The Marvellous Journey of Cataract Surgery Has Always Been Based on Progress and Surgical Evolution Nobody Has the Opportunity to Block the Progress of Science From The Very Beginning Cataract Surgery Has Provided for the Removal of Lens Which Progressively Loses Transparency Today Refractive Cataract Surgery Is the Most Common and Efficient Way to Correct Refractive Defects, Myopia, Hyperopia, Astigmatism and to Overcome Presbyopia Limitations The Good News is That You Have the Opportunity to Adopt These Extraordinary Updates Without Having to Overturn Your Surgical Skills It Is However Necessary To Revolutionize the Organization of the Surgical Center by Taking Advantage of the Possibility of Introducing the Use of the Most Advanced Technologies The Most Challenging Thing is to Succeed in Moving from an Organizational System Based on High Numbers at Low Cost Embracing High Tech Refractive Cataract Surgery : This is The Change Cost Efficiency is a Non Medical Indication Acting Normally in Contries Members of The Third World Community No Patient Has Ever Thanked Me for Spending Less and Not Giving Him the Best Care M Piovella 2010
Today It Is Necessary to Provide a Good Quality of Vision After Cataract Surgery Loss of Contrast Sensitivity Penalizes All People After 60 Years of Age In-focus Image Quality - Characterization How to Combine Different Image Dimensions and Corresponding Contrasts Into a Single Characteristic? Modulation Transfer Function (MTF) = Modulations at the Image Plane as a Function of Spatial Frequency MTF is Quantitative Measure of the Ability of Optical System (IOLs) to Reproduce Contrast of Original Object by Its Image
MTF Quality of Vision Drops Down From 100% to 0% with Only 8 Degree Axis Rotation Misalignment with a Toric IOLs Implant to Correct 2 D Astigmatism MTF (50 lp/mm) Sensitivity vs Toric IOL Rotation Errors The Importance of Callisto Markerless Digital System MTF WITH CORNEA CYLINDER CORRECTED ACE, 550 nm, 5MM MTF@50lp/mm 1.00 0.90 0.80 0.70 0.60 0.50 0.40 0.30 0.20 0.10 0.00 0 2 4 6 8 10 12 14 16 18 20 ROTATION (DEGREES) 0.0D 0.5D 1.0D 2.0D 2 D Cylinder Correction Toric IOL Pupil Size 5 mm E (20/40) sensitivity to IOL rotation errors of 0, 5, 10, 15, 20 degrees 5.0 mm Multifocal Toric Optic is More Sensitive to Cylinder Misalignment then Monofocal Toric Optic
Residual Postop Astigmatism is Responsible for the Biggest Complains Concerning Low Quality of Vision Low-Order Aberrations Due to Post-operative Refraction Residues Significantly Penalize Quality of Vision and They Multiply Exponentially the Effects of High-Order Aberrations Such as Coma and Trefoil Corneal Astigmatism Management : Toric IOLs When 0.75 Diopters of Astigmatism is Detected with Most Advanced Technology This Means Implanting Multifocal Toric Intraocular Lenses in 50% of Patients Undergoing Cataract Surgery The Use of IOL Master 700 and the Callisto System is Mandatory The Postop Refractive Gold Range to Achieve Good Quality of Vision is 0.50 Diopters The Use of Latest-Generation Autorefractometer Allows a Perfect Identification of the Residual Refractive Defects The Most Widely Used EDOF IOLs Do not Allow Precise Identification of the Postoperative Residual Refractive Defect by the Latest Generation Autorefratometers. Moreover, Postoperative Refractive Stability is Normally not Determined Before 30 days Postoperatively Zeiss Trifocal Lenses Allow Precise Identification of Postoperative Residual Refractive Defect in Real Time. Normally Maintain a Stable Refraction Two Days After Surgery

Why I Decided to Implant Zeiss AT LISA tri and Toric IOLs in My Own Eyes I started to Implant Modern Multifocal IOLs Routinely in 2006 I Started Adopting Zeiss Bifocal IOLs Despite my Resistances in Adopting Plate Instead of Traditional C Haptic Because in 2010 It Was the Only IOL to Provide Toric Correction Zeiss AT LISA tri Was My First and Standard Choice for Presbyopia Correction Since Its Introduction in 2012 My Center Was the Monitor Centre for Multicenter Victory Study on Zeiss AT LISA tri Toric I Personally Measured Postoperative Refraction of All Patients Using the Most Advanced Technology to Detect The Gold Range ± 0.50 Diopters

Clinical Indications, Patient and Eye Selection and Surgical Center Organization to Adopt Safely and Successfully Advanced Technology IOLs in Refractive Cataract Surgery : The Italian Ophthalmological Society (SOI) Report 1. Dry Eye and Meibomian Glands Disfunction(MGD) Management to Provide Healthy Cornea Surface 2. With Blocked Meibomian Glands Apply Treatments to Unblock the Excretory Ducts of Glands 3. Advanced Biometry: IOL Master 700 or Equivalent Technologies 4. Advanced Biometry Exam Performed Two Times Before and After MGD Management 5. Adopting Different Formulas and New IOLs Calculators Depending Axial Lenght or Previous Laser Vision Correction 6. Continuous Update of Costants 7. Callisto Markerless System or Equivalent Tecnologies to Overcome Eye Cyclotorsion : Avoid Toric IOLs Manual Alignment 8. Corneal Astigmatism Management : Apply Toric IOLs When 0.75 Diopter of Astigmatism is Detected 9. Target Postoperative Refraction : ±0.50 D or Emmetropia 10. Automated Mechanical Capsulotomy More Precise Then Capsulorhexis : It Reduces the Complications Rate of Refractive Cataracts 11. The Importance of an Indication Based Mainly on the Selection of the Eye and not on the Evaluation of the Habits or Requests of Patients 12. Preoperative Normal Convergence,Stereopsis and Near Vision 13. A New Surgical Center Organization 14. Professional Refraction Management
