Visual performance and defocus after unilateral or bilateral implantation of a new Extended Range of Focus lens F. Goes, Jr. MD Antwerp, Belgium
40 % TRIFOCAL IOL EUREQUO: 34 % BIFOCAL IOL WHAT ARE YOU USING TODAY? 18 % EXTENDED DEPTH OF FOCUS IOL
EUREQUO : WHAT DO YOU WANT TO INTEGRATE IN THE NEXT 5 YEARS? 62 % EXTENDED 49 % TRIFOCAL RANGE OF IOL VISION IOL (EDOF)
ZEISS AT LARA L : Light bridge optic design A : Aspheric optics R : Reduced side-effects A : Advanced chromatic optics
The longer the wavelengths, the farther the focal point

EDOF vs MF IOL QOV vs SPECTACLE INDEPENDENCE • Dens cataract : EDOF and MULTIFOCAL IOL • Refractive surgery • Myopic presbyopic patient : EDOF • Hypermetropic patient : MULTIFOCAL • Demanding patient : EDOF
• 49 eyes of 32 patients • 17 bilateral patients • 15 unilateral patients • More and more, this lens is being used STUDY DESIGN together with • a stronger multifocal lens • a monofocal lens • or in unilateral cataract patients
• Automated and subjective refraction • Slitlamp and pressure • Detailed fundus examination • Topography PREOP • Endothelial specular microscopy TESTING • OCT-scan of the retina • Tear osmolarity measurement in case of dry eye • Interview with patients looking for expectations and character grading

AT T LARA Wide range of focus Spectacle independence for intermediate and CONCLUSION far distances Less visual side-effects than with multifocal IOLs
AT T LA LARA An aberration-neutral aspheric design and advanced chromatic correction for optimized CONCLUSION contrast sensitivity Mini-monovision increases spectacle- independence but creates more side-effects
