIK surgery. This treatment
can only be provided by a licensed healthcare professional.
Adverse Events and Complications for Myopia: Certain adverse events and complications
occurred after the LASIK surgery. Two adverse events occurred during the postoperative period of the
clinical study: 0.2% (2/876) had a lost, misplaced, or misaligned flap reported at the 1 month examination.
The following adverse events did NOT occur: corneal infiltrate or ulcer requiring treatment, corneal
edema at 1 month or later visible in the slit lamp exam; any complication leading to intraocular surgery;
melting of the flap of >1 mm2; epithelium of >1 mm2 in the interface with loss of 2
lines or more of BSCVA; uncontrolled IOP rise with increase of >5 mmHg or any reading above 25 mmHg;
retinal detachment or retinal vascular accident; and decrease in BSCVA of >10 letters not due to irregular
astigmatism as shown by hard contact lens refraction.
The following complications occurred 3 months after LASIK during this clinical trial: 0.8% (7/844) of eyes
had a corneal epithelial defect; 0.1% (1/844) had any epithelium in the interface; 0.1% (1/844) had foreign
body sensation; 0.2% (2/844) had pain; and 0.7% (6/844) had ghosting or double images in the operative eye.
The following complications did NOT occur 3 months following LASIK in this clinical trial: corneal edema
and need for lifting and/or reseating the flap/cap.
Adverse Events and Complications for Hyperopia: Certain adverse events and complications
occurred after the LASIK surgery. Only one adverse event occurred during the clinical study: one eye (0.4%)
had a retinal detachment or retinal vascular accident reported at the 3 month examination.

foreign body sensation; pain, ghosting or double images; and need for lifting and/or reseating of the flap/cap.
Adverse Events and Complications for Mixed Astigmatism: Certain adverse events and
complications occurred after the LASIK surgery. No protocol defined adverse events occurred during the
clinical study. However, two events occurred which were reported to the FDA as Adverse Events.
The first event involved a patient who postoperatively was subject to blunt trauma to the treatment eye 6
days after surgery. The patient was found to have an intact globe with no rupture, inflammation or any
dislodgement of the flap. The second event involved the treatment of an incorrect axis of astigmatism
which required retreatment.
The following adverse events did NOT occur: corneal infiltrate or ulcer requiring treatment; corneal
epithelial defect involving the keratectomy at 1 month or later; corneal edema at 1 month or later visible
in the slit lamp exam; epithelium of > 1 mm2 in the interface with loss of 2 lines or more of
BSCVA; lost, misplaced, or misaligned flap, or any flap/cap problems requiring surgical intervention beyond
1 month; decrease in BSCVA of > 10 letters not due to irregular astigmatism as shown by hard contact lens
refraction; any complication leading to intraocular surgery; melting of the flap of > 1 mm2;
uncontrolled IOP rise and retinal detachment or retinal vascular accident.
None of the following complications occurred at 3 months after LASIK during this clinical trial: corneal
edema; corneal epithelial defect; any epithelium in the interface; foreign body sensation, pain, ghosting
or double images; and need for lifting and/or reseating of the flap/cap.
Subjects were asked to complete a patient questionnaire preoperatively and at 3-months, 6-months, and 1-year
postoperatively.
Adverse Events and Complications for Wavefront - guided Myopia: Certain adverse events
and complications occurred after the wavefront-guided LASIK surgery. No adverse event occurred during
wavefront-guided treatments during this clinical study.
The following adverse events did NOT occur: corneal infiltrate or ulcer requiring treatment; lost, misplaced
or misaligned flap or any flap/cap problems requiring surgical intervention beyond 1 month; corneal edema
at 1 month or later visible in the slit lamp exam; any complication leading to intraocular surgery; melting
of the flap of > 1 mm2; epithelium of > 1 mm2 in the interface with loss of 2 lines
or more of BSCVA; uncontrolled IOP rise with increase of > 5 mmHg or any reading above 25 mmHg; and decrease
in BSCVA of > 10 letters not due to irregular astigmatism as shown by hard contact lens refraction.
The following complications occurred 3 months after wavefront-guided LASIK during this clinical trial: corneal
epithelial defect (0.6%); foreign body sensation (0.6%); and pain (0.6%).
The following complications did NOT occur 3 months following wavefront-guided LASIK in this clinical trial:
corneal edema; any epithelium in the interface; ghosting or double images; and need for lifting and/or
reseating of the flap/cap.
ATTENTION: The safety and effectiveness of LASIK surgery has ONLY been established with
an optical zone of 6.0—6.5 mm and an ablation zone of 9.0 mm.

WaveLight® FS200 Femtosecond Laser System
The WaveLight® FS200 Laser System
Federal (USA) law restricts this device to sale by, or on the order of, a physician.
As with any surgical procedure, there are risks associated with the use of the WaveLight®
FS200 Femtosecond Laser System. Before treating patients with this device, you should
carefully review the Procedure Manual, complete the Physician WaveLight®
System Certification Course, and discuss the risks associated with this procedure
and questions about the procedure with your patients.
Indications: The WaveLight® FS200 Laser System is indicated
for use in the creation of a corneal flap in patients undergoing LASIK surgery or
other surgery or treatment requiring initial lamellar resection of the cornea; in
patients undergoing surgery or other treatment requiring initial lamellar resection
of the cornea to create tunnels for placement of corneal ring segments; in the creation
of a lamellar cut/resection of the cornea for lamellar keratoplasty; and in the
creation of a penetrating cut/incision for penetrating keratoplasty and for corneal
harvesting.
The WaveLight® FS200 delivery system is used in conjunction with
a sterile disposable Patient Interface, consisting of pre-sterilized suction ring
assemblies and pre-sterilized applanation cones, intended for single use.
The WaveLight® FS200 Laser System should only be operated by, or
under the direct supervision of, a trained physician with certification in laser
safety and in the use of the WaveLight® FS200 Laser.
Contraindications: LASIK treatments are contraindicated in: Pregnant or nursing
women; patients with a diagnosed collagen vascular, autoimmune or immunodeficiency
disease; and patients who are taking one or both of the following medications: isotretinoin
(Accutane®1), amiodarone hydrochloride (Cordarone®2).
Flap Contraindications: Lamellar resection for the creation of a corneal
flap using the WaveLight® FS200 laser is contraindicated if any of
the following conditions exist. Potential contraindications are not limited to those
included in this list: corneal edema; corneal lesions; hypotony; glaucoma; existing
corneal implant; and keratoconus.
Keratoplasty Contraindications: Penetrating cut/incision (for penetrating
keratoplasty) is contraindicated in: any corneal opacity adequately dense to obscure
visualization of the iris; descemetocoete with impending corneal rupture; previous
corneal incisions that might provide a potential space into which the gas produced
by the procedure can escape; and corneal thickness requirements that are beyond
the range of the System.
Other Considerations: The following conditions should also be considered:
severe corneal thinning; subjects with pre-existing glaucoma; a history of steroid
responsive rise in intraocular pressure; preoperative intraocular pressure greater
than 21 mmHg in the operative eye; subjects with more than 1000 μm corneal thickness
at the 9 mm peripheral zone; active intraocular inflammation; and active ocular
infection.
Complications: Possible complications which may result from flap cutting
include (potential complications are not limited to those included in this list):
corneal edema; corneal pain; epithelial ingrowth; epithelial infection; flap de-centration;
incomplete flap creation; flap tearing or incomplete lift-off; free cap; photophobia;
corneal inflammation, such as diffuse lamellar keratitis (DLK), corneal infiltrates
and iritis; thin- or thick flaps; flap striae; and corneal ectasia (secondary keratoconus).
Warnings: Any treatment with the WaveLight® FS200 is not recommended
in patients who have: systemic diseases likely to affect wound healing, such as
connective tissue disease, insulin dependent diabetes, severe atopic disease or
an immunocompromised status; a history of Herpes simplex or Herpes zoster keratitis;
significant dry eye that is unresponsive to treatment; severe allergies; and a history
of glaucoma or ocular hypertension.
We recommend discussing the following potential complications of this device with
your patients:
Transient Light Sensitivity Syndrome (TLSS): Transient Light Sensitivity
Syndrome is characterized by symptoms of mild to severe light sensitivity which
manifests between two and six weeks postoperatively. Patients experience no decrease
in uncorrected or best spectacle-corrected visual acuity. The incidence of this
sensitivity was observed in approximately 1% of patients who undergo flap creation
with a femtosecond laser.3 Patients respond to the use of hourly topical
steroids such as Pred Forte (Allergan), and most report improvement within one week
of treatment.
Peripheral Light Spectrum (PLS): Peripheral Light Spectrum is a temporary
phenomenon whereby patients report the perception of a spoke-like spectrum of light
in the periphery of their vision. PLS has no clinical examination findings and no
effect on visual acuity; however the potential diffractive effects may be bothersome
to some patients. Reported in only a small amount of cases, the onset of symptoms
occurs during the immediate postoperative period, and typically resolves within
three months but may be slightly persistent in rare cases. The visual impact of
PLS is clinically inconsequential for the vast majority of patients.
