  1. EYEDIFF PLUS +3.50D Diffractive Multifocal IOL “A New Alternative” Prof. Dr. Daniel H. Scorsetti University of the Salvador - Catholic PontificiaUniversity of Argentina Faculty of Medicine - Faculty of Medical Sciences Chair of Ophthalmology Buenos Aires, Argentina

  2. Eyediff Plus +3.50D: TechnicalSpecifications

  3. EYEDIFF Plus Presbyopic IOL • Diffractive Technology • Perfect Light Distribution for Distance &Near( 60/40)‏ • Addresses Cataract Patients with or without Presbyopia • Allowed Patients a High Level of Freedom From Glasses in clinical trial

  4. Full Optic Regular Diffractive IOL Advantages • Provides multifocal vision • Reduced pupil dependency • Balanced distribution of light • Able to tolerate some decentration

  5. Full Optic Diffractive IOL • Disadvantages • Potential for Scattering of light and glare and halos at nightbut • Advantages • Provides multifocal vision • Reduced pupil dependency • Balanced distribution of light • Able to tolerate some decentration • * Creates Halos and scattering Light

  14. AsphericOptic (Aberration Neutral)

  15. 360° SquareEdge

  16. EYEDIFF Plus 360⁰Square Edge • Edge thicknesscorrespond to standard designed IOLs • Square edge design • Perfect centration in thecapsular bag • Perfect opticalperformance • Extremely low incidenceofPCO • Anti Z effect Haptic design

  17. IOL Power calculation • Careful Keratometry • 1.0D corneal power error affects 1.3 to 1.6D IOL power calculation • Careful Axial Length • 1.0mmAL error affects the post-operative refraction by 1.2 to 2.5D aprox. • IOL Master: SRK II--------- 118.6  • SRK T--------  118.4 • Holladay 1 - sf--- 1.37 • Haigis ----- a0=0.95, a1=0.4, a2=0.10 • Hofer - pACD-- 5.17 • Aim Emmetropia & Astigmatism <1.0D • A-Const. & ACD ( Surgeon Factors)‏

  18. Clinical Trial • Objective: to compare the visual quality preop and postop., between 2 multifocal IOLs and 1 monofocal • Material and methods : 60 eyes of 30 pts. divided into 3 groups, informed and signed assent, cataract degrees II and III, older than 55 years (average 60 years), without ocular disease or astigmatism > 1.0D. Bilateral implants, the same IOL in every patient (not mix and match) • Equipment: Alcon InfinityTechnique: Facotorsional with Ozil IP, 2.2mm (intrepid)Incision in the steepest axis and the same protocol in all cases • Group 1: 10 pts. Acrysoft IQ • Group 2: 10 pts. Acrysoft Restor • Group 3: 10 pts. EYEDIFF PLUS +3.5D

  19. Clinical Trial • Preop Complete ocular exam: • UCVA & BCVA: far, intermediate (70 cm) and near (40 cm) • Pentacam HR • IOL Master • Contrast Sensibility : photopic and mesopic • NEI VFQ-25 Questionnaire with Apéndix NEI VFQ-39 (in Spanish) • 6 questions to evaluate visual general health • 20 questions to evaluate difficulties in visual activities • 13 questions to evaluate level of acceptance of visual loss NEI VFQ: National Eye Institute, Visual Function Questionnaire

  20. Clinical Trial • Postop complete examination : days 1 - 7- 30 - 90 • UCVA & BCVA: far, intermediate (70 cm) and near (40 cm) • Pentacam HR • Contrast Sensibility : photopic and mesopic • NEI VFQ-25 Questionnaire with Apéndix NEI VFQ-39 (in Spanish) • 6 questions to evaluate visual general health • 20 questions to evaluate difficulties in visual activities • 13 questions to evaluate level of acceptance of visual loss • Follow-up 3 months

  21. Results • Questionnaire • Group 2 and 3: better in postop. to read newspaper and close vision activities. • Group 3:less difficulty in night driving, But without statistically significant difference with 2. • Group1: statistical significant difference to favor to drive by night • Without intraop complications • Without PCO • Descentrations • 2 minor in group 2 • 1 minor in group 3 • Halos/Glare • 3 tolerable in group 2 • 2 tolerable in group 3

  22. Results FAR – GROUP 1: Acrysoft IQ UCVA BCVA

  23. Results FAR – GROUP 2: Acrysoft Restor UCVA BCVA

  24. Results FAR – GROUP 3: EYEDIFF PLUS UCVA BCVA

  25. Results NEAR – GROUP 2: Acrysoft Restor UCVA BCVA

  26. Results NEAR – GROUP 3: EYEDIFF PLUS AV S/C AV C/C

  27. Intermediate Vision (70 cm)

  28. EYEDIFF Plus

  29. EYEDIFF Plus

  30. Conclusions • Less adverse effects • Good results post-surgery • Individual map with MTF and topography of IOL power • Variety of powers for near • First Customized IOL • Cost
