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.

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
