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

2 Eyediff Plus +3.50D: Technical Specifications

3  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 EYEDIFF Plus Presbyopic IOL

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

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

14 EYEDIFF PLUS - Predictable refractive outcome Analysis of the mistake : Square root of the sum of the squares Warren E. Hill, MD, FACS

15 Aspheric Optic (Aberration Neutral)

16 360° Square Edge

17  Edge thickness correspond to standard designed IOLs  Square edge design  Perfect centration in the capsular bag  Perfect optical performance  Extremely low incidence of PCO  Anti Z effect Haptic design EYEDIFF Plus 360⁰Square Edge

18  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 SRK T Holladay 1 - sf Haigis a0=0.95, a1=0.4, a2=0.10 Hofer - pACD  Aim Emmetropia & Astigmatism <1.0D  A-Const. & ACD ( Surgeon Factors)‏ IOL Power calculation

19  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 Infinity Technique : 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 Clinical Trial

20  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 Clinical Trial NEI VFQ: National Eye Institute, Visual Function Questionnaire

21  Postop complete examination : days 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 Clinical Trial

22  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 Results

23 UCVABCVA Results FAR – GROUP 1: Acrysoft IQ

24 UCVABCVA Results FAR – GROUP 2: Acrysoft Restor

25 Results FAR – GROUP 3: EYEDIFF PLUS UCVABCVA

26 UCVABCVA Results NEAR – GROUP 2: Acrysoft Restor

27 AV S/CAV C/C Results NEAR – GROUP 3: EYEDIFF PLUS

28 Intermediate Vision (70 cm) GROUP 2 Acrysof Restor DECIMALDISTANCE INTERMEDIATE WITHOUT CORRECTION cm INTERMEDIATE WITH CORRECTION cm GROUP 3 – EYEDIFF PLUS DECIMALDISTANCE INTERMEDIATE WITHOUT CORRECTION cm INTERMEDIATE WITH CORRECTION cm
