Why did I need the

Light Adjustable Lens?



I, like most of us, was far away

from a precise achievement of

targeted refraction in all cases.

• a correction of astigmatism up to 2.00 D

• a correction of residual refractive errors

of up to +/- 2.00 D spherical

post-operatively.

The Light Adjustable

Lens allows



From October 2008 until Jan. 2012,

I have implanted the Light Adjustable

Lens into 183 eyes

28.2.2009 Dr. med. Sylvia Paulig AugenPraxisKlinik Cottbus

with 93 eyes adjusted for distant vision

with 55 eyes adjusted for near vision.

164 eyes are presented here, 4 patients (8 eyes)

are still waiting for the adjustment.

We found 27 eyes with a complicated initial situation like

amblyopia, strabism or AMD (future presentation).



In the 93 eyes adjusted for distant vision,

almost all eyes (86 out of 93), had an UCVA

of 20/20 or better…

near vision in the very same eye.

… and different from MONOVISION,

my LAL patients had great stereoscopic

vision. (These are our last 37 patients)

… different from the multifocal and standard IOLs,

the defocus curves of the LALs indicate asphericity,

repeatability and are superior to standard IOLs at

all distances.

With a large aperture (Iris) a sharp image depends

on the optimized curvature (asphericity) of the lens.

Why BINOVISION?

28.2.2009 Dr. med. Sylvia Paulig AugenPraxisKlinik Cottbus

After implanting the first lenses,

without glasses our patients noticed

• good reading, intermediate and distant vision

• good stereoscopic vision

• very good depth perception

• excellent quality of vision (patient reports).



BINOVISION is seeing

without Glasses by

Modification of Asphericity

of the LAL

• Adequate near, intermediate and distant vision

in the same eye without glasses

• Stereoscopic binocular vision at all distances

(near, intermediate and distance)

• superior vision compared to that provided by

other lens based and refractive methods

presently used



In our clinic we use the possibility of

modification of asphericity of the LAL

as a highly satisfying alternative for

patients who desire presbyopia

correction and seeing without glasses.



LAL offers the most valuable

possibilities for our patients and

Binovision with the LAL is the

pink of perfection.

BINOVISION

The answer we’ve been

all waiting for.

Seeing without Glasses
