Abstract Details


We studied the cornea surgical correction to reduce the presbyopia effect by blended vision laser method (Presbiond)


Madrid Quiron University Hospitalc/ Diego de Velazquez, 1 28223 Pozuelo de Alarc�Ã�³n (Madrid)


We carried out a study with 30 patients in 3 groups: a) Group I(Hyperopes): �.50/�.50 D b) Group II(Myopics< 3D): -0.75/-2.75 D c) Group III(Myopics > 3D): -3.00/-7.00 D Wasca (wavefront analyser), ATLAS (Corneal topographer), CRS-Mosta (treatment planning), MEL 90 (Excimer laser) were used.


We Analyzed the prevalence of the ocular dominance in each group. The mean binocular corrected far/near VA pre and post in each group. Post op spherical equivalents in dominant eye and non dominant eye. Post op refractive results in dominant eye and non dominant eye.


- Presbyond is an evolution of LVB software - Controlled induction of z(4,0) plus monovision.- Introduces the item of Functional Age (accommodation width)- Problems:* No access to the induction algorithm (hidden algorithm)* Not knowing the z(4.0) target * Predictability balance vs z(4.0) (UDVA is very good!!!) Personalized adjustments
