Cataract Surgery is becoming more of a Vision Correction Procedure • Patient’s have very high expectations – Rapid Visual Recovery • Minimize amount of corneal swelling on Postop Day 1
– Avoid CME with prophylactic meds – Prevention of Ocular Surface Disease • Very common in cataract surgery patients
• Patients also expect to be on target with good uncorrected vision regardless of IOL choice

Femto-cataract Surgery • What platforms are you using • What steps of the procedure are you using femto for?
If insurance was not an issue when would you recommend femto cataract surgery?

Clear Corneal Incision Neda Shamie • “…there are multiple factors for reducing endophthalmitis and that incision construction and architecture are the primary factors in preventing post-op endophthalmitis” – Howard Fine, MD
The ideal clear corneal incision • Self-sealing & watertight – wound architecture
• Astigmatically neutral – size and limbal position
• Easily accessible – placement and ease of opening
• Challenges with laser assisted CC wounds? • Thoughts as to why? • Solutions?

Waring IV, GO
Cortex Removal with Femtosecond Laser – Technique • Have you changed your technique for cortical removal with femto? – No change – “Pneumodissection” – New hydrodissection cannula design – Hydrodissection post nuclear removal – Bimanual – Other Waring IV, GO
Cortex Removal with Femtosecond Laser – Laser Settings • Have you changed your laser settings to improve ease of cortex removal and has this affected your capsulorhexis? – Decreased depth of capsulorhexis cut – Lowered energy for capsulorhexis cut – Changed fragmentation pattern – Lowered energy for fragmentation pattern
Waring IV, GO
Cortex Removal with Femtosecond Laser – Etiologies • Why do you think cortical removal is different with femto assisted cataract surgery? – Lack of fimbrication/tags – Energy changes phyisical property – Plasma gas release changes physical property – Pressure from gas release – Other?

What would you do for this cataract patient who desires Premium IOL? • Toric IOL • Presbyopic IOL – If so – which one?
Handling the Unhappy Presbyopic IOL Patient
• How do you handle unhappy patients on the one-two week postop visit? – End up off target • 20/30 UCVA or worse • Insufficient reading ability
Handling the Unhappy Presbyopic IOL Patient • How do you handle unhappy patients on the onetwo week postop visit? – Night Vision Complaint at the 1-2 week visit? – Can any interventions help? • Alphagan/pilo? • Yag? • Other options for patient?
• How do you handle the patient that wants to wait for night vision complaints to improve before proceeding with second eye?
Handling the Unhappy Presbyopic IOL Patient
• How soon after cataract surgery will you Yag? – Crystalens vs multifocal?
• Does this take away your option for an IOL exchange?

How would you counsel this patient seeking maximum spectacle independence? • 70-year-old • -12.00D myope • Succesful with monovision RGPs for 30 years – 1.5 cylinder on topography
How would you counsel this patient seeking maximum spectacle independence? • 52-year-old nearly emmetropic stockbroker who loves to play golf. – No cataract – Wants to be spectacle independent at all costs.
Short eye with 4D astigmatism • Axial length <20 • Predicted Alcon Toric IOL power for plano: 36 – Highest IOL power for Toric IOL = 30
• Options
– Toric IOL with LRI and piggyback IOL – Toric IOL with LRI followed by LVC – Monofocal IOL with LRI, followed by LVC – Other options
Preop Dry eye & Blepharitis? • How commonly do these conditions impact your Presbyopic IOL results?

Surgery Planning Patient Discussion • Do you make a recommendation on a Presbyopic lens type – or give patients multiple options? • How important are your staff in communicating with patients regarding presbyopic IOL choices?
Conclusions • Femto cataract surgery is an exciting technology which will continue to grow in use in the US • Presbyopic IOLs can provide improved patient satisfaction – but requires careful preoperative planning and potential for more challenging postoperative care

• The Centers for Medicare and Medicaid Services today released guidance to clarify when beneficiaries can be billed for non-Medicare-covered services using the femtosecond laser to insert a premium refractive intraocular lens, after cataract surgery. – CMS indicates that it is possible to bill beneficiaries for use of the femtosecond laser for services such as imaging when a premium refractive IOL is implanted, but not when a conventional IOL is used. – The agency specifically does not permit billing for the use of femtosecond laser technology in conjunction with Medicare-covered steps of the cataract surgery, such as the phaco incision, capsulotomy and lens fragmentation
Technologies that can help expand patients visual • Toric IOLs • Presbyopic IOLs • Preoperative testing to identify subtle preop conditions • Technologies to make surgery less risky • Technologies to help patients ende
• “The physician may take into account the additional physician work and resources required for insertion, fitting, and visual acuity testing of the presbyopia-correction IOL” • Allows surgeons to charge for non-covered services – Preoperative testing • Topography • OCT of the macula • Other tests
