Aspheric Optic (Aberration Neutral)
360° Square Edge
EYEDIFF Plus 360⁰Square Edge
 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
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)
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 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
 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
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
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
