IOL Power calculationIOL Power calculation
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
Clinical TrialClinical 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 health20 questions to evaluate difficulties in visual activities 13 questions to evaluate level of acceptance of visual loss
Clinical TrialClinical Trial
NEI VFQ: National Eye Institute, Visual Function Questionnaire
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 health20 questions to evaluate difficulties in visual activities13 questions to evaluate level of acceptance of visual loss
• Follow-up 3 months
Clinical TrialClinical Trial
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
