Abstract Details

Purpose:

to evaluate visual acuity, defocus curve, contrast sensitivity and patient satisfaction after bilateral implantation of an extended depth of focus (EDOF) IOL (Amo Tecnis Symfony) compared to a multifocal IOL (MIOL) with an additional power of 2.5 diopters(D) (Alcon Acrysoft ReStor) and a multifocal IOL with an additional power of 3.0 diopters (Alcon Acrysoft ReStor).

Setting:

Ophthalmology Unit, department of Neurosciences, University of Verona, Verona Italy and Centro Oftalmochirurgico Carones, Milan, Italy.

Methods:

310 eyes of 155 patients affected by senile cataract undergoing bilateral phacoemulsification were divided in three randomized groups. Group 1 (55 patients) was bilaterally implanted with an EDOF IOL, group 2 (50 patients) was bilaterally implanted with a low addition MIOL (+2,5D) and group 3 (50 patients)with a +3.0D addition power MIOL. All patients underwent a post operative follow-up of 3 months during which was evaluated binocularly: uncorrected and corrected distance (4m), near (40 cm) and intermediate (60 cm) visual acuity. It were also assessed defocus curve, contrast sensitivity (CS), aberrometry (OPD Scan III Nidek) and patients satisfaction (NEI RQL-42).

Results:

No statistical difference was found in uncorrected and best corrected distance visual acuity between all three groups. The defocus curve shows better visual acuity from -0,25D to - 1,25D for the group 1, while group 2 performs better from -1,25 to -1,75D. Group 3 shows better visual acuity from -1,75 to -3,00 D. Better CS and better values for RMS and MTF were found in group 1. All patients in groups 1 and 2 reported no significant visual disturbances and high level of satisfaction while in group 3 more glare and less spectacle independence were reported.

Conclusions:

According to our results, all groups achieved an excellent visual acuity for distance. While group 1 and 2 perform better for intermediate, group 3 shows excellent visual acuity for near. The EDOF IOL shows better values in terms of quality of vision while group 3 shows higher incidence of glare. EDOF IOLs and low add MIOLs can be considered a good option in routine cataract surgery in patients willing spectacle independence
