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.
3
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 near vision is not achieved then second lens can correct the problem. DIOPTER OPTICAL ADD 2 nd Lens Availability

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%).
10
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%).
