Cataract Surgery: A Look Ahead
Paul C. Ajamian, O.D.
![Page 2: Cataract Surgery: A Look Ahead - Aventri · • The size, shape, and positioning of the capsulorhexis is a key determinant for effective lens position¹ • A 0.5mm axial plane deviation](https://reader034.vdocument.in/reader034/viewer/2022051408/5ffb647467179f337b00b3d2/html5/thumbnails/2.jpg)
Don’t forget the days when all we could do was to send
cataracts out! • Mechanism developed to pay OD’s
for post-op care rendered
• Make sure patient knows of any co-management arrangement and agrees to it willingly
![Page 3: Cataract Surgery: A Look Ahead - Aventri · • The size, shape, and positioning of the capsulorhexis is a key determinant for effective lens position¹ • A 0.5mm axial plane deviation](https://reader034.vdocument.in/reader034/viewer/2022051408/5ffb647467179f337b00b3d2/html5/thumbnails/3.jpg)
Component 1: History
• Eye: functional history such as “problems with glare/TV/driving at night” – Activities of Daily Living: MUST BE DOCUMENTED!
• Social History: ?chronic depression, bipolar, anxiety disorders
• Observation during exam: ambivalence, excessive questioning, unrealistic expectations, wanting guarantees
![Page 4: Cataract Surgery: A Look Ahead - Aventri · • The size, shape, and positioning of the capsulorhexis is a key determinant for effective lens position¹ • A 0.5mm axial plane deviation](https://reader034.vdocument.in/reader034/viewer/2022051408/5ffb647467179f337b00b3d2/html5/thumbnails/4.jpg)
Past Eye and Medical History Critical
• Medications: Flomax?
• Contact Lens Wearer?
• Prednisone (PSC)
• Trauma
• Family history of cataracts at a young age
• Diabetes/Hypertension
– How long have you had it
– What do you take for it
– Is it under control/when last checked
– Doctor’s name
![Page 5: Cataract Surgery: A Look Ahead - Aventri · • The size, shape, and positioning of the capsulorhexis is a key determinant for effective lens position¹ • A 0.5mm axial plane deviation](https://reader034.vdocument.in/reader034/viewer/2022051408/5ffb647467179f337b00b3d2/html5/thumbnails/5.jpg)
Component 2: Vision and Refraction
• Visual Acuity (D & N)
• Pinhole should be part of vision
– Monocular diplopia or glare alleviated?
• Glare testing or BAT (medium setting), or “Ambient Light” (room lights on)
for any patient who is 20/40 or better
![Page 6: Cataract Surgery: A Look Ahead - Aventri · • The size, shape, and positioning of the capsulorhexis is a key determinant for effective lens position¹ • A 0.5mm axial plane deviation](https://reader034.vdocument.in/reader034/viewer/2022051408/5ffb647467179f337b00b3d2/html5/thumbnails/6.jpg)
Time to Write Down Your Impression and Plan
• Impression:– “Cataracts OD > OS with difficulty reading OU– 2+ NS consistent with reduced VA– Would like to rely less on glasses
• Plan:– Schedule bilateral Restor IOL’s OD then OS
• Premium IOL discussed, patient not interested/Schedule conventional monofocal IOL OD then OS
![Page 7: Cataract Surgery: A Look Ahead - Aventri · • The size, shape, and positioning of the capsulorhexis is a key determinant for effective lens position¹ • A 0.5mm axial plane deviation](https://reader034.vdocument.in/reader034/viewer/2022051408/5ffb647467179f337b00b3d2/html5/thumbnails/7.jpg)
Or………..
• Impression:– “Cataracts OU, night driving problems – 3+ NS consistent with reduced VA– 2 diopters of cylinder
• Plan:– IOL’s OD then OS– Patient denies Toric
![Page 8: Cataract Surgery: A Look Ahead - Aventri · • The size, shape, and positioning of the capsulorhexis is a key determinant for effective lens position¹ • A 0.5mm axial plane deviation](https://reader034.vdocument.in/reader034/viewer/2022051408/5ffb647467179f337b00b3d2/html5/thumbnails/8.jpg)
Communication Key!
• Communicate pertinent findings directly to surgeon…don’t leave it to chance!– Meds (Flomax) and
Conditions (Pseudoexfoliation Syndrome, Glaucoma) Ocular Surface Disease
– Visit the surgeon so you know what patients will experience

Limbal Relaxing Incisions
Traditional, Handheld Diamond Knife
• Manually executed by “tracing”
corneal marks
• Inconsistent depth control
• Unpredictable effect due to
imprecise wound architecture
and depth

Intra-stromal vs. Penetrating Astigmatic Keratotomy
• Less invasive
• No epithelial injury
• Quick procedure
• Fast visual recovery
• Minimize loss of corneal sensation
• Preserve ability to create a flap later

What does the future hold?
• Femtosecond cataract lasers exist in 34 countries– Each with their own financial and regulatory
framework.
• Just as femtoLASIK coexists with mechanical microkeratomes, so does LACS coexist with manual surgery. There is a place for both, but the more precise and expensive technology will eventually dominate.

Believe in the Technology
• Go watch a case
• Truly understand the implications of
– Safer
– Better Refractive outcomes
• What does that mean for your patients and how does that reflect your practice

Fee Discussion• Hearing fees from you validates
• Mentioning fee does not make you a salesperson
• Should not put you on the defensive
• The fee is the fee. Need not apologize.
• Added value costs extra
• “We offer financing”
![Page 28: Cataract Surgery: A Look Ahead - Aventri · • The size, shape, and positioning of the capsulorhexis is a key determinant for effective lens position¹ • A 0.5mm axial plane deviation](https://reader034.vdocument.in/reader034/viewer/2022051408/5ffb647467179f337b00b3d2/html5/thumbnails/28.jpg)

IOL discussion and selection• The “old days” of
sending the patient on to your surgeon and not thinking about the refractive result are over
• You know more about their refractive history than anyone else, so be involved and stay involved

“Continuous Vision”
• Do you dream of freedom from reading glasses and bifocals? Continuous Vision from XYZ Eye Associates may be right for you. Our goal is and has always been to provide all of our patients with their most optimal vision possible, regardless of their age and eye condition.
![Page 32: Cataract Surgery: A Look Ahead - Aventri · • The size, shape, and positioning of the capsulorhexis is a key determinant for effective lens position¹ • A 0.5mm axial plane deviation](https://reader034.vdocument.in/reader034/viewer/2022051408/5ffb647467179f337b00b3d2/html5/thumbnails/32.jpg)
• Specially developed to provide blended, functional vision at all distances, Continuous Vision may be the best option for many cataract patients and individuals with poor reading vision who wish to leave their glasses (and money) behind
• The difference between Monovision and Continuous Vision =

Patient Resources
• Website
• Brochures
• Surgeon should get everyone to sign something that says they were given all options
![Page 44: Cataract Surgery: A Look Ahead - Aventri · • The size, shape, and positioning of the capsulorhexis is a key determinant for effective lens position¹ • A 0.5mm axial plane deviation](https://reader034.vdocument.in/reader034/viewer/2022051408/5ffb647467179f337b00b3d2/html5/thumbnails/44.jpg)

Malpractice?
• “Will I be at risk if I tell the patient about the lens and they end up not doing well”
• ODs are at a higher risk from “failure to inform” suits than from misdiagnosis suits

Using the Right Terminology
• Premium lens
• Lifestyle lens
• High Technology Lens
• Multifocal lens

Good Candidates?
• Cataract patient presents with one pseudophakic eye (monofocal lens) and a cataract in the other eye, or a cataract in one eye only
• Patient presents with s/p lasik ou, now has cataracts ou
• Patient has >2 diopters of cylinder

The Money Talk
– Don’t apologize for the cost of the ReSTOR surgery over typical cataract surgery
– It is more valuable, an advance in technology, and requires more on the part of the surgeon and the co-managing doctor of optometry

Save Yourself Some Time
– I mention the cost early on to save a lot of unnecessary discussion
– Document in chart that you offered it and patient declined

Post Op Visits• CDE on Alcon Infiniti
• “Cumulative Dispersed Energy” = average U/S power ×U/S time
• Should be under 5 for most skilled surgeons
• If over, look for corneal folds/edema
• Ask your surgeon to inform you of abnormal CDE’s

Post-Op Considerations• These patients are very
sensitive to visual changes, so pay attention to the retina and attend to the ocular surface
![Page 65: Cataract Surgery: A Look Ahead - Aventri · • The size, shape, and positioning of the capsulorhexis is a key determinant for effective lens position¹ • A 0.5mm axial plane deviation](https://reader034.vdocument.in/reader034/viewer/2022051408/5ffb647467179f337b00b3d2/html5/thumbnails/65.jpg)
PCO• Our experience: These
patients are more sensitive to it.
• Thus….YAG laser capsulotomy earlier than monofocal lenses although best to wait 3 months for insurance purposes
