Visual performance and defocus after unilateral or bilateral implantation

f a new Extended

Range of Focus lens

F. Goes, Jr. MD

Antwerp, Belgium

SLIDE 2

EUREQUO: WHAT ARE YOU USING TODAY? 40 % TRIFOCAL IOL 34 % BIFOCAL IOL 18 % EXTENDED DEPTH OF FOCUS IOL

SLIDE 3

EUREQUO : WHAT DO YOU WANT TO INTEGRATE IN THE NEXT 5 YEARS?

49 % TRIFOCAL IOL 62 % EXTENDED RANGE OF VISION IOL (EDOF)

ZEISS AT LARA

L : Light bridge optic design A : Aspheric optics R : Reduced side-effects A : Advanced chromatic optics

SLIDE 5

The longer the wavelengths, the farther the focal point

STUDY DESIGN

49 eyes of 32 patients
17 bilateral patients
15 unilateral patients
More and more, this lens is being used

together with

a stronger multifocal lens
a monofocal lens
or in unilateral cataract patients

SLIDE 11

PREOP TESTING

Automated and subjective refraction
Slitlamp and pressure
Detailed fundus examination
Topography
Endothelial specular microscopy
OCT-scan of the retina
Tear osmolarity measurement in case of dry eye
Interview with patients looking for

expectations and character grading

SLIDE 15

AT T LARA Wide range of focus Spectacle independence for intermediate and far distances Less visual side-effects than with multifocal IOLs

CONCLUSION

SLIDE 16

AT T LA LARA An aberration-neutral aspheric design and advanced chromatic correction for optimized contrast sensitivity Mini-monovision increases spectacle- independence but creates more side-effects

CONCLUSION
