PURPOSE
This is the first clinical trial to evalutate safety long term visual
outcomes in a selected group of patient with cataract of this
"premium" IOL, available in two versions:
modified “C” style
Micro-Incision Plate style
“Progressive Multifocal” lens that uses a new optical geometry.
Materials and methods

35 patients (20 F ,15M. Mid age 56) had bilateral
Progressive Multi-Focal Intraocular Lenses implants
with a non-linear reading add from +3.0 Diopter to
+4.5(progressive)during cataract surgery (
PRESBIOPTICx by IMT, Cartersville GA USA). Exclusion
criteria included but was not limited to astigmatism
>1D, diabetic retinopathy, maculopathy and previous
ocular surgery.

First Lens Implanted - If emmetropia & near vision
achieved then the second lens Implanted is identical.
• First Lens Implanted - If near vision is not
achieved then second lens can correct the problem.

RESULTS: 12 to 24 months follow up

Total freedom from glasses was achieved in 28 patients
(>80%) with two similar near addition implants (Standard
PRESBIOPTICx).



5 patients received an extra 0.40D addition for the second
eye(Customized PRESBIOPTICx). Considering this group too, 33
patients (95%) achieved J2 best uncorrected near visual acuity
with bilateral vision.
100%of the patients achieved 20/25 or better uncorrected
visual acuity for distance.
2 Patients complained some temporary (2-3 months) night
vision problems such as glare, halos and sparkles (5,7%).
CONCLUSION



This revolutionary progressive addition system for
multifocal IOLs provides a excellent visual acuity for
distance and near and it can be eventually
customized.
Full range vision can be achieved in 95% of the
cases .
We found a significant reduction of temporary side
effects of multifocal IOLs such as glare, halos and
sparkles (5,7%).
