AS VITREORETINAL SURGEONS HOW DO WE AVOID FORFEITING CONTROL?
SYSTEMS RELEVANT TO THE OPERATING ROOM
SYSTEM COMPONENTS
Facility Equipment Surgeon
• Expense• Personnel
• Salary• Benefits
• Anesthesia Equipment costs• Property costs
• Rent• Overhead
• Maintenance costs• Influencing factors
• Efficiency• Regional Cost of Living• Regional Property values
• Income
• “Facility Fee”
• Set by Payers
FACILITY: EXPENSE AND INCOME
• Expense• Cost versus quality
• Durable Capital Costs• Surgical instrumentation• Anesthesia equipment• Furniture • Information technology
• Disposable costs• Instruments• Surgical Packs• Anesthesia Packs• Medications
• Income
• Hospitals
• Limited pass through reimbursement on disposable instrumentation, medications, etc.
• ASC
• None
EQUIPMENT ECONOMICS
• Expense And Income Dictated by:
• Efficiency
• Productivity
• Case Type
• Payer Contract
SURGEON ECONOMICS
HOW DO WE MODIFY THESE FACTORSTO BENEFIT THE PATIENTS, THE PAYERS,
AND THE SURGEON?
ECONOMICS 101
• Increase Income• Decrease Expenses
• Most challenging side of the economic equation.
• Largely at the mercy of the Payer contracts
• Increase efficiency
• Increase scope of practice
• Ability to manage previously “unmanageable” (ex: macular holes, or exudative AMD)
• Capture part or all of the global fee(professional fee and facility fee)
INCREASE INCOME
• Eliminate overhead costs
• Personnel
• Equipment
• Facility

PEARL (VERSAVIT PROTOTYPE)
Variable Cut Rate
Variable Aspiration Pressure
50 cc Cassette
Variable Air InfusionPressure
Single Variable LED Light Source
PERSONAL EXPERIENCE (PROTOTYPE)• 7 cases
• ASC = 6
• Office = 1
• Procedures
• Macular Pucker (4)
• Macular Hole (1)
• Vitreomacular traction (1)
• Non-clearing vitreous hemorrhage with retinal tear (1)
PROTOTYPE PERSONAL EXPERIENCE• Efficient• Quiet• Good illumination• Extremely user friendly…”plug and play”
PROTOTYPE PERSONAL EXPERIENCE• Prototype Glitches
• Foot pedal failure due to broken connection (cases 1, 2)
• Temporary loss of cutting ability (case 5)
• Surgical Complications• None
PROTOTYPE PERSONAL EXPERIENCE• Limitations
• No silicone oil infusion
• No fragmatome
• No diathermy
PERSONAL EXPERIENCE• Surgical maneuvers performed
• Complete vitrectomy
• Injection and removal of vital dye• Membrane peeling
• Fluid-air exchange
• Indirect laser retinopexy
• Endolaser retinopexy*
* Endolaser performed with separate unit (Iridex)
CASE EXAMPLE: CASE 5 (OFFICE)
OUTCOMES• Vision: 7/7 > 2 lines of vision
• Preop Visual Acuity: 20/102 (range = 20/40 – 20/800)• Postop Visual Acuity: 20/48 (range = 20/20 – 20/400)
• Anatomic success: 7/7 cases • Surgical time: 38 minutes, mean (range = 24 – 52 minutes)• Follow-up Period: 4 months, mean (range = 3 – 6 months)
PROTOTYPE DESIGN CHANGES• Switches/Knobs
• Eliminate the rheostats and exchange them for switches
• Illumination• Add a second light port for multiple illumination sources or in case of light source failure.
• Vacuum Pressure• Increased and adjustable
• Foot Pedal• More functional foot switch
PROTOTYPE DESIGN CHANGES• Create a platform for expansion
• In time, surgeons will push the limits as to which cases they will conquer.
• The machine will not be the limiting factor. • Accessories will be the “App” equivalents
VERSA VIT SPECS
• Weighs 25 pounds
• Footprint less that one cubic foot of space
COMPACT PORTABLE VITRECTOMY UNIT (SYNERGECTICS)

POSSIBLE SOLUTION:OFFICE PROCEDURE ROOM BASED VITRECTOMY• Benefits
• Eliminates significant overhead costs
• Example: no need for pre- or post-op registered nurses
• Utilize our own ophthalmic technicians…already “on-the-clock.”
• Facility
• Already “bought-and-paid-for”
• Maximizes utilization of assets
• Global Fee paid to practice (professional fee and facility fee)
• Convenience
• Efficiency
• No anesthesia costs for Payers
OFFICE PROCEDURE ROOM BASED VITRECTOMY: RISKS AND LIMITATIONS AND CONSIDERATIONS
• Patient Safety• Case limitations• Financial issues
• Endophthalmitis risk
• Mortality risks
• No Anesthesiologist in the event of cardiovascular event
OFFICE PROCEDURE ROOM BASED VITRECTOMY: SAFETY
• Case Selection Critical!
• No complex cases
• No lengthy cases
• No medically or mentally unstable patients
OFFICE PROCEDURE ROOM BASED VITRECTOMY: CASE LIMITATIONS
OFFICE PROCEDURE ROOM BASED VITRECTOMY: FINANCIAL CONSIDERATIONS• Surgeon fees remain unchanged
• Intangible cost benefits for the surgeon and patient
• Eliminates travel to surgical center
• Not dependent on surgical center availability
• Convenience factor
• Facility charges…
• Conversations with Payors
• Goal: Global fees go entirely to the practice
