Cataract Management
• Visual Acuity 20/50 ?
• Glare and Lifestyle
• Is your patient young and wants refractive Cataract surgery
• Or is your patient health conscious and wants no risk
• What is Binocular vision
• How is their night vision and how often do they drive at night
The Future of Cataract Management by Optometry
• Know the Lens options
• Know the Patient
• Match Options to Patient
• Financial
• Medical
• Optical
The Future of Cataract Management by Optometry
• Earlier Referrals • Loftier Expectations • More Active Role In Pre-Operative Counseling • More active Role In Choosing Procedure • More Important Than Ever In Assuring Positive Outcomes • Changing Post-Op Role • Different “Co-management” Reimbursement Model
The Future of Cataract Management by Optometry
• Understand the fee structure of each modality
• Develop a personal fee structure
• There is no 20% rule In fact the majority of the examination and patient guidance is your responsibility and should be compensated
• There is very little difference in time and expertise to implant a SV, toric, or multifocal. In fact the majority of time spent is pre and Post surgery
Cataracts In The Year 2018
•Changing Paradigm
• Earlier Diagnosis
• Earlier Surgery
• Loftier Expectations
• Harder To Manage ??

Not All Cataracts Are Created Equal
• VA is no longer the only criteria for recommending surgery
• Glare
• Contrast Sensitivity
• Night Vision Difficulties
Not All Cataract Surgeries Are Created Equal
• What Does The Patient want (expect)?
• Spectacle independence?
• No specs for sports?
• No reading glasses?
• No responsibility?
Not All Cataract Surgeries Are Created Equal
• What Do The Doctors Want (Expect)?
• Surgeon vs Referring Doctor
• Setting Realistic Expectations Is The Key!!!!!
Cataract Surgery – Choosing The “Right One”
• So Many Choices – So Little Time
• Clear Cornea vs Femtosecond
• Astigmatic Keratotomy vs Toric IOL
• Single Vision vs Multifocal
• Multifocal vs Accomodating IOL
• What About Monovision????
• And What Is Extended Depth of Focus!!!???***
Why Use A Femtosecond Laser ?
• Precise Incision Control
• Managing Astigmatism
• More Precise Capsulorhexis
• More Predictable refractive outcome
• But Is It worth the Extra Cost????
Managing Astigmatism
• Limbal Relaxing Incision
• Astigmatic keratotomy (laser guided)
• Toric IOL
• The choice depends upon amount of pre-operative astigmatism
• (And the amount of money the patient chooses to spend!!!)

The TECNIS Symfony® IOL has unique optics, creating a different visual experience
27
The proprietary echelette design introduces a novel pattern of light diffraction that elongates the
focus of the eye1
The echelette is the relief or profile of the lens (height differential) within each ring
The height, spacing, and profile of the echelettes to create a diffractive pattern for an elongated
focus

Extended Depth of Focus IOL
PP2016CT1738
• The power of the eye is wavelength
dependent. Colors that are out-of-focus
cause blur and reduce contrast.
• The phakic eye has approximately 1.38 D
of chromatic aberration between 450 and
700 nm1. Pseudophakic eyes have
between 1.45 and 2 D of chromatic
aberration, depending on the dispersion of
the IOL material2,3

Results in Contrast Enhancement
• Achromat technology for the correction of longitudinal chromatic aberration (LCA) causes contrast enhancement.
• Correction of corneal chromatic aberration results in a sharper focus of light. When combined with correction of spherical aberration, it increases retinal image quality, without negatively affecting depth of focus.1,2
• The benefits of chromatic aberration correction are pupil-size independent1

• The proprietary achromatic technology of
TECNIS Symfony® IOL not only reduces
chromatic aberration but actually corrects
chromatic aberration of the cornea.1
• Tecnis Symfony® IOL corrects chromatic
aberration to deliver a sharp image over the
entire range of vision2

Continuous Vision
TECNIS Symfony® IOL provides continuous, high-quality vision at all distances
1. TECNIS® Symfony® IOL DFU
TECNIS Symfony® IOL delivers:
• Sustained mean visual acuity of 20/25
or better through 1.5 D of defocus
• Increase of 1.0 D range of vision
throughout the defocus curve
compared to a monofocal
1. TECNIS® Symfony® IOL DFU
Excellent Vision at All Distances1
Monocular Distance Corrected vision with TECNIS Symfony® IOL improved 2.4 lines for
intermediate vision and 2.2 lines for near vision compared to the monofocal control.1
1. TECNIS® Symfony® IOL DFU
Less than 3% of patients spontaneously reported incidence of severe night vision symptoms
Low Incidence of Halo and Glare
WARNING: Some visual effects associated with the TECNIS® Symfony IOL may be expected due to the lens design that delivers elongation of focus. These may include a perception of halos, glare, or starbursts around lights under nighttime conditions. The experience of these phenomena will be bothersome or very bothersome in some people, particularly in low-illumination conditions. On rare occasions, these visual effects may be
significant enough that the patient may request removal of the IOL.
*Although the questionnaire was not determined to be a psychometrically
valid assessment of the concept of spectacle independence, data showed
that the Symfony IOL achieved the secondary effectiveness endpoint of
reduced overall spectacle wear compared to the control monofocal IOL

Patient Discussions
• Explain “Extended range of vision” to them
Expectation Setting Conversations
• There is no perfect lens
• Distance to computer vision, ability to read a menu
• Expect to need reading glasses for small print
• If they don’t use reading glasses it’s a bonus
• They will likely need prescription RX for some time of the day, for some specific tasks
• Day one expect slightly blurry vision,
• Vision will improve once second eye is done
• You may notice “starbursts” around light sources more noticeable at night
Preoperative considerations
Patient selection
Manage expectations
–Halos/starbursts
–Dependence on spectacles
– “No perfect lOL”
–Under-promise and over-deliver!

• Health and Wellness Philosophy of practice
Ocular Surface Wellness: The Opportunity
• Active maintenance of the Ocular Surface health supports patients’ long-term
– Vision quality – Healthy-looking eyes
– Ocular comfort – Successful Cataract surgery
– Cataract surgery can change the tear film dynamics and the ocular surface
46
Our Role in Optimizing Outcomes
When needed, pre-treat the ocular surface
Why prepare the ocular surface?
Better topography images/Improved Biometry (better K’s)
Potential for reduced risk of infection/less corneal staining
More comfortable patient
Faster healing

Optimizing Vision
• Efforts to prevent or slow OS pathology help preserve vision
• Tear film irregularity can affect retinal image quality16
• DE patients experience
– Reduced contrast sensitivity17
– Fluctuating vision
– Impact on ease of daily activities (eg, reading,
computer, driving, TV)18
– Discomfort after Cataract Surgery
49
Optimizing Vision for
Ocular Surgery Candidates
• Refractive and cataract surgery patients have high expectations for postop comfort and vision
• Visual outcomes (and postop comfort) influenced by preop OS conditions25-29
• It is our responsibility to prepare our
patients for surgery

Threats to Ocular Surface Wellness: Dry Eye and Blepharitis
• DE and blepharitis among the most common conditions eye physicians encounter43,44
– Using a very restrictive definition, DE affects nearly 5 million Americans aged 50 and older44
– Eye care practitioners may see blepharitis in ~40% of patients45

Threats to Ocular Surface Wellness: Dry Eye and Blepharitis
57
• Blepharitis comprises a number of inflammatory eyelid conditions and comorbidities46
– Dry eye
– Chalazion
– Hordeolum
– Conjunctivitis
– Keratopathy
• MGD (a form of blepharitis) may be the most common cause of evaporative

Discussion Questions How do you communicate to patients the value of a premium IOL?
What are the most common challenges you face with patient conversion and how do you address?
When speaking to patients what are the indicators you look for that give you confidence the patient is a good candidate?
PP2015CT0370

What Is The Proper Co-Management Arrangement?
• Post – Op visit – Day 1 or Week 1?
• Co-Management Codes – 66984-55
• Premium Services Upcharge -
Explain Neuroadaptation
EDOF is a DIFFERENT kind of lens
• The brain needs to get used to the extended depth of focus optics
− Help patient understand how EDOF technology works
• Emphasize that the goal is to achieve QUALITY of vision
• Explain that there’s always a trade-off
− “You may continue to need reading glasses on occasion, but you will have a greater range of vision”
• PREPARE the patient not to expect vision to be perfect at Day 1
Post-Op Considerations
• Similar to post-op care of “standard” cataract extraction
• Topical antibiotic, NSAID and steroid
• 1 Day, 1 Week, 3 Weeks, 3 Months
• The Biggest Challenge Is Managing Patient Expectations
• Reinforce Neuroadaptation
• Reinforce need for Prescription Eyeglasses
• Reinforce the Concept Of High Quality Vision
• What Is The Biggest Post-Operative Complication For These Patients?
Good Perioperative Management Relationships Are Built on Mutual Respect
• Communicate up front/define roles and expectations
• Select surgeons whose philosophies match your own
• Communicate your knowledge of the patient to the MD
• Visit the OR and schedule regular conversations
• Trade cell phone numbers; you need to be able to reach each other at any time
• Share all Pre-Op and Post-Op findings
More Discussion Questions
•Why aren’t these new technologies being embraced by OD’s?
•How do you handle the co-management fee and “upcharges”?
•What techniques can we employ to increase utilization of Premium IOLs?
